ETHC 210 EXAM 4 • Question 1 3 out of 3 points Considering color detection humans are classified as (hint: How many primary colors can we see)? • Question 2 3 out of 3 points The mechanism of genomic imprinting involves: • Question 3 3 out of 3 points A color blind father married to a non-color blind mom (non-carrier of colorblindness) can produce a color blind son. • Question 4 3 out of 3 points In general there is no male-to male transmission of X-linked traits. • Question 5 3 out of 3 points In mother’s who are carriers for colorblindness even though they are not color blind some of their individual eye cone cells can express the trait. Also in female Calico cats the genes which produce color are found on the X chromosome and each hair cell expresses one X allele or the other giving rise to a random pattern of color in their fur. In both cases this is an example of: • Question 6 3 out of 3 points Biologically gender is determined genetically at; • Question 7 3 out of 3 points Which of the following hunger response hormones increases appetite? • Question 8 3 out of 3 points This famous discoverer of the DNA structure made racist comments in the 1990s based on the idea that certain people groups were biologically inferior. • Question 9 3 out of 3 points Which of the following hunger response hormones decreases appetite but increases digestion? • Question 10 3 out of 3 points Genomic imprinting has implications for understanding early human development. It suggests that for mammals, two opposite sex parents are necessary to produce a healthy embryo and placenta. • Question 11 3 out of 3 points A mutation in the LDL receptor gene can cause a dramatic rise in serum cholesterol. • Question 12 3 out of 3 points Which of the following is true about the rare condition of males who are XX and females who are XY: • Question 13 3 out of 3 points Body weight is controlled primarily by one gene. • Question 14 3 out of 3 points Even though Mendel’s laws are very helpful to understanding genetics, simple mendelian genetics does not explain well most of genetics because; • Question 15 3 out of 3 points Research studies which try to show a physiological or genetic basis for homosexuality have focused on a gene called Xq28 and the size of a certain brain region. • Question 16 3 out of 3 points According to some genetic researchers, the palindromic and repetitive sequences found in the Y chromosome. • Question 17 3 out of 3 points The human male is considered hemizygous for X-linked traits, because he only has one set of X-linked genes. • Question 18 3 out of 3 points Cardiovascular disease affects: • Question 19 3 out of 3 points Which of the following is true about the “X” and “Y” chromosomes? • Question 20 3 out of 3 points Simple mendelian single gene genetics explains skin color. • Question 21 3 out of 3 points Melanocytes contribute to skin color; • Question 22 3 out of 3 points The SRY gene found on the X chromosome causes the unborn baby to develop into a girl. • Question 23 3 out of 3 points For treatment of heart disease statin drugs are used to; • Question 24 3 out of 3 points In the U.S. the “sex ratio” of males to females drops significantly from birth to age 65. • Question 25 3 out of 3 points More than 100 genes affect pigmentation in skin hair and irises.
