What is multiple allele give example?
multiple alleles Three or more alternative forms of a gene (alleles) that can occupy the same locus. … For example, the ABO system of blood groups is controlled by three alleles, only two of which are present in an individual.
Which is an example of multiple alleles quizlet?
An excellent example of multiple allele inheritance is human blood type. Blood type exists as four possible phenotypes: A, B, AB, & O. Blood type exists as four possible phenotypes: A, B, AB, & O. You just studied 8 terms!
Is eye color an example of multiple alleles?
Yes, eye colour is an example of multiple alleles. They are more than two alleles encoding for the same.
What is an example of a alleles?
An example of an allele is the gene that determines hair color. … In almost all animal cells, two alleles for each gene are inherited, one from each parent. Paired alleles (one on each of two paired chromosomes) that are the same are called homozygous , and those that are different are called heterozygous .
Which of the following examples best define multiple alleles?
The best characterized example of multiple alleles in humans is the ABO blood groups, discussed in the Non-Mendelian Inheritance concept. Other human traits determined by multiple alleles would be hair color, hair texture, eye color, built, physical structures, etc.
What are multiple alleles in biology quizlet?

Multiple Alleles. – When three or more alleles control a trait. Example. Blood Types in humans.
Is skin color an example of multiple alleles?
Polygenic Inheritance: Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three “dominant” capital letter genes (A, B and C) control dark pigmentation because more melanin is produced.
How many alleles are there for eye color?
Two alleles make up the genotype. However, there may be other forms of alleles that are part of the gene and influence it. In fact, when it comes to eye color, the gene has several variations (alleles) such as one for blue eye color or a different allele for brown eyes.
Is hair color multiple alleles?
Brown hair color in humans is another example of a multi-allele trait, although human hair color is also a polygenic trait. … The alleles that code for darker shades have more activity than the lighter shades.
