If the the mother is homozygous recessive and the fathe is heterozygous?

For example, if one parent is homozygous dominant (WW) and the other is homozygous recessive (ww), then all their offspring will be heterozygous (Ww) and possess a widow's peak. If both parents are heterozygous (Ww), there is a 75% chance that any one of their offspring will have a widow's peak (see figure).

When crossing a homozygous recessive parent with a heterozygous parent what is the chance of getting an offspring with the homozygous recessive phenotype?

The answer is 50%.

Assume that the homozygous recessive trait is denoted by aa and the heterozygote is Aa.

What is the genotypic ratio if one parent is homozygous recessive and the other is heterozygous?

The expected genotype ratio when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive). When a phenotypic ratio of 2 : 1 is observed, there is probably a lethal allele.

Is heterozygous dominant over homozygous recessive?

The term “heterozygous” also refers to a pair of alleles. Unlike homozygous, being heterozygous means you have two different alleles. You inherited a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one.

When a homozygous dominant and a homozygous recessive are cross what percent of the offspring will be heterozygous?

25% of the heterozygous cross are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will always display the dominant trait (phenotype), because they are heterozygous.

What is the genotypic ratio of a homozygous dominant and homozygous recessive?

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 will be the genotypic ratio of the cross between RR and RR?

1 : 2 : 1.

What are homozygous dominant genotype?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

What is meant by homozygous and heterozygous?

Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent.

What's homozygous recessive?

Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele.

What is the chance of heterozygous parent passes on a recessive allele?

A person with a single gene disorder has a 50/50 chance of passing the mutated allele to a child who will become a carrier. If both parents have a heterozygous recessive mutation, their children will have a one-in-four chance of developing the disorder. The risk will be the same for every birth.

How do you know if its heterozygous or homozygous?

Because an organism has two sets of chromosomes, it usually only has two options to choose from when determining phenotype. If an organism has identical genes on both chromosomes, it is said to be homozygous. If the organism has two different alleles of the gene it is said to be heterozygous.

What happens when two homozygous organisms are crossed?

When true-breeding, or homozygous, individuals that differ for a certain trait are crossed, all of the offspring will be heterozygous for that trait. If the traits are inherited as dominant and recessive, the F₁ offspring will all exhibit the same phenotype as the parent homozygous for the dominant trait.
