Why can you possess traits neither of your parents have? The relationship of genotype to phenotype is rarely as simple as the dominant and recessive patterns described by Mendel. As opposed to ...

Deep within the cells of mice, a genetic arms race is unfolding between X and Y chromosome genes, battling for dominance in sperm. Researchers have now discovered how these gene families compete by ...

In this context, parental perceptions and behaviors may inadvertently solidify certain roles, such as "dominant" or "submissive," in twins' relationships. Interestingly, genetic similarity also ...

Genetics is the branch of science concerned ... gene behaviour in the context of a cell or organism (e.g. dominance and epigenetics), gene distribution, and variation and change in populations.

Both incomplete dominance alleles are shown with upper case letters in genetic diagrams, but the letters used are different. For example, feather colour in hens may be white, black or speckled (it ...

The tall allele is dominant and is shown as T. The small allele is recessive and is shown as t. Complete this Punnett square to show the possible allele combinations of the offspring produced when ...
