- As a genetic counselor, you inform Susan and John that a blood test for cystic fibrosis is available. Would you recommend genetic testing for Susan and John? Explain.arrow_forwardPart B 1. For the remaining characteristics, you will be looking at homozygous and heterozygous traits. Each trait will be determined to be homozygous recessive, homozygous dominant, or hetero- zygous. Letters representing the alleles will be given to you; the uppercase letter is always dominant and the lowercase letter is always recessive. If both dice rolled are even numbers, it indicates homozygous dominant alleles; if both are odd, it indicates homozygous recessive alleles; if one is odd and the other even, it indicates heterozygous alleles. 2. Eyebrows: Use the alleles "A" and "a" for this trait. Two separate brows are the dominant trait, whereas the unibrow (or one continuous brow) is recessive. 3. Eye shape: Use the alleles "R" and "r" for this trait. Round eyes are the dominant trait; almond shaped eyes are recessive. 4. Hitchhiker's thumb: Use the alleles "H" and "h" for this trait. Straight thumbs are dominant; Hitchhiker's thumbs (the curving upward of the thumb) are…arrow_forwardSuppose a woman who is a carrier (XNXN)marries a man who is colorblind (XnY). Is there any chance that they will have a male child with a normal color vision? What are the possible phenotypes? 大 A. No chance, 2 female carrier and 2 males colorblind B. Yes, 1 female carrier, 1 female color blind, 1 male with normal color vision and 1 male colorblind C. Yes, 1 female colorblind and 2 males with normal vision and 1 male colorblind D. Yes, 2 males with normal color vision and 2 females carrierarrow_forward
- Part 1: Make a three part process drawing (like a cartoon strip) to demonstrate Mendel's Principle of Segregation. Use two parents with homologous chromosomes marked with alleles "A" and "a". Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes (indicate when this happens), and c) gametes from each parent combine at random to form diploid offspring Part 2: Use the cross Aa x Aa and a Punnett square to demonstrate Mendel's Principle of Segregation. Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes and c) gametes from each parent combine at random to form diploid offspring. Part 3: Use homologous chromosomes marked with alleles "A" and "a" and a second pair of homologs marked with alleles "B" and "b". to demonstrate Mendel's Principle of Independent Assortment in cells in Meiosis. Indicate what phase this…arrow_forwardHi, I'm having trouble with my study guide for my upcoming genetics exam. If someone could please help with work shown and an explanation it would help so much! Thank you!! 2a. The pedigree below represents inheritance of rare condition. What pattern of inheritance is most consistent with the data? Assign alleles to all individuals to support your answer. If an allele is unknown, assign it a ? symbol. NOTE: Individuals whose phenotype or genotype cannot be determined are assumed to be unaffected and homozygous, unless otherwise indicated. 2b. In addition to the alleles you’ve indicated, describe 2 overall features of the pedigree that make it consistent with your chosen form of inheritance. 2c. Based on your mode of inheritance, what is the probability that the child of couple IV-4 x IV-5 will be affected? Show your work. attached is the pedigreearrow_forward3) Abraham is adopted.

I have trouble with correct position of the genesarrow_forwardI understand that Phenylketonuria, or PKU is recessive and that by looking at the pedigree analysis that Ryan and Natalie are mother/son, but I don't understand the genotypes for Max and Kate.

What are the genotypes of all six people in this family? NOTE: The ABO blood type gene has three alleles. IA and IB are codominant; i (for Type O) is recessive to both.arrow_forwardCan you please not type the answer can you write it on a paperarrow_forward
