IMO, het lesser and het mojave makes it sound like two independent gene pairs, one made up of a lesser gene and a normal gene and the second made up of a mojave gene and a normal gene. Either lesser/mojave or het lesser/mojave sweems acceptable to me. Best of all is "a gene pair made up of a lesser gene and a mojave gene."
Please reread the definitions of homozygous and heterozygous in my earlier post. Whether a normal gene is present is irrelevant. All that matters is whether the two genes in the gene pair are the same or different.
Part of the quote reads, "A lesser/mojave BEL animal therefore, as we know, can only pass on either the lesser or mojave gene to it's offspring." That is true. A lesser/mojave ball python produces two different types of sperm (or eggs). One type has a mojave gene and the other type has a lesser gene. A het albino ball python also produces two different types of sperm (or eggs). One type has a normal gene and the other type has an albino gene. A homozygous albino ball python only produces one type of sperm (or egg). All have an albino gene. The number of types of sperm (or eggs) tells us whether a gene pair is homozygous or heterozygous. So a lesser/mojave ball python has a heterozygous gene pair.
So a gene pair made up of two Russo genes or two mojave genes is het leucistic? This does not compute.
