In peas, yellow seed color (y) is dominant to green seed color (y). a homozygous green pea plant is crossed with a heterozygous yellow pea plant. what is the predicted phenotypic ratio of the offspring

2: 2 or 1:1

Explanation:

It is given that the yellow seed color is dominant over green seed color. The genotype of homozygous green pea plant and heterozygous yellow pea plants are “yy” and “Yy” respectively.  

The following punnet table represents the cross between “yy” and “Yy”

yy

YYyYy

yyyyy

The genotypic ration is 2Yy :2yy

Yy represents heterozygous yellow pea plant

yy represents homozygous green pea plant  

yellow pea plant : green pea plant is equal to 2: 2 or 1:1

what are the choices?
