Question

if a pure tall plant is crossed with a dwarf plants the offspring will be​

Answer 1

Answer:

ANSWER

Height in pea plant is determined by two alleles, T and t. Pure tall plants have genotype TT while pure dwarf has genotype tt.

Here the F

1

generation has a genotype of Tt ( heterozygous ). Allele T is dominant over t and result in all the 'Tt' offspring as tall. Dominance is the condition in which the effect on the phenotype of one allele masks the contribution of a second allele at the same locus. The first allele is dominant and the second allele is recessive.

F

2

generation has offspring as TT, Tt and tt in the ration of 1:3:1. As we can see again, allele 'T' is dominant in case of the heterozygous condition.

So, the correct option is 'Dominance'.
