In a breeding program a cross was made between two true breeding cow-pea types: one with round seeds and the other with wrinkled seed. If roundness is dominant why wrinkleness is recessive, in the first filial generation all the seeds produced will be
Owing to the dominance of roundness, the crossing of the two seeds regularly would see all the offsprings having mixed genes but will be round.
Let RR = round seeds while RR = wrinkled seed
In the first filial generation, if we cross RR x rr
We'll have Rr, Rr, Rr, Rr
Remember that RR is dominant while rr is recessive
Therefore, All the four offsprings will be Dominant Round i.e 100% Round
