Huntington's Disease is a single gene disease. It is an autosomal dominant disorder that causes nerve cells to degenerate over time. What is possible gene pairs? Possible gene pairs refers to the potential combinations of alleles, leading to different expressions of traits. In single gene inherita...
This lesson will discuss the concept of gene regulation, how genes are regulated, as well as some mechanisms that enable it. It will also cover the...
The variants of a gene controlling the same trait and occupying a specific region on a chromosome are referred to asalleles. A particular trait may be determined by a pair of alleles or by the interaction of a series of alleles as in the case of themultiple allelic traits(or polygenic inhe...
Adenosine deaminase deficiency is one of few "curable" genetic diseases. It is caused by a mutation in a single gene essential to normal development of the immune system. Bone marrow transplants have been found to be of some value to patients. In addition, gene therapy has been successful at...
Each of them produces an effect that adds up to the trait. Nevertheless, the effect of an individual gene is hard to distinguish, especially since a polygenic character involves several genes.In humans, height, skin color, hair color, and eye color are examples of polygenic traits....

A gene tree is a phylogenetic tree constructed using data for a single gene. This term opposes the concept of the species tree [39] (p. 189), [45,51] (p. 240), which includes a phylogenetic signal for several genes and may incorporate other traits. A phylogenetic tree, including a ...
Genesare segments ofDNAthat encode specific proteins, influencing traits like eye color. Different versions of genes, known asalleles, can be represented by capital and lowercase letters (e.g., B for blue eyes, b for brown eyes).Cellploidy refers to the number of chromosome sets in a cell...
