Mitosis and meiosis are the two ways by which cells reproduce. As a result, they share several steps in their respective processes. Meiosis adds another division and a step that mixes the genetic material, but in both cases the cell must duplicate its DNA, pull it apart into two sets, place the sets on each end of itself, and then divide down the middle. Both mitosis and meiosis produce fresh new cells based on their parent cells' genes.
Answer:
0%
Explanation:
Achondroplasia is an autosomal dominant disorder that is expressed in both homozygous and heterozygous dominant genotypes. Since two affected parents have a normal girl child, both the parents should be heterozygous carrier for the disease. Let's assume that the dominant allele "A" is responsible for the disease. Genotype of both the parents of the girl would be "Aa". The genotype of girl with normal stature is "aa". Genotype of her normal partner is "aa".
A cross betwee aa X aa would get all the progeny with "aa" genotype. Therefore, all of their children would have normal stature and there is 0% probability for them to have a child with achondroplasia.
I would choose the option D.
D. It remains tightly coiled at the G1 phase.
