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.
heterozygous. adj. 1. (Genetics) genetics (of an organism) having different alleles for any one gene Compare homozygous: heterozygous for eye colour. (ËhÉt Ér ÉËzaÉª gÉs).
Best Answer: Heterozygous is when you have 2 different alleles for a certain characteristic: e.g. You could have a gene for brown eye colour on one chromosome and a gene for blue eyes on the other. In this case the dominant gene of the 2 would be expressed in the individual. Homozygous dominant is when the 2 alleles are the same and they are the dominant form of the gene. e.g. 2 brown eye genes BB Homozygous recessive is when the 2 alleles are the same and are the recessive form of the gene bb.
