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).
Homozygous and Heterozygous. If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous.Keep in mind that an organism can't simply be 'homozygous,' period.or example, the allele that gives rise to albinism is recessive, and the allele for normal pigment production is dominant. That means that a heterozygous individual with the genotype Aa, who has one copy of the normal allele and one copy of the albinism allele, would not be an albino.
