Best Answer

The human ABO blood group system is a good example of multiple alleles.

There are three alleles involved: IA, IB and IO.

If a person inherits two IA alleles, or IA and IO, they will be group A. If they inherit two IB alleles, or IB and IO, they will be group B.

If you inherit two IO alleles you will be group O.

What are some problems biologists face in studying human inheritance?

some problems biologist face is that studying human inheritance takes multiple generations to get a good grip on the dominant and recessive genes, because alleles can skip a generation. we have long, complex life cycles, and have few offspring. and it was difficult to track more than one gene at once.


What is selective breeding in terms of alleles?

Alleles are crossed from two different parents with the desirable trait. For example, if one female show horse produced a beautiful coat, and another male show horse also produced a beautiful coat, the breeder would breed the two horses to get the good-coat-producing gene in the offspring. The two alleles would produce the desired trait in the offspring.


How are the genotypes of parents related to the genotypes and phenotypes of the offspring?

alleles are variations of genes


What is the blood type of person who is heterozygous having A and B alleles codominant?

Blood types is a good example of codominance. There are three alleles for blood type, that can be represented as IA, IB, and i. IA and IB are both dominant to i, but when an individual inherits one of each the former two alleles (IAIB), he or she will have type AB blood. Instead of one allele being straightforwardly dominant to another, or the resulting phenotype being a halfway stage between the two alleles, the phenotype has aspects directly resulting from each allele.


Are male genes passed down?

Apparently yes they are.You can look at it in the chromosomal level.Genes from both male and female are passed down to the child.A good example is the sex chromosome.Male gives X or Y and the female gives only X.

How are alleles and genotypes related?

DNA is composed of long strings of nucleic acid sequences, but not all of them code for proteins. The ones that do are called genes. Alleles are different versions of a certain gene. For example, the gene that codes for blood type has 3 different alleles, A, B, and O. The genes that code for hair and eye color also have many different alleles.

What is systems tasks?

A Multi-tasking system is a system that can handle multiple tasks at the same time. Modern operating systems (Windows XP for example) can run multiple programs at the same time, and are a good example of multitasking systems


How do lions benefit from living in prides?

Since there is only one dominant make in the group (pride), the dominant male would reproduce and pass on its alleles to the next generation. As the alleles of the dominant male is good, the good quality alleles are passed on to the next generation which makes the gene pool stronger.
