La polidactilia en la especie humana se debe a un alelo dominante. Entre Francisco y Martha, ambos abuelos de Santiago, uno de ellos tenía polidactilia, sin embargo Juan su hijo (papá de Santiago) nació normal. A pesar de ello Santiago es polidactílico. La explicación a esta situación es que
Respuestas:
A)Como Juan nació normal (aa) la única posibilidad para que Santiago su hijo naciera con polidactilia era que su madre lo fuera también.
B) Como uno de los abuelos era aa (homocigoto recesivo-normal) y el otro Aa (heterocigoto-polidactílico), Juan nació probablemente aa (homocigoto recesivo-normal) y por ello no hay manera que Santiago naciera polidactílico.
C) Como uno de los abuelos era aa (homocigoto recesivo-normal), Juan nació probablemente aa (homocigoto recesivo- normal) y por ello Santiago es polidactílico.
D) Como Francisco y Martha eran Aa (ambos heterocigotos-polidactílicos), Juan nació probablemente AA (homocigoto dominante- polidactílico) y por ello Santiago es polidactílico.
Answer:
A)Como Juan nació normal (aa) la única posibilidad para que Santiago su hijo naciera con polidactilia era que su madre lo fuera también.
Explanation:
La polidactilia es una malformación causada por un alelo dominante asociada con al aparición de más de 5 dedos en cada pie o más de 5 dedos cada mano. Un alelo dominante es una variante génica capaz de enmascarar la expresión de un alelo recesivo en individuos heterocigotos, es decir, en individuos portadores de una copia del alelo dominante y una copia del alelo recesivo para un gen en particular. De este modo, un alelo dominante es por definición aquel que será expresado en el fenotipo, con lo cual el único modo en el cual Santiago sea portador del alelo dominante causante del rasgo "polidactilia" es que él lo haya heredado, ya sea del padre o de la madre (es importante aclarar que también el alelo dominante puede haber surgido por mutación en la línea germinal). En este caso sabemos de acuerdo al enunciado que el padre de Santiago no tiene polidactilia y por lo tanto no es portador del alelo dominante, con lo cual se espera que Santiago haya heredado esta condición de su madre.

21. What determines the kind of genes an organism
possesses?
Answer:
The kind of genes an organism possesses is determined by the order of the nucleotide bases in the organism's DNA.
Answer:
The kind of genes an organism possesses is determined by the order of the nucleotide bases in the organism's DNA. ... The order of bases as you go down the rungs of the ladder determine what genes an organism will have, and therefore, what traits it will have.
Explanation:
Fun facts:
Genes carry the information that determines your traits which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes. ... And chromosomes are found inside cells. Your body is made of billions of cells.

A researcher dried a feedstuff and determined that it contained 10 percent moisture. he took 1 gram (dry) of it and combusted it in the bomb calorimeter. the calorimeter contains 1 kg of water. The temperature was raised 2.7 degrees centigrade. Two kilograms (2000 grams) of dry matter of the material was fed to a pig each day for several days. the fecal collections of the pig averaged 200 grams dried per day for the last few days. the feedstuff analyzed 2.41 percent nitrogen (dry basis); the feces (dry basis) analyzed 4.6 percent nitrogen. (hint: the feedstuff contained _____ grams protein, the feces contained _____ grams protein.)
Answer:
Explanation:
The objective of the information given is to calculate the apparent digestible dry matter present in the feedstuff(%) and the apparent digestibility of the protein?
From the given information:
The apparent digestible dry matter present is:
[tex]=\dfrac{ (\text{Dry matter fed to the pig} - \text{Fecal matter of the pig} )}{\text{Dry matter fed to the pig}} \times 100 \%[/tex]
where;
Dry matter fed to the pig = 2kg = 2000 g
Fecal matter of the pig = 200
∴
The apparent digestible dry matter present = [tex]\dfrac{2000-200}{2000}\times 100\%[/tex]
[tex]=\dfrac{1800}{2000}\times 100\%[/tex]
= 90
Amount of Nitrogen(i.e. the protein) content present in the feedstuff = 2.41%
i.e.
2.41 g/100 g OR 48.2 g/2000 g feed
Amount of protein present in feces = 4.6% (4.6 g/100 g OR 9.2g/200g of feed)
∴
apparent digestibility of the protein is:[tex]=\dfrac{\text{Amount in feed }- \text{Amount in feces}}{\text{Amount in feed }}\times 100[/tex]
[tex]= \dfrac{(48.2 - 9.2)}{48.2}\times 100[/tex]
[tex]= \dfrac{39}{48.2}\times 100[/tex]
= 81%

Which of the following is an example of non Mendelian pattern of inheritance
Answer:
Genomic imprinting represents yet another example of non-Mendelian inheritance. Just as in conventional inheritance, genes for a given trait are passed down to progeny from both parents. However, these genes are epigenetically marked before transmission, altering their levels of expression.Answer:
Just as in conventional inheritance, genes for a given trait are passed down to progeny from both parents.

What is stimulated by high extracellular fluid volume (ECFV) and works to increase GFR and urine output?
Stretching of the atrial muscle cells releases a hormone called atrial natriuretic factor (ANF). ANF relaxes the juxtaglomerular (JG) cells of the afferent arteriole and thereby increases GFR and urine output.
Suppose that you are able to sequence a portion of Dr. Ogden's genome. The DNA sequence below is a stretch of one of the genes.
TAC CGT ATA AAA AAT TAA CTT AGA CGT GCT CTT TCT CTT CGA GAA GAC ATA TTA CTT CGT TGA ATC

The mRNA processed transcript will be: AUG GCA UAU UUU UUA AUU GAA UCU GCA CGA GAA AAU GAA GCA ACU UAG.
What is transcription?In genomics, transcription is the method of generating an RNA copy of a gene's DNA sequence. This copy, known as messenger RNA (mRNA), transports the protein information encoded in the gene's DNA.
This RNA copy, known as messenger RNA (mRNA), contains the genetic information required for a cell to produce proteins.
It transports information from the cell's nucleus to the cytoplasm, where proteins are produced.
The entire gene is copied into a pre-mRNA, which includes exons and introns, during transcription. Introns are removed and exons are joined to form a contiguous coding sequence during the RNA splicing process.
Thus, as the introns are getting removed completely, the mRNA sequence for the given DNA sequence will be: AUG GCA UAU UUU UUA AUU GAA UCU GCA CGA GAA AAU GAA GCA ACU UAG.

Some experts attribute the increase in ADHD diagnoses to an increased awareness of the disorder, while others attribute the increase to ______ diagnoses.
Answer:
incorrect
Explanation:
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders affecting children. ADHD is characterized by different behaviors that include one or more of the following symptoms: inattention (poor concentration), impulsivity (interrupting behavior) and hyperactivity (state abnormally active). It has been reported that DHD diagnoses in children between 4 and 17 years of age dramatically increased from 6 percent (6%) during the period 1997-1998 to 10 percent (10%) during the period 2015-2016. Although the causes of this increase have not been established, the American Psychiatric Association (APA) indicates that the increase might be due to the increased access of communities historically relegated to receive care and decreased stigma to be diagnosed with ADHD. Other possible causes range from chemical factors to unhealthy habits during pregnancy (e.g., smoking, substance abuse, poor nutrition). On the other hand, it has also been proposed that this increase may be as a result that ADHD is often misdiagnosed and confused with other conditions (e.g., bipolar disorder, autism, kids being kids, etc).

Why is the temperature at the extremities, such as the fingers,
sometimes colder than the core body temperature?
O A. So that less energy is lost in cold environments.
OB. The fingers need to be colder to protect the durability of the nails.
C. The fingers do not have thermoregulation mechanisms.
D. So that more energy is lost in cold environments.
Answer:
A. so that less energy is lost in cold environments.
Explanation:
When it’s cold outside, your body makes sure to keep the blood flowing to your core and vital organs to keep them warm. This can change the amount of blood flow to your hands and feet, making them feel cold. This is normal. The blood vessels in your hands and feet constrict (spasm) when it’s cold, to prevent heat loss from your core
