There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.
How many different types of gametes can a BB genotype create?
Each gamete contains a single copy of every chromosome, and each chromosome contains one allele for every gene. Therefore, each allele for a given gene is packaged into a separate gamete. For example, a fly with the genotype Bb will produce two types of gametes: B and b.
What are the types of gametes that can be produced by an individual with the genotype TtGg?
Each parent produces one kind of gamete with an allele for each trait. The gametes are TG and tg. The F1 generation would all be the same, tall and green with a TtGg genotype. The F1 individuals can produce 4 different types of gametes: TG, Tg, tG, tg.
How can you tell how many gametes a genotype can produce?
The number of gametes produced by a specific genotype is calculated by the formula 2n, where n= number of heterogeneous alleles present in the genotype. Here, the given genotype consists of two heterogeneous alleles Aa and Bb while CC is homozygous. So, it can produce 22 = 4 types of gametes.
What is an example of phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
How many different gametes can be produced from the YY SS TT genotype?
21. How many different gametes can be produced from the Yy Ss Tt genotype? Write the all out. There is 8 different combinations which are: YST,Yst,YsT,yST,ySt, ysT and yst 22.
