Question

A plant with round seed is crossed with P1 generation RR winkled seeds.
i.what will be F1 generator?
ii.what will be phenotype?
iii. what will be genotype? ​

Answer 1

AnswEr:-

A cross between homozygous round seeds plant (RR) and homozygous wrinkled seeds plant (rr) will produce heterozygous (Rr) round seeds plants as F1 generation. The selfing of F1 will give F2 generation, where there will be 1 homozygous dominant round seed plant (RR), two heterozygous round seed plants (Rr) and 1 homozygous recessive wrinkled seed plant (rr). Phenotypically, there will be 3 round seed plants and 1 wrinkled seed plant. Hence, the correct answer is ‘3:1’
