Vedclass · Answer

(A) In pea plants,tall $(T)$ is dominant over dwarf $(t)$,and axial flowers $(A)$ are dominant over terminal flowers $(a)$.The dwarf plant with terminal flowers must have the genotype $ttaa$.The offspring are tall with axial flowers $(TtAa)$ and tall with terminal flowers $(Ttaa)$ in a $1:1$ ratio.Since all offspring are tall $(Tt)$,the tall parent must be homozygous dominant $(TT)$.Since the offspring show a $1:1$ ratio for flower position (axial:terminal),the tall parent must be heterozygous for flower position $(Aa)$.Therefore,the cross is $TTAa 	imes ttaa$.

$A$ cross between two pea plants,tall with axial flowers and dwarf with terminal flowers,produced offspring that were tall with axial flowers and tall with terminal flowers in the ratio $1:1$. What will be the genotype of the parents?
