Question
Which of the following statements is FALSE?
Two individuals can be phenotypically identical yet have different genotypes for a given trait.
The phenotypic ratio of a cross between 2 plants that differ in two traits will always be 9:3:3:1 because of Mendel's laws.
A genotypic ratio of 1:2:1 and a phenotypic ratio of 3:1 would be the expected result of a monohybrid cross.
In autosomal dominant inheritance, males and females are equally affected, and the trait is typically seen in every generation.
Different species may differ in the number of chromosomes making up its genome.

Explanation / Answer
The phenotypic ratio of a cross between 2 plants that differ in two traits will always be 9:3:3:1 because of Mendel's laws.
. when the mutations are in one biological pathway, different ratios are seen. Usually there are only two or three phenotypes resulting from various combinations of the genotypic classes. Likewise, the F2 ratio is a modification of the 9:3:3:1 ratio, produced by grouping various components of the ratio.Epistasis is inferred when an allele of one gene masks expression of alleles of another gene and expresses its own phenotype instead.
