Question

1. a basketball player develops speed and power as a result of practice. why will this athletic ability not be passed on to her offspring?

a. muscle cells do not carry genetic information
b. mutations that occur in body cells are not inherited
c. gametes do not carry completes sets of genetic information
d. base sequences in dna are not affected by this activity

1. hereditary information for most traits is generally located in

Explanation:

The question is about why a trait (speed and power developed through practice) isn't passed to offspring. In genetics, only genetic information in gametes (reproductive cells) is passed to offspring. Muscle cells (a somatic/body - cell type) don't carry genetic information for inheritance. Mutations in body cells (somatic mutations) aren't inherited. Gametes carry genetic information, but the development of speed and power through practice doesn't change the base sequences in DNA in a heritable way.

Answer:

a. Muscle cells do not carry genetic information; b. Mutations that occur in body cells are not inherited; c. Gametes do not carry complete sets of genetic information (incorrect as gametes carry half - sets which combine during fertilization); d. Base sequences in DNA are not affected by this activity (while true, it's not the most direct reason related to cell - type and inheritance as a and b). The most relevant are a and b. But if we consider the options in terms of cell - type and inheritance mechanism: Muscle cells (a) are somatic and don't pass info, mutations in body cells (b) (somatic mutations) aren't inherited. So the answer is a and b.
