The designations of heterozygous and homozygous don't refer to individual people but to individual genes. For example, you can be heterozygous for the gene that controls hair color, but homozygous for the gene that controls eye color. This just means that you have two different versions of the...
Beinghomozygous fora trait means that it will always turn out the same. But beingheterozygousmeans that the trait can develop in different ways. Remember, an organism isn’t said to behomozygousorheterozygousoverall—just for a single trait. Examples ofhomozygousandheterozygousused in a sentence Her...
Dominant traits like whether you can roll your tongue or have a genetic predisposition to developing Huntington's disease only require one dominant allele to express. This means that people with homozygous dominant alleles (AA) and heterozygous alleles (Aa) express those traits, but people with hom...
This type of genotype may depict a higher fitness relative to either the homozygous recessive genotype or homozygous dominant genotype. This is referred to as a heterozygote advantage. Some examples of genotypes are – height, hair colour etc. Heterozygous phenotype The phenotype, in simple terms, ...

Heterozygous vs. Homozygous An individual that ishomozygousfor a trait has alleles that are similar. Unlike heterozygous individuals with different alleles, homozygotes produce only homozygous offspring. These offspring may be either homozygous dominant(RR)or homozygous recessive(rr)for a trait. They may...
Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene
We investigated the molecular basis of disease in two brothers with OFD type II, Mohr syndrome, by performing single-nucleotide polymorphism (SNP)-array analysis on the brothers and their healthy parents to identify homozygous regions and candidate genes. Subsequently, we performed whole-exome ...
parent strain while isolate yYW167 grew well at all temperatures tested. At high temperatures, one round of SCRaMbLE was sufficient to recover growth of yYW167 to the level of the Y12 homozygous diploid. Fig. 2 SCRaMbLE of Y12-synX rapidly improves thermotolerance.aSerial dilution assay comparin...
In this study, we found a higher firing activity in neurons from old heterozygous 3xTg-AD of both sexes, which was similar to what we previously observed in homozygous 3xTg-AD mice [35]. In agreement with the higher firing activity found in 3xTg-AD neurons, our results also revealed an...
