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.

- The woolly hair case. An inherited trait among Norwegians causes affected individuals to have very wavy hair, not unlike that of a sheep. The trait, called woolly, is very evident when it occurs in families: no child possess woolly hair unless at least one parent does. Imagine you are a judge, and you have before you a woolly-haired man suing his normal-haired wife for divorce because their first child has woolly hair but their second child has normal hair. The husband claims this constitutes evidence of his wife’s infidelity. Do you accept his claim? How is the trait inherited in the family? Justify your decision with your explanation of the inheritance of the condition in this family.Part II. Solving Genetics Problem. Do what is asked. Show your solution. A. Monohybrid Cross 2. Long ears (E) are dominant to short ears (e). a. What is the trait in this scenario? b. What are the two alleles in this scenario? c. A man is homozygous dominant. What is his phenotype? d. A woman's genotype is EE. What is her phenotype? e. A cross occurs between a homozygous recessive male and a heterozygous woman.... What percent chance will their first child have long ears? What percent chance will their fifth child have long ears? -Keeping it in the family!”- How do you think consanguinity is increasing the risk factors of genetic disorders? Explain with examples (at least two). It won’t be possible to change the tradition all of a sudden. If you are a clinical geneticist, how you will be managing this type of community?

- INCOMPLETE DOMINANCE. All of the traits in these problems show incomplete dominance. Work these as you did the other monohybrid crosses, but interpret your results with the rules for incomplete dominance. 1. In snapdragons, flower color shows incomplete dominance. Red color is dominant to write color. What kind of offspring could result from Parent 1 being heterozygous and Parent 2 have a white flower color? Trait:Multiple Alleles- Blood Types 1. Blood Type is controlled by 3 alleles: What are they? allele is recessive alleles are codominant, and in homozygous condition results in O blood group. 2. and 3. What are the genotypes possible for a person who has: A blood? B blood? O blood? AB blood? 4. A man with type AB blood is married to a woman also with type AB blood. Show the cross. What proportion of their children will have: A blood? B blood? O blood? AB blood? 5. A man has type B blood (genotype I"I") is married to a woman with type O (ii) blood. Show the cross. What proportion of their children will have: 1. A blood? 2. B blood? 3. O blood? 4. AB blood? 6. A woman with type A blood (genotype IAi) is married to a type B person (genotype I®i). Show the cross. What proportion of their children will have: A blood? B blood? O blood? AB blood?You are a studying the genetic basis of horn color in unicorns. Gene C determines the color of pigment destined for the horn by converting a pink precursor into a purple pigment. C- individuals make purple pigment whereas cc individuals accumulate pink precursor. Gene D ensures the deposition of the pigment into the horn cells, such that D- individuals have a colored horn (purple or pink), whereas dd individuals have a white horn. You breed two purple horned unicorns to each other (CcDd). Assuming Gene C and Gene D are unlinked, what is the probability that the baby unicorn has a purple horn? Please express your answer to 2 decimal places (e.g. 0.69).
- True or false? Some humans are genetically modified.Determining Gene Order 1. We want to map the distance between genes E (tall height), B (blue flower color), and G (thick stalk).

I have been denied/rejected two times on this problem. I need someone to help me calculate the “G5 Allele Frequency” I have included all the information in the picture and I put a red box around the section I need help with. The instructions only show me how to calculate the “Frequency G5” but NOT the “G5 Allele Frequency”. any help? Pls stop rejecting me and just try to help me? Pls
