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.
alleles are variations of genes
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.
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.
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.
The diversity seen in Darwin's finches is a good example of adaptive radiation, where a single ancestral species diversifies to fill multiple ecological niches. This phenomenon highlights the role of natural selection in driving evolutionary change and the importance of environmental pressures in shaping the evolution of species.
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.
no because genes are something totally different
Because Tacos are good
no because genes are something totally different
They had good genes (No, not jeans. Genes as in DNA.)
No
I guess the best way to answer that is genetic variation.... otherwise we would all have the same physical characteristics. This ensures health of a species as some people may be more resistant to a virus than another and so theoretically the fitter and stronger will produce more young and pass on those 'good' genes to more offspring. Added: Mutation can produce different molecular forms of the same gene. This is the ultimate reason for alleles. Just remember that mutations are rare..especially beneficial ones or neutral ones that have no effect on the individual.
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

no 'cause genes are your bodies make up and jeans are a long pant clothing articles.
Yes, because the environment shapes people. For example, if two genetically identical children are raised in two different environments, one with good nutrition and one without, the one with good nutrition will probably be much taller and healthier than the one without, even though they have the same genes.
