Answer:

50 percent

Explanation:

Luisvaschettoidn

Considering one heterozygous parent and a homo-zygous recessive parent, the probability of an offspring plant having a green (recessive) phenotype is 50 percent (50%).

What is a Punnett square?

A Punnet square is a diagram used to represent the gametic combination that will give rise to a given genotype/phenotype.

  • In this case, one parent is heterozygous (genotype Yy, carrier of the recessive allele), whereas the other parent is recessive homo-zygous (genotype yy).

  • Here, the Punnett square is equal to:

              Y              y

y        1/4 Yy      1/4 yy

y        1/4 Yy      1/4 yy

In conclusion, considering one heterozygous parent and a homo-zygous recessive parent, the probability of an offspring plant having a green (recessive) phenotype is 50 percent (50%).
