  3. Row 1, Col 1 What is dominant? The presence of this type of allele Will mask the presence of another Type.

  4. 1,2 What are genes? The chemical factors that determine traits

  5. 1,3 T t TT Tt T Tt TT T What is all tall? What is the phenotype of the offspring?

  6. 1,4 BR Br bR br BR Br X bR br What is bbRR? Genotype in square X

  7. 1,5 What is polygenic traits? Variation in human skin color is a result of

  8. 1,6 What is 100%? If two snapdragons show incomplete dominance for flower color and a gardener crosses a red flower with a white flower, what percentage of the offspring would be pink?

  9. 2,1 What the allele for tall is dominant? When Gregor Mendel crossed true-breeding tall plants with true breeding short plants, all of the offspring were tall Because ____.

  10. 2,2 What is homozygous? Organisms that have two identical alleles are ___

  11. 2,3 T t TT Tt T Tt TT T What is TT and Tt? The genotype(s) of the offspring

  12. 2,4 BR Br bR br BR Br X bR br What is White, rough hair? The phenotype of the offspring in square X

  13. 2,5 What is incomplete dominance? A situation in which one allele For a gene is not completely Dominant over another allele For that gene.

  14. 2,6 What is 40? A body cell of a pigeon has 80 chromosomes. If a pigeon lays an unfertilized egg, how many chromosomes will the egg have?

  15. 3,1 Who is Gregor Mendel? Who concluded that traits are Inherited by the passing of Factors from one generation to the next?

  16. 3,2 What is cross two true-breeding plants with different traits? How you get a hybrid

  17. 3,3 What is 1:2:1? When two heterozygous tall pea plants are crossed, The expected genotype ratio of the Offspring is

  18. 3,4 BR Br bR br BR Br X bR br What is 1/16? The fraction of the offspring that will have white, smooth hair

  19. 3,5 What is codominance?? A cross of a red cow (RR) With a white bull (WW) Produces all roan offspring (RW) This type of inheritance is called

  20. 3,6 What is dominant? A plant breeder crossed two red roses, 78% of the offspring had red flowers and 22% had white flowers. The allele for red flowers is most likely ___

  21. 4,1 What is inheritance of traits? Gregor Mendel used pea plants to study ____

  22. 4,2 What is incomplete dominance? A cross between a chicken with spotted feathers and a chicken with black feathers produced only chickens with feathers that had an intermediate, blue-gray color. What is this pattern of inheritance?

  23. 4,3 What is 50% y y Y y What percent of the offspring will have yellow seeds if Y is yellow?

  24. 4,4 What is 9:3:3:1? What is the phenotype ratio when you perform the following dihybrid cross RrYy x RrYy Where R: round; r: wrinkled Y:Yellow; y: green

  25. 4,5 What is 50% white and 50% pink? The color of the offspring’s Flowers if you perform a Test cross between a pink Snapdragon and a white one.

  26. 4,6 What is 25%? Both members of a couple are carriers of cystic fibrosis, a recessive disease. What is the chance that they will have a child with cystic fibrosis?

  27. 5,1 What is T from tall parent and t from short parent? When Mendel crossed a tall Plant with a short plant, what Alleles did the offspring inherit from each parent

  28. 5,2 What is the principle of independent assortment? The principle that states that during gamete formation genes for Different traits separate without Influencing each other’s Inheritance.

  29. 5,3 What is meiosis or sexual reproduction? A biologist observed several Different colors of fur in a Population of wild rabbits. This process contributes to the Variation of fur color

  30. 5,4 What is all are round, yellow? If pea plants that are homozygous For round, yellow seeds (RRYY) Were crossed with pea plants that Are heterozygous (RrYy) what Are the expected phenotypes Of the offspring?

  31. 5,5 What is RW? If red and white flowers are Crossed to make pink, what is the Genotype of the pink flowers?

  32. 5,6 The number of chromosomes in a gamete is represented by this symbol. What is N?
