A new type of cat coat color has officially been discovered. Named salmiak, or ‘salty liquorice,’ the cats have hair strands that start out black, and become white the further they grow from the ...

A new study from deCODE genetics and collaborators is the first to uncover a strong recessive component in Alzheimer's disease. deCODE genetics/Amgen, and collaborators from Iceland, U.S., UK ...

If individuals in the group tend to marry within it, there's a greater likelihood that the recessive genes of the founders will come together in the cells that produce offspring. Thus diseases of ...

In its simplest form, a test cross is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype (and phenotype).

The relationship of genotype to phenotype is rarely as simple as the dominant and recessive patterns described by Mendel. As opposed to partial dominance, codominance occurs when the phenotypes of ...

Sickle Cell disease is an autosomal recessive disorder that causes anemia, joint pain, a swollen spleen, and frequent, severe infections. It illustrates balanced polymorphism because carriers are ...
