- Definition: Homozygous refers to having identical alleles for a single trait. Related Terms: Allele, Genes, Heterozygous. Examples: The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r).

Heterozygote advantageupdate A common example is the case where the heterozygote conveys both advantages and disadvantages, while both homozygotes convey a disadvantage. A well-established case of heterozygote advantage is that of the gene involved in sickle cell anaemia.

2 Examples of Heterozygous Traits Any time an individual has two different alleles for a gene, the individual's genotype is heterozygous. For genes with simple dominance, like the pea example, the dominant allele is always expressed, so heterozgyous individuals have the dominant trait.ny time an individual has two different alleles for a gene, the individual's genotype is heterozygous.

heterozygous having two different alleles at corresponding loci on homologous chromosomes. An individual who is heterozygous for a trait has inherited an allele for that trait from one parent and an alternative allele from the other parent. An individual who is heterozygous for a genetic disease caused by a dominant allele, such as Huntington's disease, manifests the disorder. A person who is heterozygous for a hereditary disorder produced by a recessive allele, such as sickle cell anemia, is asymptomatic or exhibits reduced symptoms of the disease.

- 1 Heterozygous means it has two different alleles (Ff).  2 Homozygous dominant means it has two copies of the dominant allele (FF).  3 Homozygous recessive means it has two copies of the recessive allele (ff). 4  Any parent that shows the recessive trait (has yellow fur) belongs to this category.

Mendel's First Law of Genetics (Law of Segregation) Homozygote - an individual which contains only one allele at the allelic pair; for example DD is homozygous dominant and dd is homozygous recessive; pure lines are homozygous for the gene of interest. Heterozygote - an individual which contains one of each member of the gene pair; for example the Dd heterozygote.

Heterozygous Traits An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome.These DNA codings determine distinct traits that can be passed on from parents to offspring.ince organisms have two alleles for each trait, when the alleles of a pair are heterozygous, the dominant allele trait is expressed and the recessive allele trait is masked. Seeds with the genetic makeup of (YY) or (Yy) are yellow, while seeds that are (yy) are green.

Alleles, Genotype and Phenotype Individuals who have two copies of the same allele are said to be homozygous at that locus. Individuals who receive different alleles from each parent are said to be heterozygous at that locus. The alleles an individual has at a locus is called a genotype.The genotype of an organism is often expressed using letters.ndividuals who receive different alleles from each parent are said to be heterozygous at that locus.

- homozygous means you have two alleles with the same characteristic. example; two alleles for brown eyes. recessive means that when you have two different alleles, one of then doesn't show its trait. example; one allele for brown eyes and one allele for green eyes gives brown eyes, because green eyes are recessive. people who have green eyes have homozygous recessive alleles for green eyes (two alleles for green eyes).

What does homozygous, heterozygous, genotype, phenotype mean? Reply. Homozygous – having identical alleles for a single trait. Heterozygous – having two different alleles for a single trait. genotype – genetic structure of a cell or organism. Phenotype – physical or biochemical characteristics of an organism. Reply. Homozygous-two alleles for a specific gene that are the same.

What is the difference between homozygous and heterozygous? Humans contain two copies of each gene, one from the father and one from the mother, which sometimes are referred to as the alleles of a gene. If a mutation occurs in just one copy of the gene then that individual is considered heterozygous.n heterozygous genotypes one copy of the gene is healthy and can produce fine proteins thus these individuals are usually not affected and are considered just carriers. However in a few hereditary disorders heterozygous individuals may suffer from a milder version of the disease.

"What does ""homozygous"" mean?" Alleles are alternative forms of a gene. They can be dominant or recessive. When fertilization occurs, a zygote is formed with genetic information from both parents. When the same allele for a particular gene is received from both parents, the condition is known as homozygous (equal in the zygote).

Allele: A Genetics Definition When the alleles of a pair are heterozygous, one may be dominant and the other recessive. The dominant allele is expressed and the recessive allele is masked. This is an example of complete dominance.In heterozygous relationships where neither allele is dominant but both are completely expressed, the alleles are considered to be co-dominant. Co-dominance is exemplified in AB blood type inheritance.hen the alleles of a pair are heterozygous, one may be dominant and the other recessive. The dominant allele is expressed and the recessive allele is masked. This is an example of complete dominance.

- Remember, individuals must have two alleles for a gene, so someone could be homozygous dominant (EE), homozygous recessive (ee), or heterozygous (Ee). In this example, the recessive trait is having attached earlobes and is only seen in someone with the genotype ee (homozygous recessive).xamples of Recessive Traits. We know many examples of traits controlled by recessive alleles; however, as scientists are more thoroughly studying the genetics of traits, they are finding that many have multiple genes and alleles associated with them, instead of just one gene with two alleles as explained above.

- A - The alleles for a trait occupy the same locus or position on homologous chromosomes and thus govern the same trait. However, because they are different, their action may result in different expressions of that trait.omozygous also refers to a genotype consisting of two identical alleles of a gene for a particular trait. An individual may be homozygous dominant (AA) or homozygous recessive (aa). Individuals who are homozygous for a trait are referred to as homozygotes. See heterozygous.

- There are two forms of Homozygous inheritance: Homozygous Dominant, and Homozygous Recessive. In order for two parents that are Homozygous to produce a Heterozygous offspring, … one of them MUST be Homozygous Dominant, and the other MUST be Homozygous Recessive.t depends. If it's a heterozygous cross, (Tt x Tt), there's a 25% chance. If it's a homozygous dominant cross (TT x TT), the chance is 0%. Neither parent has the alleles for … a recessive trait, so none of their offspring can have the recessive trait.
