A 3D pattern matching algorithm for DNA sequences

Meiosis notes
... ◦ This means that there are 2 copies of every gene. • Diploidy is useful because 2 copies of every gene means that there a backup copy if one gets mutated. ◦ Mutations are very frequent in the cells of large organisms. We wouldn’t survive with just one copy of each gene. 2. The Problem of Doubling • ...

... In males, a defective allele for any of these genes results in colorblindness, an inability to distinguish certain colors. The most common form, red-green colorblindness, occurs in about 1 in 12 males. Among females, however, colorblindness affects only about 1 in 200. In order for a recessive allel ...
