Q. The number of plants found similar to phenotype and genotypes, respectively in a total of plants in progeny of a Mendelian dihybrid cross:
Solution:
Dihybrid cross- It is a cross between individuals possessing homozygous dominant alleles and one parent having a homozygous recessive allele. Mendel crossed pea plants differing in two characters (dihybrid cross) to verify the results of monohybrid crosses. This helped him to understand the inheritance of two pairs of factors at a time.
In a dihybrid cross, Punnett square helps in identifying the genotypes and the phenotypes of plants in a cross.
Below is the table which best describes the Punnett square.
In Dihybrid cross the phenotypic ratio of F2 generation = .
Among 16 progeny 9 carries phenotype as F1 generation .
In Dihybrid cross the genotypic ratio of F2 generation = .
Among progeny carries genenotype as F1 generation .
