ok..quickie genetic lesson..
we will use "R" to represent the dominant normal gene for blizzard
we will use "T" to represent the dominant normal gene for patternless
we will use "r" to respresent the recessive gene for blizzard
we will use "t" to represent the recessive gene for patternless
Each gene has two active parts to its make up.
the blizzard has two recessive genes for blizzard (noted rr)
the patternless has two recessive genes for patternless (noted tt)
the genotype for the blizzard would look like this rrTT . the rerason for this is beacuse the blizzard gene is expressed and has no patternless genes that we know of, so the place where the patternless genes would exist is taken up by two normal domainat genes (noted TT)
The genotype for the patternless would look like this RRtt . The reason for this is because the patternless gene is expressed and has no blizzard genes that we know of, so the place where the blizzard genes would exist is taken up by two domainat genes. (noted RR)
Assuming the male is blizzard and the female is patternless each gecko gives up half his genetic code.
For the male which is blizzard(noted as rrTT), he gives up half its genetic code (being one "r" and one "T"
For the female which is patternless (noted as RRtt), she gives up half of her genetic code (being one "R" and one "t"
so now we have the following genes: "R" "t" "r" "T"
now we pair them together (remember sperm and egg joining from science class)giving us a combination of "RrTt"
now it takes two recessive genes (lowercase letters) to express a certain abnormality or recessive trait. this is called homozygous. If two are not present, then the recessive gene cannot be displayed and the dominant normal gene is displayed. when there is one normal domiant gene and one recessive gene, this is referred to as heterozygous, meaning that the individual carries the rescessive gene but does not display it..
your end result is a gecko with a genotype of "RrTt" meaning it carries the genes for blizzard and patternless but it cannot display them..
since it cannot dispaly them , they take the appearance of a normal gecko but are heterzygous for the genes or patternless and blizzard.
For clarity, genotype is the expression of genes using letters, phenotype is how the animal looks on the outside.
i hope this helps.. email me with any questions... also feel free to copy and paste this for other forums and/or yourself , but please don't copy this info for your website..write your own..
