How alleles and genes related?
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.
What is an organism with two genes for a trait called?
An organism with two like alleles for a trait is homozygous for that trait.
What organisms with two alleles are called?
Genes
The two or more related genes that control a trait are known as?
alleles
What does a genes have two or more of?
Genes can have two or more alleles, which are different versions of a gene that can exist at a specific locus on a chromosome. These alleles can contribute to variations in traits among individuals. In diploid organisms, such as humans, genes typically have two alleles, one inherited from each parent. The combination of these alleles can determine the expression of specific traits.
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.
When the alleles present for a trait are the same. the genes are called?
When the alleles present for a trait are the same, the genes are called homozygous. This means that both alleles for a particular gene are identical. Homozygous individuals can have either two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive).
What has same alleles?
Two or more genes which control the same characteristic.
What are the two types of alleles traits?
The two types of alleles for traits are dominant alleles and recessive alleles. Dominant alleles are expressed when at least one copy is present, while recessive alleles are only expressed when two copies are present.
What are contrasting forms of genes called?
Alleles
What are genes that have more than two alleles?
ABO blood groups in humans,Coat color in rabbits is determined by four alleles,human-leukocyte-associatedantigen(HLA) genes
Two ways multiple alleles and polygenic traits differ?
Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
