What is the phenotypic ratio of monohybrid cross

A monohybrid cross results in a phenotypic ratio of 3:1 (dominant to recessive), and a genotypic ratio of 1:2:1 (homozygous dominant to heterozygous to homozygous recessive).

What is a monohybrid cross?

A monohybrid cross is a genetic mix between two individuals with homozygous genotypes which result in an opposite phenotype.

Give an example of a monohybrid cross.

Breeding a long-stemmed pea plant with a short-stemmed pea plant is an example of a monohybrid cross. A cross between the two creates heterozygous offspring.

Monohybrid cross example

An example of a monohybrid cross is the cross between tall pea plants and dwarf pea plants. An example of a dihybrid cross is the cross between pea plants with yellow round and green wrinkled seeds.

Is a Punnett square a monohybrid cross?

The Punnett square is named after its developer, British geneticist Reginald C. Punnett. In a monohybrid cross, such as the one in Figure below, the Punnett square shows every possible combination when combining one maternal (mother) allele with one paternal (father) allele.

What is monohybrid cross Class 10?

Monohybrid cross is a cross between parents differing in only one trait or in which only one trait is being considered. Dihybrid cross is a cross between parents in which two pairs of contrasting characters are studied simultaneously for the inheritance pattern.

What is a Monohybrid test cross?

A monohybrid test cross is the process by which you cross two organisms that are heterozygous for a given trait. In such a case, by the law of dominance and by using the Punnett square, you know that the proportion of the offspring produced will be 25% homozygous dominant, 50% heterozygous and 25% homozygous recessive.

How many traits are involved in a monohybrid cross?

In a monohybrid cross, only one trait is examined.

What is the genotype of monohybrid cross?

A monohybrid cross results in a phenotypic ratio of 3:1 (dominant to recessive), and a genotypic ratio of 1:2:1 (homozygous dominant to heterozygous to homozygous recessive).

What is Monohybrid in biology?

a hybrid between two species that only have a difference of one gene. homozygous: of an organism in which both copies of a given gene have the same allele. heterozygous: of an organism which has two different alleles of a given gene.

What is Monohybrid ratio?

Monohybrid ratio is defined as the phenotypic ratio of different types of offsprings (dominant and recessive) obtained in F2 generation of a monohybrid cross. In monohybrid cross experiment the phenotype ratio for F2 generation is 3:1.
