Weballele. An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid ... WebAug 21, 2024 · Multiple Alleles . While most genes exist in two allele forms, some have multiple alleles for a trait. A common example of this in humans is ABO blood type.

Gene Definition, Structure, Expression, & Facts
WebOften, there are multiple versions of the same gene called alleles. Although each allele codes for the same type of trait, they will each express a different version of the trait. For example, roses have a color trait with genes that specify what color the rose will be (type of trait). However, there are many different colors of roses (versions ... 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 hair color gene, … See more Genes are very specific segments of DNA(deoxyribonucleic acid). Each of your cells contains very long stretches of DNA. This is heritable … See more The genetic code of human beings is quite similar: Well over 99 percent of nucleotides that are part of genes are the same across all humans. Alleles, however, have variations in the sequence of nucleotides in … See more You can sometimes get genetic diseases if you have heterozygous genes. In some types of genetic diseases, heterozygous genes almost always cause the disease. In diseases caused by dominant genes, a person needs only … See more Many gene variations aren’t a big deal and just contribute to normal human variation.
