Genes determine our eye colour. Eye genes usually come in two alleles: an allele for brown eyes and an allele for blue eyes. We all have a pair of alleles that determine our eye colour. An individual who carries two copies of the same allele is homozygous. An individual who carries two ...

One allele may be dominant while the other is recessive, eye color often being cited, with the brown allele being dominant over the blue allele. This phenomenon has been modeled by the Punnett square for almost a century, before any real knowledge of DNA. As the square suggests, two parents...
What is a multiple allele trait? What are single-allele traits? What is inheritance in biology? What are recessive traits? What is the function of genes in biology? What type of traits are considered polygenic traits? What is Mendelian genetics?
allele, appeared in a study population of both transsexual women (male-to-female) and non-transsexual men, and found that there might be a link between certain alleles ofARand being transsexual. Male-to-female transsexuals were more likely to have a particular number of tandem repeats in the...
What is an Amorph genetics? An amorph isa mutated allele that has lost the ability of the parent allele(whether wild type or any other type) to encode any functional protein. An amorph mutation is the loss of genetic information for the synthesis of appropriate mRNA. ...
A recessive allele will only lead to expression of a recessive trait in homozygous recessive individuals.What is a Recessive Trait? A recessive trait definition is one that is only expressed when an organism has two recessive alleles for that trait. A trait is an observable characteristic. This...
A person who has a mutated allele but does not express the disease phenotype is called a carrier. Another example where a carrier has protein level incomplete dominance occurs in the disease sickle-cell anemia. Incomplete Dominance vs Codominance Recognizing Incomplete Dominance Lesson Summary Register...
Gene Therapyin Monogenic Disease Monogenic genetic disease refers to a genetic disease controlled by one allele. There are more than 6600 kinds of monogenic diseases identified so far – this figure is increasing at an alarming rate of 10-50 every year and poses a great threat to human health...
Define what multiple alleles are in the study of genetics. What is the difference between a genotype and an allele? What are the 4 phenotypes of blood? What are the 3 alleles? What are the 6 possible genotype options of blood? Genotype is to what, as phenotype is to what?
