A cross between two green corn plants yields [tex]\frac{2}{3}[/tex] progeny that are green and [tex]\frac{1}{3}[/tex] progeny that are white. What is the genotype of the green progeny?

A. WW
B. Ww
C. ww
D. W (WW and Ww)

Answer :

Final answer:

A cross between tow green corn plants yields 2/3 progeny that are green 1/3 progeny that are white, the genotype of the greenprogeny is c) ww.

Explanation:

The correct genotype of the green progeny in the cross between two green corn plants is ww. This is because the green progeny are the result of the offspring being homozygous recessive for the green color, which is represented by the genotype ww. When two green corn plants are crossed, they both carry the recessive allele for green color, leading to the expression of the green phenotype in the offspring.

In conclusion, in this genetic cross, the green corn plants yield progeny with the genotype ww, showing the expression of the green color due to homozygosity for the recessive allele.

Therefore, option c) ww is the correct genotype.
