Question

A cross was carried out between two pea plants showing the contrasting traits of heightofthe plant. The result ofthe cross showed50% ofparental characters.
(i) Work out the cross with the help of a punnett square.
(ii) Name the type of the cross carried out.

Answer 1

the cross was monohybrid cross b/w the deafness and the tallness

the cross show the ratio of genotype i.e 1:2:1

and phenotype 3:1

hope it will help you

Answer 2

Test cross in pea plants

Explanation:

• If the cross is carried out between a homozygous recessive organism and another organism showing the dominant phenotype and the organism showing the dominant phenotype has a heterozygous genotype for the trait then the resulting F1 generation will have half of the organisms of the dominant phenotype (i.e 50%) and the other half of the recessive phenotype. So, both the parental characters will be seen.
• The cross carried out is a test cross.
