35) Which of the following corectly states Mendels Law of Dominancersxpressed any When a trait is determined by two inheritance factors, one of a. factors i time it is present in the genome b. Inheritance factors segregate themselves and into the gametes c Inheritance factors for different traits segregate themselves into di rank rent gametes independently of each other inheritance is wrong: the units of inheritance behave more like particles. 36) What does homozygous mean? a. An organism that has only one of each type of chromosome b. An sm that contains two copies of the same allele for a given gene c. An organism that contains two different alleles for a given gene d. Genetically identical offspring 37) You're breoding a type of plant that can have cither pink or purple flowers (purple is dominant). What would you expect the offspring to look like if you crossed a true-breeding purple-flowered plant with a truc-breeding pink-flowered plant? a all purple-flowered offspring b. purple-flowered and 4 pink-flowered c. all pink-flowered offspring d. ¾ pink-flowered and ¼ purple-flowered 38) What would you expect the result of self-pollinating the F1 of the previous cross to be? all purple-flowered b, ¾ purple-flowered and ¼ pink-flowered c. all pink-flowered offspring d. pink-flowered and 4 purple-flowered 39) Which of the following correctly states Mendel's Law of Segregation? a. When a trait is determined by two inheritance factors, if the other is present in the genome. b. Inheritance factors segrega c. Inheritance factors independently of each other. one of those factors is expressed even te themselves and into the gametes randomly for different traits segregate themselves into different gametes d. Blending inheritance is wrong: the units of i is wrong: the units of inheritance behave more like particles. 40) We perform a test cross by crossing a tall plant with a short plant, and half the offspring were tall and the other half were short (tall is dominant). What is the genotype of the parents? d. Tall-Tt; short-Tt. 41) You cross a guinea pig with black, curly hair with a guinea pig with brown, straight hair and a. Tall TT; short- c. Tall Tt; short - tt b. Tall TT; short-Tt. all the offspring have black, curly hair indicating that black and curly are both dominant traits. What result would you expect if you crossed two of the Fls? a. All the offspring would have black, curly hair. b. 9/16 black and curly, 3/16 black and straight, 3/16 brown and straight, 1/16 brown and curly d. 9/16 black and curly, 3/16 black and straight, 3/16 brown and curly, 1/16 brown and straight c. ¾ black and curly, ¼ brown and straight
