A test cross must be performed to ascertain this plant's genotype. Yellow and green peas are the anticipated phenotypes of the progeny.
<h2>What is a test -cross?</h2>
To ascertain whether a progeny is homozygous or heterozygous for a given trait, an F1 progeny is crossed with a double (homozygous) recessive parental progeny (green pea). This is referred to as a test cross.
All of the hybrid's offspring will exhibit the dominant (yellow) phenotype if the mother is homozygous (YY) dominant.
Mother yellow pea (YY) x green pea (yy) - P generation
Y y - Gamete
Yy (yellow) , Yy (yellow) -F1 generation
If the mother is heterozygous dominant(Yy), then half of the offspring will exhibit the dominant phenotype and the other half will exhibit the recessive phenotype and the ratio should be 1:1.
Mother yellow pea (Yy) x green pea (yy) -P generation
Y, y y - Gamete
Yy (yellow) , yy (green) -F1 generation
Therefore, it is concluded from the above explanation that we have to perform a test-cross to know the genotype of the pea plant.
