Mendelian Genetics : $500 Answer BACK TO GAME Genes are separate chromosomes assort into gametes independently

Non-Mendelian: $100 Question BACK TO GAME ANSWER Which blood type is the universal donor? Why?

Non-Mendelian : $100 Answer BACK TO GAME Type O, it does not have any antigens on the surface of the red blood cells (they will not react with the antibodies in the other blood types)

Non-Mendelian : $200 Question BACK TO GAME ANSWER Skin color, eye color, and height in humans are examples of these type of traits that cause a bell shaped curve set of phenotypes

Non-Mendelian : $200 Answer BACK TO GAME polygenic

Non-Mendelian : $300 Question BACK TO GAME ANSWER This type of inheritance exists when there exists a phenotype that is “intermediate” between those of the parents

Non-Mendelian : $300 Answer BACK TO GAME Incomplete dominance

Non-Mendelian : $400 Question BACK TO GAME ANSWER This type of inheritance takes place when you can see both phenotypes expressed when two different alleles are inherited

Non-Mendelian : $400 Answer BACK TO GAME Co-dominance

Non-Mendelian : $500 Question This type of inheritance will have ONLY female carriers BACK TO GAME ANSWER

Transcription : $500 Answer BACK TO GAME Sex-linked

Punnett Squares : $200 Question BACK TO GAME ANSWER A person with type A blood marries a person with type B blood. They have a child with type O blood. Create the Punnett square to show this inheritance. What is the chance of having a child with type O?

Punnett Squares : $200 Answer BACK TO GAME 25%

Punnett Squares : $300 Question BACK TO GAME ANSWER Brown hair (B) is dominant blonde hair (b) is recessive. Straight hair (S) is dominant and curly hair (s) is recessive. A man who is homozygous for brown, straight hair mates with a woman who is homozygous for blonde, curly hair. What is the chance they will have a child with brown, straight hair?

Punnett Squares : 500 BACK TO GAME ANSWER What is a test cross? What do the results of a test cross indicate?

Punnett Squares : 500 BACK TO GAME If you do not know the genotype of an individual with the dominant phenotype you can cross it with a homozygous recessive individual. All dominant phenotype in F1 = homozygous dominant 1:1 ratio of dominant phenotype to recessive phenotype
