Snakes what does het mean

This is where it gets complicated and they can take three or more sets from the same, or closely related species. Ask biology. Homozygous: This is pair of identical Alleles that create a constant trait that will always be displayed. A purple flower will always produce more purple flowers unless it's bred with a non-purple flower, and then it's not Homozygous anymore. There are two "sub-types" of Homozygous organisms:.

Homozygous Dominant: Meaning that it is a pair of Alleles with a dominant trait this would be the purple flowers. Homozygous Recessive: Meaning that it is a pair of Alleles with a recessive trait. This would be if you bred an animal for the albinism trait to where the albinism trait was the dominant Allele.

Heterozygous: This is a pair of differing Alleles, of which only the more dominant Allele will be displayed. For example, if it is a pair of Alleles that determine hair color, and one would determine blonde, the other red, the hair color will be blonde because that is the dominant Allele.

But, the Allele for the trait of red hair still exists, and can be passed on to the next child to possible be matched up with the same allele, or one that's more recessive less dominant? The problem with pairing up Heterozygous Alleles, is that they can be infinitely complex which is why people devote their lifetimes to studying them , I've simplified it to where one Allele is dominant over the other, and that's basically how it works, but determining how they are dominant, and which ones are dominant, is a complicated study that's out of my area of expertise.

People devote lifetimes of effort into this area of study alone, just mapping out how Alleles are paired together and how they choose which one "wins". Hemizygous: This one's a bit more than I can explain.

From what I understand, it's when one of the Alleles gets removed, and there becomes a single trait leftover. It has something to do with the reason why men only have on 'X' and one 'Y' chromosome. Nullizygous: When two mutations that cause a loss of function pair up. Don't quote me on this. Phenotypes: This was mentioned in a comment, so I wanted to touch on it as best I could. It's a combination of the Genotype, which are the instructions that have been inherited from the Alleles, and how it's all been influenced by the environment.

Beware though, these two terms are pretty loose, and have been used interchangeably I think. To give a gross oversimplification for an example. A phenotype would be when a moth is colored brown, because it lives in the woods and the Alleles received were for that color, and also because all the moths with different colors got eaten so the only color that was left was brown. Matt's explanation pretty much covers the science of it.

As a more simplistic view, though, consider two snakes, a male and a female, both of which look "normal". Im probably confusing you more OldHag said:. Thoth Arachnopharoah Old Timer.

For a recessive trait you need both copies of the gene for it to show.

Homozygous means the 2 genes are the same. You will only typically see het used when talking about recessive morphs, because a recessive morph only visually shows in the homozygous form meaning having two copies of the gene. Aug 4, What does Het mean in a snake? When bred to other ball pythons showing or carrying the same recessive gene, the visible morph can be produced.

What does Het mean in boas? How do you know if a snake is het? There are no tests for it other than the test of time and breeding. It used to be thought that christmas and strawberry increased the amount of red pigment seen on the snake, but a different gene or genes has been shown to be the actual culprit of that, namely Red Factor or Red Coat.

Het stands for heterozygous which is the scientific term.
