What is a gene that has 4 alleles?
One example of a gene with four alleles is the ABO blood group gene, which determines human blood types. The gene has three main alleles: A, B, and O, with the A and B alleles being co-dominant and the O allele being recessive. However, the presence of additional alleles, such as those associated with rare subtypes (like Ax or Ay), can extend the total number of recognized alleles for this gene. This genetic variability contributes to the diversity of blood types in the population.
What is the minimum number of alleles that may be present for a given genotype controlled by a single gene?
The minimum number of alleles that may be present for a given genotype controlled by a single gene is one. This occurs in the case of a homozygous genotype, where an individual carries two identical alleles for that gene. However, if considering a heterozygous genotype, two different alleles would be present. Thus, for a single gene, the minimum is one, while the maximum can be two in diploid organisms.
Two different forms of the same gene are called?
Alleles
Which term describes the movement of alleles into out of a population?
Gene flow
How many allels per gene are there in each stage of meiosis?
there are the same number of alleles per gene in each stage of meiosis since the number of alleles per gene only tells the possible differences in a gene, such as the alleles for blue, green, and brown eyes being the possible traits to be combined.
Different versions of the same gene are called?

Different or alternative forms of the same gene are called?
Alleles are alternate forms of the same gene. A gene is the basic physical unit of heredity that is passed on from a parent to their children.
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.
Different forms of a gene?
the alternative form of a gene is called an "allele."

What are two forms of a gene called?
The two different molecular forms of a gene are called alleles.
Difference between a gene and an allele?
The alleles are the different forms of the gene. This is simplified, but an example might be, if the gene is "eye color," the alleles would be "green, blue, brown, etc." The variations in the gene are the alleles.
What are the alleles of a gene?
That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
How many allels per gene are there in each stage of meiosis?
there are the same number of alleles per gene in each stage of meiosis since the number of alleles per gene only tells the possible differences in a gene, such as the alleles for blue, green, and brown eyes being the possible traits to be combined.
