Point Mutation
... Hutchinson-Gilford progeria syndrome The disease is caused by a small point mutation on a single gene known as LMNA. Almost all cases are caused by the substitution of only one base pair out of the approximate 25 000 DNA base pairs that compose the LMNA gene. This gene codes for the protein lamin A ...

The principle of independent assortment 1. explains the 3:1 ratio of phenotypes in the F2 generation of Mendel's dihybrid crosses. 2. states that a dihybrid cross is essentially equivalent to a monohybrid cross. 3. arises from the random alignment of different chromosomes at metaphase I of meiosis. ...
