27. Genetic Disorders 300 A child is born with Down syndrome. What is the most likely cause? A. The child was involved in a car accident causing brain damage. B. The child smokes and drinks a lot at a young age and catches Down syndrome because of the unhealthy lifestyle. C. A genetic mutation on the 21st chromosome occurred in the sex cells of one of the parents during meiosis. D. A genetic mutation on the 21st chromosome occurred in the cells of the child during mitosis.

28. Genetic Disorders 300 C. A genetic mutation on the 21st chromosome occurred in the sex cells of one of the parents during meiosis.

53. Final Jeopardy A genetic counselor has gathered the following information. *Bob and Helen have 3 children. *Bob and Helen have 1 son who has albinism, an inherited condition in which the skin does not have brown pigments. *Bob and Helen have another son and 1 daughter who do NOT have albinism. *Neither Bob nor Helen has albinism. *Albinism is neither sex-linked(only found on the sex chromosomes X orY), nor co-dominant. Is albinism controlled by a dominant allele or by a recessive allele?
