Question

which of the following is true about punnett squares? a they can show the possible genetic combinations in the offspring. b gametes are unimportant for a punnet square. c they cannot predict the possible phenotypes of the offspring.

Explanation:

A Punnett square is a tool in genetics. It takes the gametes (sex cells) of parents. Then, it combines them. This shows all possible genetic combinations (genotypes) in offspring. Gametes are crucial as they carry genetic info. Also, from genotypes, we can predict phenotypes (observable traits). So, option a is correct.

Answer:

A. They can show the possible genetic combinations in the offspring.
