Question

Which is dominant - Round or wrinkled performed seed shape?

Answer 1

*Gregor Mendel, conducted hybridisation experiments on garden peas for seven years (1856-1863) and proposed the laws of inheritance in living organisms.

*He selected 14 true- breeding plant varieties, as pairs which were similar except for one character with contrasting traits. One such contrasting character is Round and wrinkled.

Seed Shape

Round(RR) * wrinkled(rr) {parental}

Round(Rr) {F1 generatio}

On selfing the F1 generation

Rr *Rr-the F2 generation consists of 3 round and one wrinkled seed shaped plants in the ratio 3:1(phenotypic ratio)

The genotypic ratio is 1(RR):2(Rr, Rr):1(rr)

From the above reasons, it is clear that round seed shape is dominant .
