Question

a yellow seed pea plant (heterozygous dominant) is crossed with a recessive green pea plant to make f1 offspring.

Answer 1

The F1 offsprings obtained are yellow seed pea plants and green seed pea plants in the ratio of 1:1.

The yellow seed color in the pea plant is a dominant character and the green seed pea color is a recessive character.

When a heterozygous yellow seed pea plant with the genotype Yy is crossed with a recessive green seed pea plant with the genotype yy.

The probability offsprings of the F1 generation are 50% yellow seed and  50% green seed pea plant. so the phenotypic and genotypic ratio is 1:1.

This method is the test cross used to determine the genotype of the individual organism for the particular character.

Thus if we cross heterozygous yellow seed pea plant with the recessive parent the offsprings are yellow and green seed pea plants with a ratio of 1:1.
