In pea plants, the allele for green pods is dominant over the allele for yellow pods. A plant that is heterozygous for the green pod is crossed with a plant that has yellow pods.

Mendel's first law of Segregation of Gametes says that "The alleles of a given locus segregate into separate gametes during meiosis"

Explanation:

The two alleles of a gene pair separate from each other during the process of meiosis and each gamete have an equal probability of producing either allele of the gene.

One parent pea plant is homozygous for inflated pods and green (suppose GGII) which is dominant in nature. Another parent pea plant is homozygous for deflated pods and yellow (suppose ggii) which is recessive in nature.

•) Then both the homozygous parent plants (GGII and ggii) which are dominated and recessive are crossed.

•) The gametes which will be obtained are GI and gi.

•) The resultant progeny is heterozygous with dominant traits GgIi.
