Homozygous 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.
What is a gene pair that has two identical alleles?
Each pair of alleles represents the genotype of a specific gene. Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.
What is it called when someone has two alleles for the same trait?
If the paired alleles are the same, the organism’s genotype is said to be homozygous for that trait; if they are different, the organism’s genotype is heterozygous. …
Are two alleles in a gene pair always identical?
An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.
What are the two alleles for this trait?
What are the two alleles of this trait? The two alleles of this trait are the P and F1 traits.
When there are two identical alleles for a trait quizlet?
– An offspring with two identical alleles for a trait is homozygous. – An offspring with two different alleles for a trait is homozygous.
What is different between two alleles of the same gene quizlet?
What is different between two alleles of the same gene? The information they carry. For example, one allele might carry the information for blue eye pigment, while the other carries the information for brown eye pigment. Define Mendel’s law of independent assortment.
What is the difference between H * * * * * * * * * and heterozygous?
Humans have two sets of chromosomes. Homozygous and heterozygous are terms that are used to describe allele pairs.
Homozygous vs Heterozygous.
|Contains only one type of allele, either dominant or recessive||Contains different alleles for a trait. Both dominant and recessive|
Are pairs of genes that carry the same traits?
In humans, the 22 pairs of homologous autosomal chromosomes contain the same genes but code for different traits in their allelic forms, as one was inherited from the mother and one from the father.
How are a locus allele and a gene similar?
An allele is a variant of a gene. Each cell has two alleles (one per parent) for each gene: one dominant, one recessive. … Locus is to some extent interchangeable with gene, though locus is less specific and doesn’t imply that the location codes for an entire gene.
Which genotype consists of two identical genes for a given character?
Homozygous 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).
What is the genotype of a person trait if an organism has two identical alleles for that trait?
If an organism contains two identical alleles for a particular trait, the genotype for this trait is said to be homozygous.
What is a pair of genes called?
A pair of genes are called a pair of alleles and it is referred to as the genotype. If a person contains a pair of the same alleles, then it is called homozygous and if the two alleles are different it is termed as heterozygous.
