Title: Which of the following statements correctly describes the Chromosomal Theory of Inheritance? Post by: billyray on Jun 6, 2019 Which of the following statements correctly describes the Chromosomal Theory of Inheritance?
Select one: a. X and Y chromosomes determine whether an individual is genetically male or female. b. Homologous chromosomes separate independently during meiosis. c. Each person has two copies of the factors that determine our traits. d. The factors that determine our traits are found on chromosomes. Another Vulcan trait that is dominant over Earthling alleles is absence of adrenal glands (A). The genes for ear shape (P/p) and heart sidedness (R/r) are 20 map units apart on chromosome 7. The gene for adrenal glands (A/a) is on chromosome 3. If Mr. Spock fathers a child with an Earthling female, what are the chances that the child will have pointed ears and adrenal glands? Select one: a. 10% b. 25% c. 50% d. 20% Two genes called TE and X1 were studied in a lab. 45 out of 500 offspring from crosses involving these two genes had recombinant genotypes. What is the recombinant frequency of the genes TE and X1? Select one: a. 18% b. 4.5% c. 50% d. 9% Title: Re: Which of the following statements correctly describes the Chromosomal Theory of Inheritance?
