What Phenotype ratio is obtained when individuals heterozygous for two traits are crossed?

Answer 1

If Dominant Trait is "X" and recessive is "x"

Then You will get

1 - XX
2 - Xx
and 1 - xx

for a 1:2:1. Genotype ratio is 3:1 For the dominant trait.

Answer 2

If you're referring to a dihybrid cross that involves traits that have complete dominance and the two parents are completely heterozygous for both traits, the phenotypic ratio of the expected offspring would be: 9:3:3:1.

Answer 3

If it's a trait with simple dominance, then the offspring are 3 of the dominant phenotype to 1 of the recessive phenotype... 3:1.

If it's a trait with incomplete or codominance, then it's 1:2:1.

Answer 4

3:1 only one offspring will be homozygous recessive
