How many alleles are there for homozygous?
How many alleles are there for homozygous?
two alleles
Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.
How many alleles are heterozygous?
two different alleles
In a heterozygous genotype, the two different alleles interact with each other. This determines how their traits are expressed.
How many alleles do you have for 1 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.

How many alleles do we have?
While there are three alleles, each of us has just two of them, so the possible combinations and the resulting blood types are those shown in the table below.
When there are 3 or more alleles of a gene existing in a population that can occur at one location on a chromosome this is called?
Those instances are referred to as “multiple allelism” where different forms of the same gene exist within the population. These three or more variants for the same gene are called multiple alleles.
How do you explain alleles to a child?
Allele – While the section of DNA is called a gene, a specific pattern in a gene is called an allele. For example, the gene would determine the hair color. The specific pattern of the hair color gene that causes the hair to be black would be the allele. Each child inherits two genes for each trait from their parents.
How do you explain allele to a child?
An allele is a form of a gene at a particular position (locus) on a chromosome. It is the bit of coding DNA at that place. Typical plants and animals have two sets of chromosomes, one set inherited from each parent. These organisms are called diploid.
