Answer: alleles
Explanation:
Alleles are different forms of a given gene. Alleles are mutated forms of a given gene which controls a particular trait. For instance, the gene that codes for hemoglobin is denoted with the letter A but the gene has another variant denoted by S. In abnormal hemoglobin S (sickle hemoglobin), glutamate is replaced by valine at position 6 in the amino acid sequence of the two beta chains of hemoglobin. This change in the amino acid sequence causes the red blood cells to have a sickle shape resulting in sickle cell disease. Therefore hemoglobin A and S are alleles of a given gene.
Androgenous behaviors is not solely the product of biological sexual
differences, such as the ability to bear children. It is also regarded as product of evolution
and natural selection where an individual may be androgynous, displaying feminine and
masculine characteristics or traits based on one’s gender identity and learned
gender role. This can be made possible through the ongoing social interactions
that individuals have with each other.
