Why multiple alleles can be found only when population studies are made?
Here there are more than two alleles (Ia, Ib , i) governing the same character. Since in an individual only two alleles can be present , multiple alleles can be found only when population studies are made.
Can multiple alleles only be studied in individuals?
Traits controlled by more than two alleles are said to have multiple alleles. Multiple alleles can be studied only in individuals. In humans, there are 23 pairs of matching homologous chromosome called autosomes. Two chromosomes called the sex chromosomes determine the sex of an individual.
What is the significance of multiple alleles within a population?
Although humans (and all diploid organisms) can have only two alleles for any given gene in genetics, multiple allele traits may exist at the population level. Thus, multiple alleles are important in promoting variation within the same species.
How is it possible that there are multiple different alleles in a population and yet any individual can have only two alleles?
Multiple alleles exist in a population when there are many variations of a gene present. In organisms with two copies of every gene, also known as diploid organisms, each organism has the ability to express two alleles at the same time. They can be the same allele, which is called a homozygous genotype.
Which of the following can be found only when population studies are made?
Answer. A diploid organism has only two alleles of a character, although it has more than two alleles. Multiple alleles can be found only when population studies are made.
Which among the following can be found only in population studies?
Video Solution: Multiple alleles can be found only when population studies are made. Multiple alleles can be found only when population studies are made.
Can a gene have multiple alleles?
When the copies of a gene differ from each other, they are known as alleles. A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual.
What is multiple alleles explain with the help of an example?
Multiple alleles refer to the occurrence of three or more than three alleles for a particular gene. Alleles are different or contrasting forms of a gene. For example, for the gene encoding for height, one allele can be for tallness, whereas the other can be for dwarfness.
Are multiple alleles rare?
Yet the exponential growth of the human population has resulted in many new alleles, each individually rare and each specific to one population (or even one family). Most alleles are of this sort. Thus the paradox: most human variation is ancient and shared; most alleles are recent and individually rare.
