Question

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

Explanation:

A phenotype is the observable physical or biochemical characteristics of an organism. In a Punnett square, the phenotype ratio refers to the proportion of offspring that display a particular observable trait. It is not about alleles (alternative forms of a gene) in genes (which would be genotype - related in part, but not phenotype) or the number of genes or alleles.

Answer:

the fraction of possible offspring that can be observed to have a trait
