knowing which genes play a role in hair and eye color variation can help us understand why some hues are more prevalent than others. Keep reading to find out the rarest hair color, the rarest eye ...

The OCA2 gene determines how much brown pigment is ... The exact cause remains to be determined, but scientists do know that eye color began to change long before recorded history began.

Sturtevant examined recombination events between B (body color), CO (two eye color genes that were closely linked), and R (rudimentary wings), and compared the frequencies of crossover events.

For example, can the alleles for the body color gene (brown and black) be mixed and matched in different combinations with the alleles for the eye color gene (red and brown)? The simple answer to ...

Mendel read Darwin with deep interest, but he disagreed with the blending notion, hypothesizing instead that traits, such as eye color or height ... we now call a gene (though Mendel never used ...
