Mendel crossed purebred yellow seeds with purebred greenseeds. Then he self ferilised the F1 progeny to obtain the F2. The statistic analysis of the F2 showed that... (more than one answer might be right)

• 100% of the F1 and 75% of the F2 were yellow.

• All seed were yellow.

• 50% of F1 and 75% of F2 were yellow.

• Green colour disappeared in the F1 but reappeared in F2

What does first Mendel's laws state?

• When crossing two purebred individuals the phenotype of the offspring is homogeneus and corresponds to the dominant trait.

• When crossing two purebred individuals the phenotype of the offspring is homogeneus and corresponds to the recessive trait.

• When crossing two hybrids showing the dominant phenotype, the recessive trait reappears in the offspring.

• The offspring will look like parentals.
