Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Chromosome pairs can contain only one allele, or version of a gene.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -An allele is found at a fixed spot on a chromosome. Chromosomes occur in pairs so organisms have two alleles for each gene-one allele in each chromosome in the pair. Since each chromosome in the pair comes from a different parent, organisms inherit one allele from each parent for each gene.

Detailed explanation-3: -"Alleleā€ is the word that we use to describe the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to lump the alleles into categories.

Detailed explanation-4: -Well, alleles are matching genes; one from our biological mother, one from our biological father. We have two copies of every gene (strings of code that drive some biological function on our chromosomes). They can be identical, but they can often have slight differences.
