The white fur coat allele would be represented by an F (for “fur”) with a “W” subscript and a brown fur coat allele would be represented by an F with a “B” subscript.
What is W genotype?
White x Yellow. Parental genotypes. WW. ww (W = dominant allele; w = recessive allele) Parental gametes.
What does W mean in genetics?
The wild type (WT) is the phenotype of the typical form of a species as it occurs in nature. Originally, the wild type was conceptualized as a product of the standard “normal” allele at a locus, in contrast to that produced by a non-standard, “mutant” allele.
What does F stand for in genotypes?
One allele codes for purple flowers and is represented by the uppercase letter F, whereas the second codes for white flowers and is represented by the lowercase letter f. A varied population of sweet pea plants could therefore feature three possible genotypes at this locus: FF, Ff, or ff.
What is FF genotype?
Your Alpha-1 genotype is FF. This means that you have two copies of the F mutation in your Alpha-1 genes. This is a rare form of alpha-1 antitrypsin deficiency. The F mutation produces a dysfunctional alpha-1 protein product.
What does a selection coefficient of 0 mean?
The coefficient of selection is usually taken to be a measure of the extent to which natural selection is acting to reduce the relative contribution of a given genotype to the next generation. … If s = 0, the genotype is not selected against at all.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What letter represents the recessive gene?
Recessive alleles are denoted by a lowercase letter (a versus A). Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.
Why do genotypes have 2 letters?
The two letters in a genotype represent the pair of alleles. The uppercase letter represents the dominant allele and the lowercase letter represents recessive allele.
What is Diallelic?
diallelic Applied to a polyploid individual with more than two sets of chromosomes in which two different alleles exist at a particular gene locus.
What is FL FL mice?
Hi Priyankaa, HTT flox/flox (or HTT Fl/Fl) refers to the idea that the mice mentioned above have a knockin of the HTT gene in which portions of the gene are flanked by two Cre recombinase recognition sites.
What letter represents genotype?
Very quick rehash (review): genotype = the genes of an organism; for one specific trait we use two letters to represent the genotype. A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).
What does FL FL mean mice?
With tissue-specific Cre-lox KO models, the genotype of the mice that you generally want to evaluate is homozygous for your floxed allele (fl/fl) and positive for Cre (cre+). (Typically, only one copy of the cre transgene is required for efficient recombination.)
What is the genotype of RR?
The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above, a monohybrid cross is performed between plants that are heterozygous for round seed shape. The predicted inheritance pattern of the offspring results in a 1:2:1 ratio of the genotype.
What is the genotype ratio of TT and TT?
When cross takes place between Tt and tt two different types of alleles are form, Tt X tt = Tt, Tt, tt, and tt. The genotypic ratio for this cross is 1:1 and the phenotypic ratio is 1:1, where Tt is heterozygous dominant and tt is heterozygous recessive. This type of cross is a test cross.
