A pea plant with genotype PP (purple flowers) mates with a plant with the genotype pp (white flowers). The dominant allele P codes for purple flowers. The possibility that the offspring will have purple flowers is . If an offspring from this cross mates with a pp, the possibility of homozygous dominant genotype for the flowers will be .

In the question, it is given that the purple flowers are dominant to the white flowers. The dominant allele for the flower is P, and the recessive allele for the flower is p.

So, the possible genotypes of the purple flower is - PP or Pp.

And, the possible genotype of the white flower is - pp.

The cross1 shows the cross between PP and pp.

The phenotype of all the offspring in the cross 1 is Purple, and the genotype is pp. Hence, the possibility of getting purple flowers in the progeny is 100%.

Homozygous dominant genotype is the condition, in which the plant's alleles are same and both are dominant.

The cross 2 shows the cross between Pp and pp:

The homozygous dominant genotype (PP) is 1 and the total number of progeny is 4. So, the probability of occurence of PP is 1/4 or 25%.

Hence, the first blank can be filled with 100% and the second blank can be filled with 25%.

The possibility that the offspring will have purple flowers is P . If an offspring from this cross mates with a pp, the possibility of a homozygous dominant genotype for the flowers will be. In the question, it's miles for the reason that the crimson flora are dominant to the white flora.

What phenotype could a plant with the genotype PP have?

P is dominant to p, so offspring with both the PP or Pp genotype can have the crimson-flower phenotype. Only offspring with the pp genotype can have the white-flower phenotype.And, the feasible genotype of the white flower is - pp.Cross1 indicates the pass among PP and pp.

The phenotype of all of the offspring withinside pass 1 is Purple, and the genotype is pp. Hence, the opportunity of having crimson flora withinside the progeny is 100%. Purebred dominant genotype is the condition, wherein the plant's alleles are identical and each are dominant.
The pass 2 indicates the pass among Pp and pp:The dominant genotype (PP) is 1 and the full variety of progeny is four. So, the opportunity of occurrence of PP is 1/four or 25%.Hence, the primary clean may be full of 100% and the second one clean may be full of 25%.
