Although ascospores are produced by mitotic division, none of the spores develop into fungi that are identical to either parental hyphae. What is the BEST explanation for this observation? A.

The spores inherit half their genes from each parent.

B.

The spores inherit haploid nuclei from their parents.

C.

The spores inherit mutations as a result of meiosis.

D.

The spores inherit mutations as a result of mitosis.

A

Explanation:

The correct answer would be that the spores inherit half of their genes from each parent.

The ascospores start their journey through the fusion of 2 haploid nuclei (karyogamy) to form a diploid zygote nucleus. The zygote nucleus develops and then divides by meiosis to produce 4 haploid daughter cells. Each daughter cell then divides mitotically, making it eight haploid nuclei at the end.

Hence, each spore inherits half of its gene from different nuclei.

The correct option is A.

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's
