Question

In pea plants, the gene for the color of the seed has two alleles. In the following Punnett square shown below, the dominant allele (Y) represents yellow and the recessive allele (y) represents green.
Based on the Punnett square, what percentage of offspring would be expected to have yellow seeds?

Answer 1

Based on the punnett square, 100% of offspring would be expected to have yellow seeds (YY or Yy).

What is a punnet square?

A punnet square is a graphical representation used to determine the probability of an offspring expressing a particular genotype.

According to this question, in pea plants, the gene for the color of the seed has two alleles. However;

• the dominant allele (Y) represents yellow the recessive allele (y) represents green.

In the punnet square shown above, a pea plant with genotype YY is crossed with another pea plant with genotype Yy.

The following offsprings will be produced:

• YY
• YY
• Yy
• Yy

All the above offsprings have a dominant phenotype, hence, 100% of offspring would be expected to have yellow seeds (YY or Yy).
