If there are 6 multiple alleles of a gene, them how many types of homozygous conditions possible in the population?

Question

Answer

Number of Homozygous Conditions with 6 Multiple Alleles of a Gene

When there are multiple alleles of a gene, each individual can have two copies of the same allele (homozygous) or two different alleles (heterozygous). The number of homozygous conditions possible in the population depends on the number of different alleles present. In the case of 6 multiple alleles, the number of homozygous conditions is:

Homozygous Dominant: This occurs when an individual has two copies of the dominant allele. In this case, there is only one dominant allele, so there is only one homozygous dominant condition possible.

Homozygous Recessive: This occurs when an individual has two copies of the recessive allele. In this case, there are five recessive alleles, so there are five homozygous recessive conditions possible.

Null Homozygous: This occurs when an individual has two copies of a non-functional allele. In this case, there is only one null allele, so there is only one null homozygous condition possible.

Therefore, the total number of homozygous conditions possible in the population with 6 multiple alleles of a gene is 7.

Answer

The possibility of homozygous condition is two, one homozygous dominant and another homozygous recessive. All other genotypes will be intermediate of these two.
