Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
Question
I need help with this please. Thank you
![In a human population, the following genotypic frequencies were observed in the ABO blood type:
- AA: 0.09
- BB: 0.04
- AI: 0.30
- BI: 0.20
- AB: 0.12
- II: 0.25
### Hints for the Questions Below:
- Blood type A = genotypes AA and AI
- Blood type B = genotypes BB and BI
- Blood type AB = genotype AB
- Blood type O = genotype II
For part E: Use the equation for determining allele frequencies:
\[ A = \frac{2(AA) + Aa}{2 \times \text{population size}} \]
Apply this to genotypic frequencies rather than population abundances.
### D. Calculate the Phenotypic Frequencies:
- Frequency of people who are blood type A =
- Frequency of people who are blood type B =
- Frequency of people who are blood type AB =
- Frequency of people who are blood type O =
### E. Calculate the Allelic Frequencies for this Population:
- Frequency of the A allele =
- Frequency of the B allele =
- Frequency of the i allele =
To solve these questions, utilize the given genotype frequencies and apply the genotype-to-phenotype relationships outlined above. For allele frequencies, use the frequency of each genotype involving the allele and follow the provided equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1aad3133-cc5f-4a6c-993a-a852e3d1eb41%2F537d33b9-a9fb-480c-8d38-b061da3cd399%2Fku5vzn_processed.png&w=3840&q=75)
