In pea plants, the allele for inflated pod seed, I, is dominant over the allele for constricted pod seed, i. The Punnett square shows a cross forthis trait. Which offspring will be homozygous dominant?

Answer:

II

Step-by-step explanation:

Since 'I' is the more dominant trait and 'homozygous dominate' is asking for the same dominante feature, II should be the answer

Hope this helps!

Answer:

Homozygous dominant will be the descendants presenting the "II" alleles. In the case of the punnet square shown above, it will be those that will be in the second square of the first column.

Step-by-step explanation:

Homozygous individuals are called “pure” as they are characterized by identical allele gene pairs. That is, the analogous alleles will produce only one type of gamete represented by the equal letters (AA, aa, BB, bb, VV, vv), with the uppercase being called the dominant, while the lowercase being the possessor of the recessive character.

In the case shown in the question above, we can state that the individuals who will be dominant hozygotes are those who will have the "II" alleles, since equal alleles represent homozygosis and uppercase letters represent the dominant alleles.
