Answer:
The heritability of type 1 diabetes is likely high, indicating that genetics plays a larger role in the development of type 1 diabetes than the environment.
Explanation:
Identical twins are formed when a single zygote separates into two embryos after the process of fertilization. Hence, these twins arise from the same egg and sperm.
Fraternal twins arise when two different sperms fertilize two eggs at the same time.
Hence, we can say that the genotype of the identical twins is similar.
The results from concordance data prove that genetics play a higher role in type 1 diabetes.
Answer:
It wouldn't be able to migrate to the cell's poles.
Explanation:
During anaphase, microtubules attach the chromosome's centromeres and start dragging them towards the poles of the cell. In mitosis, this causes the separation of both sister chromatids for each chromosome, and each chromatid migrates to a different pole. In meiosis, first each homologous chromosome is separated by the same process, and then the sister chromatids are separated during anaphase II. If a chromosome doesn't have centromeres, microtubules are unable to attach the chromosomes, and so the separation of either sister chromatids or homologous chromosomes can't take place.
<span>T he type of selection that favored progressively larger brain size in human evolution is
</span>directional selection. Directional selection is a type of natural selection (besides stabilizing selection, disruptive selection, kin selection,..)<span> in which an extreme phenotype is favored over other phenotypes. Because progressively larger brain size is an extreme phenotype this is a directional selection.</span>
