Hello guys just double checking the answers my biology genetics study guide. Please go ahead and answer ALL the questions you see below, if you can't answer all then PLEASE let someone else do them! High rating only given to ALL questions complete (questions 1 I posted the handout for it below)

QUESTION 1 For the pedigree shows in handout 1, the mutation may be O dominant autosomal recessive autosomal X-linked recessive O A, B or C O A or B only QUESTION 2 Gregor Mendel conducted a testcross for pea color in which yellow is dominant to green in order to determine the genotype of a particular pea plant. If the individual plant being "tested" by Mendel was heterozygous, then the resulting offspring would likely be: all yellow O all green 1/2 yellow, 1/2 green 3/4 yellow, 1/4 green 1/4 yellow, 3/4 green QUESTION 3 Allele D is dominant to allele d. A heterozygote is crossed with another individual of the same genotype. Sixteen (16) offspring are produced from this cross. In theory, how many of the offspring will display the dominant phenotype? 16 om - QUESTION 4 A true-breeding cow with red hair is crossed with a true-breeding cow with white hair and a red and white spotted calf is born. This result suggests that the allele for red hair is white hair in cows. completely dominant to completely recessive to codominant with incompletely dominant to epistatic to QUESTION 5 The genes for red-green colorblindness and hemophilia are both located on the human X-chromosome. Thus, these genes belong to the same linkage group are X-linked assort independently of one another both a and b both b and c

Answer 1

Please give a thumbs up.
Question 1: for the given Pedigree the mutation may be dominant autosomal or recessive autosomal. Show the answer is option E.
Question 2: for a test cross with a heterozygous plant leads to equal ratio of both the colours so the answer is option C.
Question 3: for heterozygous cross with same genotype the dominant allele is found in 75% of them so answer is option B ....12.
Question 4: if both the trades are appearing equally then and they are codominant with each other. The answer is option C.
Question 5: since they both are located on X chromosome they are excellent and also because they are located on a single chromosome they belong to the same linkage group. So the answer is is option D......both a and b.
