(Use binomial formula) 5 pointsProcedure: 1. Draw a Punnett square which shows the inheritance of the sex chromosomes. Represent the female sex chromosomes with XX and the male sex chromosomes with XY. Guide Questions: a. What will be the sex of a child produced when an egg is fertilized by a sperm that has a Y chromosome?. b. What type of sperm must fertilize an egg to result in a female child? c. Based on this Punnett Square, what percent of children would you expect to be male? d. What sex chromosome is present in both male and female? e.

- Task #3 Impact of allelic difference: The receptor protein encoded by the recessive m allele sequence cannot bind its hormone partner, and as a result the fur pigment eumelanin is not effectively produced. Briefly explain how one amino acid change might impact the function of the receptor protein. Task # 4 Genotypes and Phenotypes: The Mc1r gene is located on chromosome #16 in mice. Mice are diploid so every somatic cell has two copies of the Mc1r gene. Since there are two Mc1r alleles there are three possible genotypes: MM, Mm and mm. M=dark pigment m=less pigmentParental generation: an inland mouse (MM) mates with a beach mouse (mm) A. What is the genotype of the F1 offspring? ________B. If this trait exhibits simple (Mendelian) dominance, circle the phenotype expected for the F1 fur color: dark pigment / medium pigment / less pigment Observed phenotype: F1 actually have medium pigment. Initially this looks like blending, but it is not. M and m are discrete units. This observation…Question: On the basis of Mendel's hypothesis and observations, predict the results from the following crosses in garden peas: (a) a tall (dominant and homozygous) variety crossed with a dwarf variety: (b) the progeny of (a) selfed; (c) the progeny from (a) crossed with the original tall parent; (d) the progeny from (a) crossed with the original dwarf-parent variety.Sample problems related to non Mendelian inheritanceRead, analyze and answer completely the following problems: 1. Explain why it is possible for the proband in the following pedigree to have children of blood types A, B, and AB. Considering epistatic genes, what are the possible genotypes of II-2? 2. Agouti (A) is wild type and produces alternating bands of pigment on each hair. Black (a) is recessive to agouti. A mutation on gene B (recessive b) can eliminate all color. In a cross between agouti (AABB) and albino (aabb) mice, what genotypes, phenotypes, and proportions are expected in the offspring in F1 and F2 generations?
- Application Instructions: Before Mendel and his results were fully accepted, there were many theories that were proposed that tried to explain how traits were passed on from one generation to another. In the space provided, list down the important points of each theory. Hippocrates': Brick and Mortar Theory Aristotle: Hereditary Elements in Blood Darwin: Theory of PangenesisEXERCISE 5 MENDELIAN TRAITS IN HUMANS 1 While most human traits are polygenic, the traits in the chart below have traditionally been considered Mendelian traits. More recent research has disputed the single-gene nature of some of these traits, but for the purpose of this exercise, assume that the following traits are Mendelian. Work with a partner to help each other determine your own phenotypes and possible genotypes for these traits. Write your answers in the chart. (Note: Refer to the table on p. 62 for information about these traits.)
