Genes responsible for hereditary variations

Usage examples of alleles.

I told you the original intention of this device: to let parents pick and choose from the alleles they could offer a child.

She saw how she could change the chromosomes, how she could rearrange the pairs of alleles on each one.

Genes are the secret masters and a particular combination of alleles, a particular gene, or more than one possibly, comes into being occasionally to rule all the others, for what purpose we can only guess.

When we look at the molecular-genetic basis of life, all we can find are differences and singularities: multiple variations, competing alleles, aberrant particle distributions, unforeseeable sequence transpositions.

And as you know, alleles are what give us the foundation of evolution, through slight, various changes in species over time.

But there are so many alleles in common, the DNA profiles are so incredibly close, that we can only assume there is a third brother, and it is this brother who had sex with Susan.
