Question

What will happen if pure homozygous pea plant cross up to F2 generations by focusing the one contrast character?​

Answer 1

Answer:

the phenotypic ratio is 3:1 and genotypic ratio is 1:2:1

Answer 2

When true-breeding, or homozygous, people that vary for a positive trait are crossed, all the offspring could be heterozygous for that trait.

If the tendencies are inherited as dominant and recessive, the F1 offspring will all showcase the identical phenotype because the figure homozygous for the dominant trait.

The F1​ era has the genotype Tt that is why all of the plant life are tall in top for the reason that they all include the allele for tall top (dominant allele).In the presence of a dominant allele, the recessive allele isn't expressed while all of the plant life have tall top. But while the plant life of this era are self-crossed we get the subsequent genotypes withinside the new era: TT :Tt: tt withinside the ratio 1:2:1. Hence 25% of the plant life have each the alleles because the recessive allele. When the dominant allele is absent the recessive allele is expressed withinside the plant is brief in top. The recessive allele became suppressed withinside the F1​ era however expressed withinside the F2​ era.
