Question

A round green seeded plant (RRyy) is crossed to a wrinkled yellow (rrYY) seeded plant. Find
out phenotypes and genotypes in f1 and f2 genration with the help of a cross.​

Answer 1

Answer:

phenotypes: round yellow (4)

round green (2)

wrinkled yellow (2)

wrinkled green (1)

Explanation:

parents = RRyy , rrYY

F1 generation = RrYy( 4 round yellow seeded plants)

F2 generation=

RRYY (1 round yellow seeded)

RrYy (4 round yellow seeded)

RrYY (2 round yellow seeded)

RRYy (2 round yellow seeded)

rryy (1 wrinkled green seeded)

rrYY (1 wrinkled yellow seeded)

rrYy (2 wrinkled yellow seeded)

RRyy (1 round green seeded)

Rryy (2 round green seeded)

phenotypic ratio = 4:2:2:1

genotypic ratio = 1:2:1:2:4:2:1:2:1
