Cuando una celula se va a dividir, la cromatina se contrae y compacta y forma estructuras como la que se ve al lado. Diga qué nombre reciben estas estructuras y cuantas hay en una célula humana
Answer:
cromosomas
Explanation:
Los cromosomas son moléculas lineales de ADN que contienen parte o todo el material genético de un organismo. El ciclo celular se divide en dos etapas: 1-interfase o etapa de 'no división' y 2-división celular. Durante la interfase, las fibras de cromatina no poseen un grado de condensación suficiente como para hablar de cromosomas. Durante la primera etapa de división celular (es decir, durante la profase), las fibras de cromatina se condensan para formar estructuras compactas conocidas como 'cromosomas' los cuales serán distribuidos entre células hijas. Las células somáticas de los seres humanos son diploides (2n = 46 cromosomas), esto significa que contienen 23 pares de cromosomas homólogos los cuales se alinean durante la metafase de la mitosis en la placa ecuatorial de la célula para ser distribuidos equitativamente entre células hijas durante las fases posteriores del ciclo celular (anafase, telofase y citocinesis). Por otra parte, las células germinales o gametos (espermatozoides masculinos y los óvulos femeninos) son haploides (n = 23 cromosomas) las cuales contienen un sólo set completo de cromosomas.

Question:What does codominance mean in genetics?
1.Both alleles are dominant and are expressed.
2.Both alleles are recessive and are not expressed.
3.The alleles are neither dominant nor recessive.
4.Each allele is both dominant and recessive.
Option 1
that can give nice mixtures of colors in flowers, like alleles for white and red are expressed, and mixed to pink seen by the human eye
Codominance mean in genetics is the alleles that are neither dominant nor recessive. So, the correct option is (C).
What is Codominance?Codominance is a type of inheritance in which two alleles of the same gene are expressed differently to produce different types of traits in an individual.
It is a heterozygous condition in which both alleles at a single gene locus are fully expressed in the phenotype. These alleles showing an independent effect are called codominant alleles.
In codominance, neither phenotype is completely dominant nor recessive. For example, the ABO type of blood group.
The gene which control human ABO blood groups has three alleles, not just two:
[tex]I^A[/tex] and [tex]I^B[/tex]are not dominant over one another. These are dominant over [tex]I^O[/tex].
Thus, Codominance mean in genetics is the alleles that are neither dominant nor recessive. So, the correct option is (C).

Why do structural similarities between living things point to common ancestry?
Explanation:
Comparative anatomy is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies. Both provide evidence for evolution. ... The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.

What are two ways that meiosis contributes to genetic variation? How do these two ways lead to variation?
Answer:
During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.Hope this is fine for you!!
