Vedclass · Answer

(A) In pea plants,the allele for tallness $(T)$ is dominant over the allele for dwarfness $(t)$.$A$ heterozygous tall plant has the genotype $Tt$.$A$ dwarf plant must have the homozygous recessive genotype $tt$.When performing a test cross between $Tt$ and $tt$:$Tt 	imes tt ightarrow$ Gametes produced are $T, t$ from the heterozygous parent and $t$ from the dwarf parent.The resulting offspring genotypes are $Tt$ (tall) and $tt$ (dwarf) in a ratio of $1:1$.Therefore,the progeny shows $1$ Tall : $1$ dwarf.

$A$ heterozygous tall pea plant was crossed with a dwarf pea plant. The progeny of the cross shows . . . . . . .
