However, dominance simply says which phenotype the heterozygote has. It is not, in itself, an advantage or disadvantage. Examples: • Huntington’s di ...

Species are recognized on the basis of their morphology (size, shape, and appearance) and, more recently, by genetic analysis. For example, there are up to 20 000 species of b ...
