What is meant by homozygosity and heterozygosity?

What is meant by homozygosity and heterozygosity?

Abstract. Homozygosity is the state of possessing two identical forms of a particular gene, one inherited from each parent. The opposite is heterozygous, the possession of two different forms of a particular gene, one inherited from each parent.

What is homozygous short answer?

(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 phenotype in biology?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

What is allele in biology?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.

What does homozygosity mean?

homozygosity – the state of being homozygous; having two identical alleles of the same gene. state – the way something is with respect to its main attributes; “the current state of knowledge”; “his state of health”; “in a weak financial state”.

What is the plural of homozygosity?

homozygosity (usually uncountable, plural homozygosities) The condition of being homozygous.

What is another name for homozygous?

Alternative forms of a given gene are called alleles, and they can be dominant or recessive. When an individual has two of the same allele, whether dominant or recessive, they are homozygous. Heterozygous means having one each of two different alleles.

What is homozygous science?

The definition of homozygous is when a cell has two identical copies of a gene. An example of homozygous is a cell containing blue eye genes from both parents.
