Birth rates have stayed roughly constant for many years. Their populations include many retired people. Infant death rates have remained constant. One point each. Mutations might not change the fitness of individuals carrying them.
Recessive alleles are necessarily more rare than dominant alleles.
The molecular clock hypothesis is based on the assumptions that mutation rates are constant and natural selection is unimportant. The average number of individuals per square kilometer will probably not represent the actual density each individual experiences. The exponential growth curve is S-shaped. Five points each. Polyploidy involves a multiplication of chromosome sets.
