Question

When two pea plants heterozygous for violet flower color were crossed with each
other; then 450 offsprings having violet flower color were obtained.
Select the correct statement (s) regarding the given cross.
When the heterozygos for purple floral color were hybridized between two pea
plants, 450 violet flowers were obtained.
Choose the correct statement / statements with respect to the given
hybridization​

Answer 1

Answer:

Test cross is the cross which is done to find out the genotype of parents. Suppose the genotype of a pea plant parent with violet flowers is CC and that of homozygous recessive parent is cc. If the F

hybrid had yielded 50% violet flowers and 50% white flowers it is a clear case of heterozygous parents which means that the genotypes of parents are Cc and cc.

Genotype Cc (Violet flowers) X cc (white flowers)

Gametes C and c c and c

Gametes C c

c Cc cc

c Cc cc

Thus, 50% offsprings are with violet flowers and 50% with white flowers.
