Homozygous is a genetic condition where an individual inherits the same alleles for a particular gene from both parents.
What does homozygous refer to?
(HOH-moh-ZY-gus JEE-noh-tipe) The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.
What is the best definition for homozygous?
Definition of homozygous
: having the two genes at corresponding loci on homologous chromosomes identical for one or more loci.
What is another term for homozygous?
If the two alleles at a locus are identical to each other, they are homozygous; if they are different from one another, they are heterozygous. Like all words with the prefix hetero, heterozygous has to do with things that are different — specifically genes. When alleles are heterozygous they are unalike in some way.
What does homozygous mean in a sentence?
genetics. (of an organism) having identical alleles for any one gene. these two fruit flies are homozygous for red eye colour.
What is 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 do you call homozygous and heterozygous?
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. In plant and animal breeding, such organisms can be called homozygotes and heterozygotes.
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.
What is a heterozygous trait?
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’s another term for heterozygous?
In this page you can discover 11 synonyms, antonyms, idiomatic expressions, and related words for heterozygous, like: homozygous, genotype, allele, recessive, MTHFR, C282Y, rb1, heterozygote, premutation, wild-type and homozygote.
What is the prefix of homozygous?
Homozygous is a Greek-derived word – the prefix homo means same; zygous comes from zugos – a word that implies being joined together. The terms heterozygous and hemizygous tell that two alleles composed of the sequences from two parents are different (hetero) or half (hemi) respectively.
What does homozygous mean in horses?
If a horse carries two copies of the same allele for a gene, he is homozygous (for instance, E/E or e/e, with the lowercase letters indicating recessive genes, and capital letters signifying dominant) for that trait. If he carries one dominant and one recessive allele, then he is heterozygous (E/e) for the trait.
What do we refer to as an organisms genotype?
In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes.
