You were tasked to conduct a population genetic survey of a diploid insect population. You obtained tissue samples from 20 individuals, ran a starch gel electrophoresis, and stained the gel for lactate dehydrogenase. Below is the result of your gel electrophoresis. You found that there are three alleles and you decided to call them F, M, and S for their fast, medium, and slow mobility on the gel. please explain this in deep. 1) What is the M allele frequency in this population? A) 0.05 b) 0.25 c) 0.30 d) 0.4 e) 0.5 2)Following up the previous question, what is the observed SS genotype frequency in this population? a) 0.1 b) 0.2 3) 0.3 4) 0.4 5) 0.5
Codominance in blood types. If a male with type A blood (with genotype IAi) mates with a female having type B blood (with genotype IBi), what are the phenotypic ratios for the blood types of the offspring? ___ A : ___ B : ___ AB : ____ O Suppose that one parent has type AB blood, and the blood type of the other parent is not known. Describe how a child can (or cannot) have the following blood types: Type A Type B Type AB Type O
The most common allele of the β chain of hemoglobin in humans, ???,H⁢bA, has glutamic acid at the sixth position. Two different amino acid substitutions at the sixth position produce two variants, ???H⁢bS and ???,H⁢bC, of the sickle‑cell allele. The ???H⁢bS allele occurs when valine is substituted for glutamic acid, and the ???H⁢bC allele occurs when lysine is substituted for glutamic acid. To answer the question, refer to the amino acid table. Match the class of amino acid and the chemical property to each possible amino acid. Not all answers will be placed.
Please answer all parts along with the reason. I'll definitely give a like. Thank you in advance! 1A) From the cross Ab/aB x ab/ab, what is the recombination frequency if the progeny numbers are 17 AB/ab, 72 Ab/ab, 68 aB/ab, and 21 ab/ab? 1B)In human gene mapping, a LOD score is calculated to see if a gene causing a rare disease is linked to a known SNP. The LOD score is -4. This means that 1C) A three-point testcross is used to determine the order of three linked genes. The following crossover progeny result: single crossovers, double crossovers, and no crossovers. To determine the order, the no-crossover progeny must be compared to what other class of progeny?
Recessive epistasis: In a cross between fruit flies that are both double heterozygous for modifier gene and coat color, in the total offspring of 192, how many fruit flies have gray- coat, white coat, and black coat? A recessive allele blocks the expression of the coat color of fruit flies. Show your answer and solution.
Predispositions in populations. Assume that 10% of the members of a population will get a particular disease over the course of their lifetime. Genomic studies reveal that 5% of the population have sequences in their genomes such that their probability of getting the disease over the course of their lifetimes is 50%. What is the average lifetime risk of this disease for the remaining 95% of the population without these sequences?

VARIATIONS IN GENE EXPRESSION In humans, the glucose-6-phosphate dehydrogenase (G6PD) gene involved in sugar metabolism is X-linked. The dominant allele (G) codes for fast enzymes for normal cell functioning while the recessive allele (g) codes for slow enzymes, which are responsible for the reduced enzymatic activity of cells. However, the presence of slow enzymes has minimal effect in the overall functioning of heterozygotes, thus normal. Recessives, however, are more prone to oxidative reactions that speed up the cell damaging process, thus weak (but not lethal). If random inactivation occurs during dosage compensation, what would be the genotypes and phenotypes of the children of a heterozygous mother and a recessive father? Show COMPLETE cross.
