Question

Activity #3: Do a dihybrid cross between a pea plant with purple flowers (Pp) and yellow seeds (Yy) PpYy What are the gametes produced by the plant: Draw a punnett square of the cross. What are the genotypic and phenotypic results?

Answer 1

3 Hese, p’allele is responsible for purple flower color and is dominant and 'p allele is recessive allele responsible for cohite flower color Also, 'Y' allele is dominont and is responsible for yellow seeds and 'y' is the corresponding recessive allele responsible for green seed color. Genotypes of given porrents > PpYy and PpYy . - Gametes - produced by these plants are:
