Answer:

A) 1/256

Explanation:

Parent 1 : YyTtRrSs

Parent 2: YyTtRrSs

Probability of a YY offspring occurring in a cross between Yy and Yy = 1/4

Probability of a TT offspring occurring in a cross between Tt and Tt = 1/4

Probability of a RR offspring occurring in a cross between Rr and Rr = 1/4

Probability of a SS offspring occurring in a cross between Ss and Ss = 1/4

Total probability of YYTTRRSS =

1/4 * 1/4 * 1/4 * 1/4 = 1/256

Hence, 1/256 of offspring will be YYTTRRSS

Gray seed color in peas is dominant to white. Assume that Mendel conducted a series of experiments where plants with gray seeds

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
