A number of genetic disorders are caused when an individual inherits two recessive alleles for a single-gene trait. Recessive genetic disorders include albinism, cystic fibrosis, galactosemia, phenylketonuria (PKU), and Tay–Sachs disease. Other disorders are also due to recessive alleles, but because the gene locus is located on the X chromosome, so that males have only one copy (that is, they are hemizygous), they are more frequent in males than in females. Examples inclu… WebJun 16, 2024 · The human ABO blood type alleles/trait is einer example of a trait with multiple allele-specific.

In a dominant/recessive relationship between two alleles, the recessive allele’s effects are masked by the more dramatic effects of the dominant allele. An allele is a specific variation of a gene, or specific segment of DNA. WebFor example: Imagine a population of 4 organisms which have one gene for color with two alleles - lets say a dominant allele called A and a recessive allele called a. The individuals have the following genotypes: #1=AA #2=Aa #4=aa A storm happens and by chance a tree falls on individual 1 and kills it – so sad! schalke harit news
