Homozygous in a sentence

A homozygous dominant (AA) individual has a normal phenotype and no risk of abnormal offspring.

A homozygous recessive individual has an abnormal phenotype and is guaranteed to pass the abnormal gene onto offspring.

All offspring from the first generation will be heterozygous for the inserted gene and must be mated together to produce a homozygous animal.

Although the shorter life expectancy for those with the homozygous condition would tend to disfavor the trait's survival, the trait is preserved in malaria-prone regions because of the benefits provided by the heterozygous form.

An organism that has two identical alleles for a gene is said to be homozygous for that gene (and is called a homozygote).

If both alleles at a gene (or locus) on the homologous chromosomes are the same, they and the organism are homozygous with respect to that gene (or locus).

If both parents of a child have achondroplasia, and both parents pass on the mutant gene, then it is very unlikely that the homozygous child will live past a few months of its life.

In incomplete dominance, the heterozygous phenotype lies somewhere between the two homozygous phenotypes.

In these species, haploids are male and diploids heterozygous at the sex locus are female, but occasionally a diploid will be homozygous at the sex locus and develop as a male, instead.

In this ant, colonies with more homozygous queens age more rapidly.

Mares homozygous for the Lp gene bred to any color donkey will produce an Appaloosa colored mule.

Mendel used crosses between true-breeding (homozygous) pea plants for each of the seven traits.

Most (60%) are homozygous for ATP7B mutations (two abnormal copies), and 30% have only one abnormal copy.

Other advantages include the species' nearly constant size during early development, which enables simple staining techniques to be used, and the fact that its two-celled embryo can be fused into a single cell to create a homozygous embryo.

The disproportionate growth in numbers of white tigers points to inbreeding among homozygous recessive individuals.

They were all found to be homozygous for a mutation in the gene that caused Bovine Leukocyte Adhesion Deficiency.

This also differs from the 177 patients with vCJD, all of whom to date have been methionine homozygous (MM) genotype.

We say that the mutation is recessive because the organism will exhibit the wild type phenotype (ordinary trait) unless both chromosomes of a pair have the mutation ( homozygous mutation).

When parents are homozygous for each trait (SSbb and ssBB), their children in the F 1 generation are heterozygous at both loci and only show the dominant phenotypes (SsbB).
