Lab Exercises: In these exercises, you will learn to use the Punnett square to determine geno- typic and phenotypic outcomes for monohybrid, dihybrid, incomplete, codominant, epistatic, and sex-linked traits.

PLease help, double and triple check your answers, im using this to study, these questions are NOT graded they are PRACTICE problems. Please help with all 4 parts of this question!!!!!!! A. Your maternal grandpa is colorblind but both your mom and dad are not affected. What are the chances of your sister being colorblind? What are the chances of your brother being colorblind? (Colorblindness is X-linked recessive) B. Regarding the problem above, if your sister’s husband is colorblind, what are the chances that their first son will be colorblind? C. Two genes, A and X, exhibit incomplete linkage. The frequency of each parental gamete (AX and ax) is 45%. What is the approximate frequency of the Ax gamete? D. There are three genes located in the gene order A--B--C on a chromosome. Would you expect the recombination frequency to be higher between A and B or A and C?
Practice Problem 2: Having a hairline with a widow's peak is dominant and a straight hairline is recessive (W = widow's peak; w = straight hairline). Hint: To avoid confusing alleles, use a bar over the lowercase letter OR chose a letter that doesn't look the same upper and lowercase (instead of "W" and"w" you could use "D" and "d"). Cross: A man with a straight hairline marries a woman homozygous dominant for having a widow's peak. What is the genotypic ratio and the phenotypic ratio for this cross?

Probability of red carnation plant? _% Probability of yellow carnation plant? -_% CODOMINANCE In some chickens, the gene for feather color is controlled by codominance. The allele for black is (BB) and the allele for white is (ww). The heterozygous phenotype is known as erminette or spotted (BW). If a farmer breeds the black feather chicken to an erminette chicken. What is the probability of producing a white, black and erminette feather chicken? INCOMPLETE DOMINANCE For instance, in snapdragons, red (R) and white (W) are two possible flower colors. However, when a red and a white flower are crossed, instead of one color being dominant over the other, they blend together and form…

EXERCISE 6 HARDY-WEINBERG EQUILIBRIUM Work in a small group or alone to complete this exercise. In human population X, consider the simple Mendelian trait for freckles. F is the dominant allele and f'is the recessive allele. Individuals who are homozygous dominant (FF) or heterozygous (F) for the trait express freckles. Individuals who are homozygous recessive (ff) for the trait do not express freckles. In this population, 30% (0.3) of the alleles are recessive (f ) and 70% (0.7) are dominant (F). 1. Use the Hardy-Weinberg equation to determine the genotype frequencies we should expect in the next generation. Be sure to show your work. 2. You have collected data on the observed genotype frequencies of the next generation. They are 60% FF, 30% Ff, and 10% ff. Based on these observations and your expectations, is this trait currently evolving in this population? Why or why not?
