You asked: What do the terms homozygous and heterozygous mean quizlet?

What does homozygous and heterozygous 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 does homozygous and heterozygous mean?

Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.

What does it mean to be homozygous quizlet?

homozygous. an organism that has two identical alleles for a trait (purebread) phenotype.

What does homozygous dominant mean quizlet?

Homozygous dominant refers to the alleles both being uppercase traits. Ex. RR. Heterozygous. Heterozygous means that the alleles are two different traits.

What is the term heterozygous mean?

(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

What is homozygous example?

If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous.

How are homozygous and heterozygous similar?

An organism that is homozygous has two copies of the same allele. An allele is one version, like a “flavor”, of a gene. … Homozygous means having two of the same allele. Heterozygous means having two different alleles.

What is the difference between heterozygous and heterozygote?

Heterozygous. A diploid organism is heterozygous at a gene locus when its cells contain two different alleles (one wild-type allele and one mutant allele) of a gene. The cell or organism is called a heterozygote specifically for the allele in question, and therefore, heterozygosity refers to a specific genotype.

What are heterozygous alleles represented by?

Heterozygous is a genetic condition where an individual inherits different alleles of a gene from the two parents. Genotype representation. Homozygous genotypes are represented as AA or aa for homozygous-dominant or homozygous-recessive conditions, respectively. Heterozygous genotypes are represented by Aa genotypes.

Which is an example of a heterozygous allele quizlet?

Heterozygous alleles are alleles that act on different colors. For example allele for blue & allele for black.

What is the definition of homozygous dominant?

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.

Which is a heterozygous genotype quizlet?

Also known as heterozygous (Bb). An organism that has two different alleles for a given trait.

What is the homozygous dominant genotype what phenotype results quizlet?

A homozygous dominant individual (AA) is crossed with an individual that is heterozygous for the same trait (Aa). What are the possible genotypes of the offspring and what percentage of the offspring is likely to show the dominant phenotype? AA and Aa will result; 100% will have the dominant phenotype.

What does homozygous recessive mean?

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.
