Question

What is meant by a phenotype ratio in a Punnett square?(1 point) Responses the number of alleles in possible offspring the number of alleles in possible offspring the fraction of possible offspring that can be observed to have a trait the fraction of possible offspring that can be observed to have a trait the fraction of possible offspring that contain a certain allele in their genes the fraction of possible offspring that contain a certain allele in their genes the number of genes that are possible in offspring the number of genes that are possible in offspring

Answer 1

The correct response is: the fraction of possible offspring that can be observed to have a trait.

In a Punnett square, the phenotype ratio represents the proportion of different observable traits (phenotypes) that can be expected in the offspring based on the genetic combinations of the parents.
