Question

During meiosis, the alleles of the parental pair separate or segregated from each other. How many allele(s) is/are then transmitted to a gamete?

Answer 1

If nondisjunction occurs during anaphase II of meiosis II, it means that at least one pair of sister chromatids did not separate. In this scenario, two cells will have the normal haploid number of chromosomes. Additionally, one cell will have an extra chromosome (n + 1) and one will be missing a chromosome (n - 1).

Answer 2

Answer:

each homologue of a homologous pair of chromosome has one allele. When the two homologous chromosomes of a pair separate, alleles separate and finally only one allele goes to each gamete.
