In cats, coat color is an X-linked trait with incomplete dominance. Yellow coat is caused by the allele XT and black coat by the allele Xt. A tortoise cost is caused by the heterozygous condition. What is the correct way to represent the genotype of a male cat with a black coat
Answers
Answer:
The genotype of a black male is XtY
Explanation:
Available data:
coat color is an X-linked trait with incomplete dominance.Yellow coat is caused by the allele XTBlack coat by the allele Xt.Tortoise coat is caused by the heterozygous conditionSo,
females genotypes females phenotype
XTXT → Yellow coat XtXt → Black coat XTXt → Tortoise coatmales genotype males phenotype
XTY → Yellow coat XtY → Black coatMales only carry one X chromosome, so they can only be either black - XtY- or yellow -XTY-.
Females are the only ones that can express the tortoise coat.
The correct way to represent the genotype of a male cat with a black coat - XtY
We know that,
In cats, coat color is an X-linked trait - it means it is influenced by the X allele onlyIn cats, coat color is shows incomplete dominance - it means if corresponding alleles present together they will show an intermediate coat color.the allele XT - Yellow coatthe allele Xt - black coatXTXt (heterozygous) - tortoise coat (incomplete dominance)In X linked traits heterozygous conditions are not possible in males as they have only one X allele and the other is Y allele.So,
Female cats genotype would be:
XTXT - female cat with yellow coatXTXt - female cat with a black coatXtXt - female cat with tortoise coatMale cats genotype:
1. XtY - black coat male cat
2. XTY - yellow coat male cat.
Thus, The correct way to represent the genotype of a male cat with a black coat - XtY

Carbon-14 has 8 neutrons and 6 protons. When this radioisotope undergoes the radioactive decay process it becomes nitrogen-14.
The number of protons in nitrogen-14 is?
Answers
Answer:
Nº of protons = Atomic number → 7Nº of neutrons = Massic number - Atomic number → 14 - 6 = 7Explanation:
Probably, you will find it useful to know how to deduct this information for any other isotope.
To interpreter the representation of an isotope, you need to know that the symbol representing the isotopes is the same as the chemical element. The representation also includes a superior number that indicates the massic number, and an inferior number that indicates the atomic number.
Isotope representation ⇒ ⁰ X ₙ
Where
X is the element o is the massic number, which is defined as the sum of the number of protons and the number of neutrons. n is the atomic number, which is the number of protons.(Note: You can also find the O symbol as m symbol. Both represent the same massic number)
When protons, neutrons, and electrons get together to form an atom, they lose part of their mass as energy. This is why the atomic weight is slightly inferior to the sum of masses.
In the periodic table, there is only one value of atomic mass, which belongs to the media mass of isotopes pondered by their abundance in nature.
So, what you need to know is that
Nº of protons = Atomic number → nNº of neutrons = Massic number - Atomic number → o - n (or m - n)Nº of Electrons = Nº of protons = Atomic number → nCarbon-14 forms in the atmosphere, it is radioactive and unstable. When they emit an electron and an antineutrino, they become Nitrogen-14.
Isotope representation ⇒ ¹⁴ C ₆
Massic number = 14Atomic number = 6So, from this information we can assume that
Nº of protons = Atomic number → 6Nº of neutrons = Massic number - Atomic number → 14 - 6 = 8 Nº of Electrons = Nº of protons = Atomic number → 6So, from this information we can assume that
Massic number = 14Atomic number = 6The same reasoning can be used to determine the number of protons and neutrons of nitrogen-14.
Isotope representation ⇒ ¹⁴ N ₇
Massic number = 14Atomic number = 7So, from this information, we can assume that
Nº of protons = Atomic number → 7Nº of neutrons = Massic number - Atomic number → 14 - 6 = 7 Nº of Electrons = Nº of protons = Atomic number → 7

O a. That migrating songbirds are better served by the farmer's coffee plantation
ob. That coffee beans have been grown under organic conditions.
Oc. That coffee quality is the best possible.
O d. That social equity has been improved for these farmers.
Answers
The correct answer is C. That coffee quality is the best possible.
Explanation
A cooperative is a term that refers to a society made up of several individuals who group for the common benefit of its members. These associations are organized democratically and are administered according to the agreement established by their partners. For example, in this case, the coffee producers formed a cooperative to sell their products directly to consumers and eliminate intermediaries. In addition, they were accredited with a social certification by an accredited agency, which supports their products by indicating to consumers that their coffee is of the best quality. Therefore, the correct answer is C. That coffee quality is the best possible.
Consider two pure-breeding lines of grapes, P1 and P2. The average diameter of P1 grapes is 1.2 cm and the variance is 0.30 cm2. The average diameter of P2 grapes is 1.6 cm and the variance is 0.56 cm2. The two pure-breeding lines are crossed to produce F1 progeny. Based on this description, which of the following statements is false?
a) VG for F1 is > 0
b) VP for P1 < VG for P2
c) VE for F1 is > 0
d) VG for P1 = 0
e) VG for P2 = 0
Answers
Answer:
a)
Explanation:
From the given information:
The avg diameters:
For P1 grapes =1.2 cm
For P2 grapes = 1.6 cm
Their vairance is also given as follows:
For P1 = 0.30 cm²
For P2 = 0.56 cm²
Recall that:
the phenotypic variance VP = genetic variance (VG) + environmental variance VE
As stated that P1 and P2 lines are pure breeding lines, which means that the diameter of the seed in F1 was around halfway between the two parents' and the difference in the F1 was close to the parents'.
This implies that, provided the parent lines exist as pure breeding;
The genetic variation would be absent, indicating that VG is zero.
∴
VP = VE and VG = 0
Now, averaging the results of two pure breeding lines, we have:
[tex]V_E = \Big (\dfrac{0.30 + 0.56}{2} \Big) \\ \\ V_E = \dfrac{0.86}{2} \\ \\ V_E = 0.43 \ cm^2[/tex]
The formula used in estimating F1 genetic variance can be expressed as:
VP = VG + VE
Recall that
VE = VP = 0.43 cm²
∴
0.43 = VG + 0.43
VG = 0.43 - 0.43
VG = 0
Thus, The statement that is false is in Option a.
VG for F1 is > 0

One conclusion drawn from the experiment was that life span differences were independent of reproductive investment. If that is the case, then which of the following statements is true? Females that exhibited catch-up growth and produced many eggs had longer life spans than females that exhibited catch-up growth and produced few eggs. Females that exhibited catch-up growth and produced few eggs had longer life spans than females that exhibited catch-up growth and produced many eggs. Females that exhibited slowed growth and produced many eggs had longer life spans than females that exhibited slowed growth and produced few eggs. Females that exhibited slowed growth and produced few eggs had longer life spans than females that exhibited slowed growth and produced many eggs. Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Answers
Answer:
The correct answer is - Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Explanation:
According to the question, the life span differences were independent of reproductive investment, on the basis of this experiment, it is clear that the sexual gametes or egg which is a reproductive investment are independent of the lifespan of a female.
The life span of females could be slow growing or not but it will not affect the production of the gametes or eggs. Eggs production is dependent upon hormones produced.

The theory of E.O. Wilson's theory of Island Biogeography was originally developed as island biogeography, to explain species richness of actual islands, surrounded by water.
It proposes that the number of species found in an undisturbed environment is determined by immigration and emigration. According to him, the species richness will be the same if this island will have an equal number of the immigration and extinction or emigration of species.
