Vedclass · Answer

(A) The genotype of the heterozygous tall and violet flowered pea plant is $TtRr$.When $TtRr$ is selfed $(TtRr 	imes TtRr)$,the phenotypic ratio of the offspring is $9:3:3:1$.The genotypic ratio for the double heterozygous condition $(TtRr)$ in a dihybrid cross is $4/16$ (or $1/4$ of the total population).Given the total number of seeds is $512$.The number of seeds heterozygous for both traits $(TtRr)$ = $512 	imes (4/16) = 512 	imes (1/4) = 128$.

Heterozygous tall and violet flowered pea plants were selfed and total $512$ seeds are collected. What will be the total number of seeds that are heterozygous for both traits?
