bazaltina [42]

Answer:

(a) Gg × Gg; (b) genotypic = 1:2:1, phenotypic = 3:1

Explanation:

a) A cross between two gray seeded plants produces progeny with gray and white seeds in 3:1 ratio (302:98=3:1). This means that the parent plants are heterozygous and each has at least one recessive allele. If the allele "G" is responsible for gray seed and the allele "g" imparts white color to the seeds, the genotype of the heterozygous parents would be "Gg".  

b) A cross between two heterozygous gray seeded parents would produce progeny in following ratio:

Genotype ratio= 1 GG: 2 Gg: 1 gg

Phenotype ratio= 3 Gray: 1 white
