Answer:
The extinction of a large number of species within a relatively short period of geological time.
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 <u>100%</u>. If an offspring from this cross mates with a pp, the possibility of homozygous dominant genotype for the flowers will be <u>50%</u>.
<em>The dominant allele for the flower is P, and the recessive allele for the flower is p. </em>
<em>The possible genotypes of the purple flower is; PP or Pp.</em>
<em>The possible genotype of the white flower is; pp.</em>
