  2. The set of alleles that an individual has is known as its

  3. GENOTYPE

  4. The physical traits that an individual expresses is known as the…

  5. Phenotype!

  6. If you cross two heterozygous individuals, the genotypic ratio is always this.

  7. What is 1:2:1?? YES!!!

  8. Which genotype do I breed an unknown genotype to in order to perform a test cross?

  9. Homozygous recessive

  10. In frogs, white bellies are dominant to yellow bellies. If a heterozygous frog is crossed with a yellow bellied frog, what are the chances of them having heterozygous offspring?

  11. 50%

  12. Colorblindness is this type of trait...

  13. Sex-Linked!!

  14. A child has inheritedan A allele from his mom, and an O allele from his dad. What blood type will the child have?

  15. Blood Type A Because Blood Type O is recessive!

  16. Give an example of one trait that exhibits codominance, recessiveness, and multiple alleles!

  17. Blood Types A, AB, B, O

  18. Bobby has hemophilia. What is the genotype of his mother?

  19. XCXc Bobby’s mother is a carrier.

  20. Bobby has Duchene Muscular Dystrophy.His Sister, Liza, is completely normal.Bobby is the only one in his family with this disorder.What are the genotypes of his parents?

  21. Mom’s genotype is XDXd (Carrier) Dad’s genotype is XDY (Normal) Bobby inherited the gene for muscular dystrophy from his mother.

  22. The branch of biology that deals with heredity is known as this...

  23. GENETICS!!!

  24. This type of cross involves one pair of contrasting traits

  25. A monohybrid cross is a cross that has one pair of contrasting traits

  26. Match the appropriate word to BOTH definitions: 1. An organism that has two identical alleles for a trait is known to be this. 2. The physical appearance that you express is based on your __________________.

  27. 1. Homozygous 2. Genotype

  28. 1. A type of trait that is determined by a gene located on the X chromosome. 2. A person who is heterozygous for a recessive disorder

  29. 1. Sex linked trait 2. Carrier

  30. Match all 3 correct words to the definition for all points: 1. Different versions of genes are known as these. 2. A procedure that tests whether or not an individual is homozygous for a trait

  31. 1. Alleles 2. Test Cross

  32. A yellow Hoo is crossed with a Hoo that is yellow with red polka dots. This is most likely an example of...

  33. Codominance

  34. A white carnation is crossed with a red carnation. This produces a pink carnation. What is the hybrid trait?

  35. PINK because… Red + White = Pink

  36. An orange goblin is crossed with a yellow goblin. What are the chances that they will have a red goblin baby?

  37. 0% If an orange goblin (RY) is crossed with a yellow goblin (YY), they will have 50% orange babies and 50% yellow babies.

  38. Two green hungry hippos are crossed. What are the chances they will have a yellow baby? What is the hybrid trait?

  39. There is a 25% chance that there will be a yellow baby hippo. The hybrid trait is green.

  40. A polka dotted white and maroon bonker is crossed with a maroon bonker. A) which pattern of heredity is this? B) What will their offspring be (in percentages)? C) What is the hybrid trait?

  41. This is codominance, there will be 50% maroon babies and 50% white and maroon polka dotted babies. The hybrid trait is white and maroon polka dotted.

  42. A genetic disorder that causes a defect in blood clotting.

  43. Hemophilia

  44. Why can there never be male calico cats?

  45. Because males only have 1 X chromosome!

  46. A colorblind man and a woman who is is homozygous and has normal vision is crossed. What percentage of their daughters will be carriers?

  47. 100% of their daughters will be carriers. Why? Because they each inherited an X chromosome from Dad.

  48. Determine whether or not sex-linked genes are usually recessive or dominant. Determine which sex sex-linked traits often occur in, and explain why.

  49. Sex linked genes are mostly recessive. They affect mostly males, because males have one X chromosome and must express the trait if they have inherited it.

  50. Come to the board and draw a pedigree for the following passage about freckles: Linda, Tony and Maria all have freckles. Their father, Gerald, does not, but his sister, Grace does. Their father Robert does not have freckles, but their mother, Nina, does. Grace’s husband, Ryan does not have freckles, but their son, Ryan Jr. does. Is this autosomal or sex linked? Dominant or recessive?
