When a person inherits two of the same alleles for a trait they are said to be homozygous for the trait (with homo meaning the same). When a gene is recessive (like the one for red hair) a person has to be homozygous for the trait for it to be expressed. If both parents had ...
Homozygous Definition Diploid organisms that have a genotype of identical alleles for a trait or phenotype at a specific locus are described as homozygous. Such organisms could be either homozygous dominant or homozygous recessive. In such organisms, two traits can be expressed — either dominant or...
In-Depth Homozygous Definition Homozygous alleles may be dominant or recessive. Ahomozygous dominantallele combination contains two dominant alleles and expresses the dominant phenotype (expressed physical trait). Ahomozygous recessiveallele combination contains two recessive alleles and expresses the recessive ...

If a dominant gene causes a disease, a person with a heterozygous pair of alleles may manifest the disease. If a recessive gene causes a disease, a person with a heterozygous pair of alleles may not develop the disease or may have lesser effects. ...
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. Read Homozygous vs. Heterozygous | Definition & Differences Lesson ...
or dominant. Dominant alleles are expressed to give rise to a phenotype, whereas the recessive alleles remain unexpressed. Both the recessive and dominant alleles are found on the same locus of the homologous chromosomes. The heterozygous entities carry both the recessive and dominant alleles. ...

(SNVs), recessive/homozygous SNVs, or de novo copy number variants (CNVs); however, most ASD cases continue to lack a genetic diagnosis. We analyzed 187 consanguineous ASD families for biallelic CNVs. Recessive deletions were significantly enriched in affected individuals relative to their ...
