The answer should be allele(s).
Alleles are alternative forms of genes. For example in eye color, there is brown eye allele that produces brown eyes or blue eye alleles that produces blue eyes.
However, note that there may be dominant or recessive alleles. Dominant alleles are always expressed, meanwhile, recessive allele is only expressed when there is no dominant allele existing.
An example is let say brown eye allele is dominant and blue eye allele is recessive. The eye gene is controlled by 2 alleles. If I had one brown eye allele and 1 blue, my eyes will be brown, because brown eye allele is dominant.
The correct answer is letter C. Eugenics is the science of improving hereditary qualities. It came from the Greek word, eugenes, which means "well-born race, stock, kin." This is a practice of beliefs that aimed at improving the quality of genes of a particular human population. Much like the way that Spartans bred their offsprings where they made sure that only the best quality genes are present in their population.
