What are the possible genotypes of the offspring?
A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
How many possible genotypes are there for 5 genes?
The formula that predicts the number of genotypes from the number of genes is 3 to the power n.
| # of Genes | # of Genotypes |
|---|---|
| 1 | 3 |
| 2 | 9 |
| 5 | 243 |
| 10 | 59,049 |
How many genotypes are possible with 4 genes?
10 genotypes
4 alleles there are 1 + 2 + 3 + 4 = 10 genotypes.
What are the possible genotypes and phenotypes of the offspring?
The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. A genotype is the genetic makeup of the organism. This is shown by the three genetic conditions described earlier (BB, Bb, bb). The phenotype is the trait those genes express.
How many genotypes are possible at a locus with five alleles?
For five alleles (n = 5), we get 15 possible genotypes and five homozygotes. For eight alleles, there are 36 possible genotypes.
How many genotypes does a gene have?
Genotype is also used to refer to the pair of alleles present at a single locus. With alleles ‘A’ and ‘a’ there are three possible genotypes AA, Aa and aa. With three alleles 1, 2, 3 there are six possible genotypes: 11, 12, 13, 22, 23, 33. First we must appreciate that genes do not act in isolation.
Can a gene have 4 alleles?
A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual.
How are the genotypes of parents related to the offspring?
How are the genotypes of parents related to the genotypes and phenotypes of the offspring? The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
What is the difference between phenotype and genotype?
Genotype is the inherited genetics from the parent generation, and phenotype is the physical expression of that gene. Added: Phenotype also includes the behavioral expression of the genotype.
How does natural selection affect the distributions of phenotypes?
The three ways that natural selection can affect the distributions of a phenotype are that organisms and their offspring have a variation in their phenotypes and genotypes, favorable variations survive and are passed on to offspring, and, organisms reproduce more offspring than could possibly survive. Can phenotypes OB produce genotypes As?
