What are the 2 types of genotypes?
A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ. The process of determining a genotype is called genotyping.
What is a genotype give 2 examples?
… A genotype is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.
How many genotypes does 2 alleles have?
Number of genotypes for a given number of alleles Given n alleles at a locus, the number genotypes possible is the sum of the integers between 1 and n: With 2 alleles, the number of genotypes is 1 + 2 = 3.
What is genotype AA?
The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive. In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”.
How do you get 2pq?
The percentage of heterozygous individuals (carriers) in the population. Answer: Since 2pq equals the frequency of heterozygotes or carriers, then the equation will be as follows: 2pq = (2)(. 98)(.
Who can genotype AA marry?
They refer to the hemoglobin gene constituents on the red blood cells. AC is rare, whereas AS and AC are abnormal. The compatible genotypes for marriage are; AA marries an AA — which is the best compatible, and that way, the couple save their future children the worry about genotype compatibility.
What is BB genotype?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB.
Can AS and SS marry?
AS and AS should not marry, there is every chance of having a child with SS. AS and SS shouldn’t think of marrying. And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.
Can AA get marry to SS?
The Cartesian product of sets as appeared in the interpretation of results. A shows that when two couples both with genotype AA, got married, their chance of having offspring with AA is certain and that of AS and SS is zero. When contracting marriages the two couples having both A’s alleles should be encouraged.
