Question

what will be the phenotype of the F1 progeny plants when pure line pea plants having green seeds are crossed woth pure line pea plants having yellow seeds ​

Answer 1

Answer:

In an experiment, a cross is made between a homozygous plant with yellow round seeds(YYRR) is crossed with another homozygous plant with green wrinkled seeds(yyrr). In the F1 generation all progeny shows yellow round seeds(YyRr). In F1 progeny Yellow and round characters are expressed and wrinkled and green characters are not expressed. Here expressed character are dominant characters and not expressed characters are recessive characters. Mendel postulated, this explanation as Law of dominance. Due to this, all progeny in F1 are yellow round.
