In peas, yellow pea pods (Y) are dominant to green pea (y) pods. If a heterozygous dominant male is crossed with a heterozygous dominant female, what is the probability
that the offspring will be green?

In crossing heterozygous pea plants for the color of the pea pods trait, the probability of a offspring with the green pea pod is 25%.

Explanation:

Taking into account that the dominant trait is the yellow pea pod, and that both members of the parental generation are heterozygous (Yy):

Parental generation:

♂ Yy

♀ Yy

Making a Punnet's Square for this crossing:

Yy x Yy

Alleles    Y      y

Y            YY   Yy

y             Yy   yy

In the offspring, the phenotypic probabilities are :

The Yy:YY:yy ratio is 2:1:1

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
