What is it called when there are more than two alleles present in a population?
Chromosomes are made of tightly wound DNA and protein. Genes are found along the length of chromosomes. A gene is a segment of DNA that contains instructions for making a specific protein or proteins required by the body. Human beings have about 30,000 - 35,000 genes. We have two copies of each gene, but the copies can be slightly different. For example, the gene associated with cystic fibrosis has more than 1000 different variations. Different versions of the same gene are called its alleles, and everyone has two alleles for each gene. (Males have only one X chromosome, so they only have one copy of the genes located on the X chromosome.)
What is the alternate form of a gene called?
Alleles are alternative forms of genes.
What are genes with three or more alleles called?
this makes no scientific sense. A gene (which determines a phenotypic trait) can only contain 2 alleles. However codominace allows for multiple alleles to be chosen from, but only 2 picked for a gene. Also, if multiple genes determine a phenotypic trait that's polygenic inheritance.
What is the relationship between genes and alleles?
The gene loci are the sites where the alleles reside on the DNA strand. Alleles at the same gene locus on each chromosome pair will determine the phenotypic expression of that gene pair. Of course this explanation is incomplete when more complex interactions between alleles come into play
Two or more pairs of alleles segregate independently?
It's segregation! :P
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
When a gene has more than two alleles the condition is known as?
multiple alleles

What is multiple aleles?
Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
Why do you have more genotypes than phenotypes?
Because those alleles segregate, or seperate, and combine again to make different alleles, thus making different phenotypes.

What is multiple allele gene expression?
Instead of having only two alleles for a trait, there are more than two. An example in humans is the ABO blood group system, where there are three alleles that are possible. However, an individual can only inherit the alleles of his/her parents, for a total of two alleles.

The blood type trait which is controlled by more than two alleles for a given gene and therefore is called?
multiple alleles

What are multiple allels in biology?
Multiple alleles is a type of heredity in which one gene has more than two alleles. For example, in humans the gene for blood group has three alleles, A, B, and O. Even though there are three alleles in the population, a person can only inherit two alleles, one from his/her mother and one from his/her father.
