Question :By using Punnett square depict the genotypes and phenotypes of test crosses (where green pod colour (G) is dominant over yellow pod colour (g)) in Garden pea with unknown genotype.

The correct answer is –

In this example, the unknown genotype is crossed with a homozygous recessive (gg) individual. The dominant allele G represents green pod color, while the recessive allele g represents yellow pod color. The genotypes of the resulting offspring can be read from the boxes in the Punnett square.

The possible genotypes of the offspring are GG and Gg. GG individuals will have green pods, while Gg individuals will also have green pods because the G allele is dominant. Only gg individuals will have yellow pods.

The phenotype ratio of the offspring from this test cross will be 1:1, meaning half of the offspring will have green pods and half will have yellow pods. The genotype ratio will be 1:1, meaning half of the offspring will be homozygous dominant (GG) and half will be heterozygous (Gg)
