Answer:
3/16
Explanation:
Assuming that green, smooth peas are the dominant trait, as long as the gene has a dominant allele for colour or texture of the peas, the peas will be green or smooth respectively.
Hence wrinkled and yellow are the recessive traits. That must have a combination of 2 recessive alleles in the gene to have the recessive trait.
Assuming G is the allele for green and g is the allele coding for yellow peas, and W represents allele for smooth skin and w represents wrinkled skin,
The probability of 2 heterozygote parents (green and smooth) crossing with genotype of GgWw and GgWw to get offspring with Green and wrinkled peas of genotype G_ww (whereby _ represents either G or g), is 3/16 refer to diagram above.
