A botanist has acquired a group of pea plants. All of the pea plants have yellow pea pods (the recessive form of this trait) exc
Mekhanik [1.2K]

Answer:

Hetezygous

Explanation:

<em>The genotype of the initial green pod plant would be heterozygous.</em>

Let pea pod color be represented by C (c) alleles.

First, let us assume that the genotype of the green pea pod plant is homozygous dominant, CC. This was crossed with homozygous recessive, cc.

           CC   x   cc

      Cc   Cc   Cc   Cc

<u>All the progeny will have Cc genotype with phenotypically green color. </u><u>This is in contrast to the result obtained from the test cross in the illustration, hence the genotype of the initial green pea pod plant cannot be homozygous dominant.</u>

Now, let us assume that the genotype is Heterozygous, Cc.

       Cc   x   cc

 Cc   Cc   cc   cc

<u>50% of the progeny has Cc genotype with phenotypically green color while the remaining 50% has cc genotype with phenotypically yellow color. </u><u>This is consistent with the result from the illustration.</u>

Hence, the genotype of the initial green pea pod plant is heterozygous.

Which statement describes the offspring of the Fı generation when crossing a pea plant that is true breeding for green seeds wit
alukav5142 [94]

The offspring will inherit one allele from each parent.

<h3><u>Explanation</u>:</h3>

The genetic crossing experiments lead to the formation of different hybrids which has several characters unlike their parents. Here the parents are homozygous.

One of the parent is homozygous yellow with respect to seed colour. So genetic combination of the parent will be YY.

The other parent is homozygous green with respect to seed color. So genetic combination of the parent will be yy.

Now as they are crossed the offsprings will have genetic combination of Yy.

This is seen that the offsprings carry one allele from both the parents.
