If any of their children exhibit a different trait, then that indicates they were carriers of a recessive trait and so they must be showing a dominant trait. What are dominant alleles and recessive alleles? A dominant allele will lead to expression of the dominant trait in both homozygous ...
Other times, the alleles may be codominant, resulting in a different phenotype for the heterozygote (curly fur) than for either of the homozygotes (normal or hairless). If an allele is lethal to homozygotes, it can still be passed on by heterozygous carriers. Read Heterozygous | Definition,...
It is a heterozygous genotype for a particular gene if there are two different versions of it. For instance, a heterozygous for eye colour corresponds to say that you have one allele for black and one for brown.
Fundamental questions in human biology and therapeutic development have been evaluated using transgenic model organisms, typically generated by pronuclear injection. Despite its widespread use, relatively little is known concerning the detailed impact of random transgene integration on the host genome as a...
The traditional North American sweet maize is homozygous for a recessive sugaryl (sul) allele. Determining the number of unique alleles among sul maize races is relevant to the debate in archeology and evolutionary biology over whether independent mutation or migration plays a dominant role in the ...
Dihybrid cross-pollination experiments led Gregor Mendel to develop his law ofindependent assortment. This law states that alleles are transmitted to offspring independently of one another. Alleles separate during meiosis, leaving each gamete with one allele for a single trait. These alleles are random...

A novel rearranged band, in addition to the germ line band derived from the normal allele, indicates the presence of rearrangement. Probes in the vicinity of the suspected breakpoints are always used. The detection of rearrangements depends on clustering of the breakpoints in one of therearrang...
The trait of eye color is coded for several genes. Each of these genes have different alleles that can be inherited, such as an allele for blue eyes or an allele for brown eyes. The specific combination of alleles someone inherits determines their trait which, in this case, is eye color....
