What is a monohybrid and dihybrid cross?

Monohybrid and Dihybrid Cross

In genetics, monohybrid and dihybrid crosses are two types of genetic crosses used to study the inheritance of traits in offspring. These crosses involve the combination of alleles from two parent organisms to predict the phenotypic and genotypic ratios of their offspring.

Monohybrid Cross

Monohybrid cross is a genetic cross where the parents differ in only one trait. This type of cross involves the combination of alleles from two homologous chromosomes of a single gene. In a monohybrid cross, one parent is homozygous dominant (having two of the same dominant alleles) and the other parent is homozygous recessive (having two of the same recessive alleles).

Dihybrid Cross

Dihybrid cross is a genetic cross where the parents differ in two traits. This type of cross involves the combination of alleles from two different genes located on different chromosomes. In a dihybrid cross, both parents are heterozygous (having two different alleles) for two different genes, resulting in multiple possible combinations of alleles in the offspring.

What is the difference between a monohybrid and dihybrid cross? Monohybrid is an homoztgous hybridization with dominant genotype while dihybrid cross is an hereozygous hybridization which occurs between alleles of different traits.
