What causes varation in traits?
Genotypic variation is caused by mutation. Phenotypic variation can be caused by mutation, which gives rise to different alleles, or it can be caused by environmental factors.
What are some human traits that are caused by multiple alleles?
The heredity of the ABO blood groups are governed by multiple alleles.
What will a population with different alleles have?
A population with different alleles will have traits
What are traits inherited by multiple alleles?
Dominant Traits.
When a blend of both alleles are shown in the phenotype of an organism this is an example of?
A heterozygote expresses the traits of both alleles in the phenotypic traits. These traits affect the physical appearance of an organism.

How is the inheritance of traits controlled in organisms?
Individual alleles control the inheritance of traits. Some alleles are dominant, while others recessive.
What are traits of alleles are controlled by?
genes

How are multiple alleles different from polygenic traits?
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
Alleles passed from parent to child on a sex chromosome is called what?
These alleles are called sex-linked alleles or traits.
How are recessive and genes related?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.
