Question

What is monohybrid cross? Explain it with help of checker board give the genotypic and phenotypic ratio of the same

Answer 1

In this experiment, mendel brought about the cross between two pea plants with only one pair of contrasting character. This type of cross is called monohybrid cross.

Answer 2

                      Monohybrid cross

• All the zygotes get one R allele from the round embryo mother and one 'r' allele from the wrinkled seed parent.
• The 'R' allele is hostile to the 'r' allele; the phenotype of all the embryo was round.
• The phenotypic ratio in this case of Monohybrid cross is 1:1:1:1.
• In this experiment, Mendel brought about the cross between two pea plants with only one pair of contrasting character.
