in Mendel 's experiment with garden pea, round seed shape RR was dominant over wrinkled seeds rr, yellow cotyledon YY was dominant over green Cotyledon yu. what are the expected phenotypes in the F2 generation of the cross RRYY*rryy??

hey mate!!
______________________________________________________________
when we cross RRYY x rryy
then F1 hybrid obtaind = RrYy
while selfing RrYy you willget....
phenotypic ratio = 9:3:3:1
and genotypic ratio = 1:2:1:2:4:2:1:2:1

options are - 1. only round seeds with green Cotyledon 2.only wrinkled seeds with yellow Cotyledon 3.only wrinkled seeds with green Cotyledon 4.Round seeds with yellow Cotyledon, and wrinkled seeds with yellow Cotyledons
yami then in Question it must be for f1 generation....
you have asked for f2 generation
for F1 generation answer should be.. ROUND SEEDS WITH YELLOW COTYLEDONS
no no... there is F2 generation.. and ans is 4 ... I think, there ' Only' is written in above three statements and in F2 generation we found both round seed wd yellow cotldn and wrinkled wd yellow ....
so in this way.. 4th is Crct... I think so...
