homozygote

The cell or organism in question is called a homozygote.

In the absence of the relaxant, the homozygote is at no known disadvantage.

It was assumed that the environment affected both identical (homozygote) twins in exactly the same way over an extended period of time.

Whrn homozygote mice show a moderate to severe hearing loss at 14 weeks.

Penetrance was almost complete for the recessive homozygote in all liability classes.

If the two alleles are identical, the individual is called a homozygote and is said to be homozygous.

Having two abnormal copies (homozygote) causes accelerated atherosclerosis in childhood, including its complications.

Also, there are some loci where the heterozygote is inherently fitter than either homozygote.

This usually happens when the heterozygote for a gene has a higher relative fitness) than the homozygote.

Female homozygote mutants had decreased circulating glucose levels.

This usually happens when the heterozygotes for the alleles under consideration have a higher adaptive value than the homozygote.

The effects of this allele are only seen when it is present in both chromosomes, gg (homozygote).

X-linked dominant inheritance will show the same phenotype as a heterozygote and homozygote.

This mutant is being kept at a high level in the population despite the lethal or near-lethal effects of the mutant homozygote.

This means that by age 30-59 a heterozygote or homozygote has a 26% risk of having ulcerative colitis.

The alternative homozygote, which does not carry the sickle cell disease allele, is susceptible to Plasmodium.

If they are heteroyygote with a dominant allele, the appearance (phenotype) is the same as a dominant homozygote.

As early as 1930 Fisher had discussed a situation where, with alleles at a single locus, the heterozygote is more viable than either homozygote.

This is because the homozygote for sickle cell has less chance of surviving to leave children, and if they do survive, they will have many health problems.

During meiosis in a translocation homozygote, chromosomes segregate normally according to Mendelian principles.

In practice heterozygote advantage puts a limit to the effect of selection, since neither homozygote can reach 100% of the population.

Heterozygote advantage is the situation where, at a gene locus, the heterozygote has greater fitness than either homozygote.

They do not get malaria so badly, and they do not suffer the earlier deaths of the homozygote sickle cell sufferers.

Twenty five tests were carried out on mutant mice and one significant abnormality was observed: male homozygote mutants were infertile.

Underdominance can also be described as homozygote advantage, wherein homozygous individuals have a higher fitness than heterozygous individuals.
