What are the two types of alleles?

Alleles are described as either dominant or recessive depending on their associated traits.

Is a genotype 2 alleles?

Each pair of alleles represents the genotype of a specific gene. For example, in sweet pea plants, the gene for flower color has two alleles. A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ.

What individual has two alleles?

heterozygous
An individual that contains two different alleles of a gene is heterozygous.

What are the three types of alleles?

There are three different alleles, known as IA, IB, and i. The IA and IB alleles are co-dominant, and the i allele is recessive. The possible human phenotypes for blood group are type A, type B, type AB, and type O.

What are alleles example?

Alleles are different forms of the same gene. An example of alleles for flower color in pea plants are the dominant purple allele, and the recessive white allele; for height they are the dominant tall allele and recessive short allele; for pea color, they are the dominant yellow allele and recessive green allele.

What are identical alleles?

Copies of genes are referred to as “alleles,” and because of the way reproduction works, the alleles can carry identical copies of a gene or different copies, depending on what is passed on by each parent. Identical alleles means that a person’s genotype for that trait is homozygous.

How many types of alleles are there?

two alleles
Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene.

What are examples of alleles?

Examples	Eye color, hair color, skin pigmentation	Blue eyes, brown hair, dark skin

What is different between two alleles of the same gene?

If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.
