Males always inherit their Y chromosomes from their fathers.

Alterations/modification to chromosome structure cannot negatively influence organismal survival as long as all of the genes in the genome are retained.

A man (Greg; normal vision) and a woman (Stacy; normal vision) decide to have a baby. Stacy happens to have a color-blind father and a mother with normal vision (color-blindness is X-linked recessive). What proportion of Greg and Stacy’s offspring would we expect to be colorblind? What proportion would we expect to be carriers?

Explain how Barr bodies influence patterns of phenotypic expression (e.g. how something looks).

Select all option below that could be considered a phenotypic character.

Animals tolerate polyploidy better than plants.

Each species has a characteristic number of chromosomes.

The parents you inherited a gene from can influence the expression of that gene.

A client is prescribed a new medication, haloperidol (Haldol), for chronic schizophrenia. Assessment reveals muscular rigidity, hyperthermia, and an altered level of consciousness. The nurse identifies these findings as suggestive of which condition?
