What is meant by a phenotype ratio in a Punnett square? (1 point)

Question

the fraction of possible offspring that contain a certain allele in their genes
the number of genes that are possible in offspring
the fraction of possible offspring that can be observed to have a trait
the number of alleles in possible offspring

Answer 1

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

In a Punnett square, the phenotype ratio refers to the ratio of different observable traits (phenotypes) that result from a genetic cross, based on the combination of alleles inherited from the parents.
