Set 1

  1. Which of the following hunger response hormones decreases appetite but increases digestion?

  3. Daughters can inherit sex linked recessive disease if:
  4. A color blind father married to a non-color blind mom (non-carrier of colorblindness) can produce a color blind son.
  5. 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:

  21. The mechanism of genomic imprinting involves:
  22. At the chromosome levels males are homogametic.
  23. The human male is considered hemizygous for X-linked traits, because he only has one set of X-linked genes.
  24. Which of the following are polygenic multifactorial traits?
  25. More than 100 genes affect pigmentation in skin hair and irises.

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:
  6. Melanocytes contribute to skin color;
  7. Cardiovascular disease affects:
  8. Epigenetics plays a role in controlling weight gain as shown in experiments with genetically determined obese mice. Obese female mice were able to decrease obesity in their offspring by eating a diet rich in:

  15. A color blind father married to a non-color blind mom (non-carrier of colorblindness) can produce a color blind son.
  16. In the U.S. the “sex ratio” of males to females drops significantly from birth to age 65.
  17. The mechanism of genomic imprinting involves:
  18. Body weight is controlled primarily by one gene.
  19. The SRY gene found on the X chromosome causes the unborn baby to develop into a girl.
