Question

tabulate the cross between a pea plant with round seeds and another pea plant with wrinkled seeds. mention the type of plants obtained in F1 generation. write their phenotypic and genotypic ratios in F2 generation
CLASS 10 CH 9​

Answer 1

Answer:

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