Question

Look at the Punnett square above. Mom and dad are both heterozygous (have 1 dominant and 1 recessive gene).

What is the phenotype ratio (physical trait) for this probability outcome for the offspring?

3_____: 1______

Answer 1

75% 25%. If this is what you were looking for

Answer 2

In the given cross, the phenotype ratio (physical trait) for this probability outcome for the offspring -

3 dominant traits (Hh or HH):1 recessive trait (hh)

Heterozygous parents cross

In the given cross of parents where mom and dad both have a heterozygous genotype which means both have one dominant allele H and one recessive allele h.

The gametes will be the same for both H and E and that will form one wild type HH that is dominant and two heterozygous which is also dominant phenotype and only one recessive trait or phenotype which means the probability ratio would be 3:1 for dominant: recessive.
