Quick Answer: What does it mean when an organism is heterozygous for a trait?

What does it mean to be homozygous or heterozygous for a trait?

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. They do not match.

What does it mean if a person is homozygous for a trait?

Homozygous is a genetic condition where an individual inherits the same alleles for a particular gene from both parents.

What is an organism that is heterozygous for a specific trait is called?

hybrid. an organism that has different alleles for a trait: an organism that is heterozygous for a particular trait.

What does it mean if you are heterozygous for a trait quizlet?

heterozygous. an organism that has two different alleles for a trait (hybrid)

What is the difference in heterozygous and homozygous?

We all have two alleles, or versions, of each gene. Being homozygous for a particular gene means you inherited two identical versions. It’s the opposite of a heterozygous genotype, where the alleles are different. People who have recessive traits, like blue eyes or red hair, are always homozygous for that gene.

What is heterozygous trait?

By. Getty Images. Heterozygous is a term used in genetics to describe when two variations of a gene (known as alleles) are paired at the same location (locus) on a chromosome. By contrast, homozygous is when there are two copies of the same allele at the same locus.

Are humans homozygous or heterozygous?

Homozygous and Heterozygous

Since humans possess two copies of each chromosome, they also have two copies of each gene and locus on those chromosomes. … If the alleles match, the person is homozygous for that trait.

What does homozygous mean quizlet?

Homozygous means that. An offspring either has 2 copies of the dominant allele or 2 copies of the recessive allele. Heterozygous means that. The offspring has 1 copy of the dominant allele and 1 copy of the recessive allele.

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.
