Question

Answer 1

Answer:

• Mono refers to single and hybrid means mixed breed

•        Monohybrid cross is used to study the inheritance of a single pair of        alleles
• Used to study the dominance of genes
• Genotype ratio is 1:2:1

Answer 2

MONOHYBRID CROSS

• It is a cross between 2 pure organisms in order to study the inheritance of a single pair of contrasting character.
• It produces a phenotypic monohybrid ratio of 3:1 in F2 generation.
• It produces a genotypic ratio of 1:2:1 in F2 generation.
• Example : cross between tall and dwarf pee plant.

DIHYBRID CROSS

• It is a cross between 2 pure organisms in order to study the inheritance of 2 pairs of contrasting characters.
• It produces a phenotypic dihybrid ratio of 9:3:3:1 in F2 generation.
• It produces a genotypic ratio of 1:2:1:2:4:2:1:2:1.
• Example : cross of pea plants having round and yellow seeds and plants with wrinkled and green seeds.
