Is it true that even though a gene has multiple alleles a person can carry only two of those alleles?

Is the following sentence true or false? Even though a gene has multiple alleles, a person can carry only two of those alleles. TRUE 5. Complete the table by writing all possible combinations of alleles for each blood type.

Can an individual ever possess more than two alleles for a particular gene?

Although individual humans (and all diploid organisms) can only have two alleles for a given gene, multiple alleles may exist in a population level, and different individuals in the population may have different pairs of these alleles.

How can multiple alleles provide many different phenotypes for a single trait?

Why can multiple alleles result in many different phenotypes for a trait? This can happen because the more allele options for a specific gene the more possible combinations and therefore possible phenotypes the organism that has that gene could inherit.

What is it called when a gene has more than two alleles?

Alleles are the pairs of genes occupying a specific spot called locus on a chromosome. Typically, there are only two alleles for a gene in a diploid organism. When there is a gene existing in more than two allelic forms, this condition is referred to as multiple allelism.

Why is a son who receives the allele for colorblindness from his mother always colorblind?

Colour blindness is a common hereditary (inherited) condition which means it is usually passed down from your parents. Red/green colour blindness is passed from mother to son on the 23rd chromosome, which is known as the sex chromosome because it also determines sex.

What does multiple allele mean?

Definition of multiple allele

: an allele of a genetic locus having more than two allelic forms within a population.

Why does an individual always have only two alleles for a given gene?

Since diploid organisms have two copies of each chromosome, they have two of each gene. Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other.

Why do multiple alleles and polygenic traits produce many different phenotypes for a trait?

3. Why do multiple alleles and polygenic traits produce many different phenotypes for a trait? Multiple alleles have more options for alleles, producing more phenotypes. Polygenic traits show a continuum of traits as they are controlled by multiple genes.

How many different phenotypes are possible?

There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.

How many different phenotypes are possible in the offspring quizlet?

With two alleles for a trait, up to three phenotypes are possible. With three alleles, up to six phenotypes are possible.
