You asked: How many types of alleles are there what are these Brainly?

Answer: Alleles refer to the alternative form of the same gene. These are mainly of two types: dominant and recessive allele.

How many types of alleles are there what are these?

An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.

What is an allele What are the two types of alleles?

How many alleles are there for four main types of human blood Brainly?

Explanation: There are three alleles for human blood type: A, B, and O. These three alleles create the four main types of human blood: A, B, AB, and O.

What is an allele Brainly a form of a gene?

Explanation: An allele is one of the different variants of a gene. It is one of the two or more genes found on the same locus on a chromosome which determines a specific trait in an organism. An allele can be dominant or recessive.

What is the best definition of allele?

Allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait.

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.

How many genotypes are possible for the offspring?

Genotype is also used to refer to the pair of alleles present at a single locus. With alleles ‘A’ and ‘a’ there are three possible genotypes AA, Aa and aa. With three alleles 1, 2, 3 there are six possible genotypes: 11, 12, 13, 22, 23, 33.

How many alleles are there for the main blood types found in the human population two alleles three alleles four alleles Brainly?

Blood type exists as four possible phenotypes: A, B, AB, & O. There are 3 alleles for the gene that determines blood type.

Which best describes the factors that affect a phenotype?

The genotype and the environment both affect phenotype. Explanation: Phenotype is the outward expression or make up of an organism. The phenotype is simple the physical outlook of an organism.

What is an allele apex answers?

One of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. … An allele is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus (position) on a chromosome.

What is chromosome 10 Brainly?

A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
