|
a monohybrid cross is performed for one generation, wheres a dihybrid cross is performed for two generations
|
|
|
a dihybrid cross involves organisms that are heterozygous for two characters and a monohybrid only one
|
|
|
a monohybrid cross results in a 9:3:3:1 ratio whereas a dihybrid cross gives a 3:1 ratio
|
|
|
a monohybrid cross involves a single parents, whereas a dihybrid cross involves two parents
|
Detailed explanation-1: -A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents. A dihybrid cross involves organisms that are heterozygous for two characters that are being studied, and a monohybrid cross involves organisms that are heterozygous for only one character being studied.
Detailed explanation-2: -A monohybrid cross is defined as the cross happening in the F1 generation offspring of parents differing in one trait only. A dihybrid cross is a cross happens F1 generation offspring of differing in two traits.
Detailed explanation-3: -A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus.
Detailed explanation-4: -A monohybrid cross produces a single progeny, whereas a dihybrid cross produces two progeny. one.
Detailed explanation-5: -A Dihybrid cross is a cross between two different genes having different characters. Dihybrid test crossing is the cross in which one parent from F1 generation having heterozygous condition gets crossed with a parent which is double homozygous and recessive in nature. They are allowed to fertilize with each other.
