How are Alleles represented in your Genotype? A) They are a form of a trait that is represented by an uppercase or lowercase letter to show if they are dominant traits or recessive traits. B) They are ordered from most common to least common. C) They are ordered by which trait you inherited from your mother followed by the trait you inherited from your father. D) They are represented by a number to signify which chromosome they come from. Show Answer Correct Answer: A) They are a form of a trait that is represented by an uppercase or lowercase letter to show if they are dominant traits or recessive traits. 10. What is a gene map?

C) An organized layout of the relative locations of each gene on a chromosome. D) A set of directions folded in multiple ways that chromosomes use to navigate through a cell rather than stopping and asking for directions. Show Answer Correct Answer: C) An organized layout of the relative locations of each gene on a chromosome. 11. Which represents the genotype of a homozygous condition? A) Bb. B) BC. C) Bb. D) Bc.

Show Answer Correct Answer: D) Dominant alleles from either the father or the mother, or both. 17. Purple flower is dominant to white flower color. Yellow seeds are dominant to green seeds. Two parent pea plants are crossed that are both heterozygous for flower color and seed color. What would be the genotypes for both parents? A) Ppyy, Ppyy. B) Ppyy, ppyy. C) PpYy, PpYy. D) Ppyy, PPYY. Show Answer Correct Answer: C) PpYy, PpYy. 18. Mitosis and meiosis both produce new cells through cell division. However, the division process differs due to the kind of cell being produced. How is meiosis different from mitosis? A) Mitosis produces 4 daughter sex cells with half the number of chromosomes which divide twice.
