You can still have freezing temperatures at night in April, but the daytime temperatures can be near perfect. May is probably ideal for the weather, although you'll encounter some rain in 13 days of the month. Fall is another good time to go to Florence.

From Wikipedia, the free encyclopedia. A heterozygote advantage (heterozygous advantage) describes the case in which the heterozygote genotype has a higher relative fitness than either the homozygote dominant or homozygote recessive genotype. common example is the case where the heterozygote conveys both advantages and disadvantages, while both homozygotes convey a disadvantage. A well-established case of heterozygote advantage is that of the gene involved in sickle cell anaemia.
