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

Question

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

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 relative numbers of offspring with different observable characteristics (phenotypes) that result from a genetic cross.
