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).
A diploid organism is heterozygous at a gene locus when its cells contain two different alleles of a gene. The cell or organism is called a heterozygote specifically for the allele in question, therefore, heterozygosity refers to a specific genotype.f both alleles of a diploid organism are the same, the organism is homozygous at that locus. If they are different, the organism is heterozygous at that locus. If one allele is missing, it is hemizygous, and, if both alleles are missing, it is nullizygous.
