Identify each of the following statements as true or false a

Identify each of the following statements as true or false (and remember to explain your answer). The age of the father is more important than the age of the mother in determining the number of nonpoint mutations (i.e.. base-pair substitutions) in a human child. The age of the father is more important than the age of the mother in determining the risk of trisomies (e.g.. Down syndrome) in a human child. Mitosis cannot occur in haploid cells because it requires pairs of homologous chromosomes to be present. Meiosis cannot occur in haploid cells because it requires pairs of homologous chromosomes to be present.

Solution

Answer:

9.

(a) True

The more the age of the father, more is the chance of transferring acquired mutations to the child by the father.

(b) False

Age of the is more important in determining the risk of trisomies. This is because, older the eggs, more is the chance of the egg suffering protein decay over time.

(c) False

Mitosis can take place in haploid cells.

(d) True

Pairing of homologous chromosomes is a necessary part of meiosis and cannot take place in haploid cells since homologs are absent.
