Best answer: What is heterozygous trait?

Which is an example of a heterozygous trait?

Your genes are made of DNA. … If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.

What are heterozygous and homozygous traits?

An organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for a particular trait is considered heterozygous for that trait.

What are two traits heterozygous?

A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. … Therefore, a dihybrid organism is one that is heterozygous at two different genetic loci.

Which is heterozygous AA AA or AA?

Homozygous means that both copies of a gene or locus match while heterozygous means that the copies do not match. Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

What is the difference between H * * * * * * * * * and heterozygous?

While individual organisms bearing different alleles (Rr) are known as heterozygous.

Homozygous vs Heterozygous.

Homozygous Heterozygous
Contains only one type of allele, either dominant or recessive Contains different alleles for a trait. Both dominant and recessive

Is heterozygous recessive or dominant?

An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive.

What is the difference between a homozygote and heterozygote?

A heterozygote is an individual having two different alleles at a genetic locus; a homozygote is an individual having two copies of the same allele at a locus.

What happens when both parents are heterozygous?

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). A Punnett square can be used to determine all possible genotypic combinations in the parents.
