 The table you sit at is your team  I will put a question up on the board  First group who has the correct answer will receive the point  The group with the most points at the end will receive a fabulous prize!

 What is the complete genetic material contained in an individual?

 Genome

 What is a threadlike structure of a nucleic acids and protein found in the nucleus of most living cells?

 DNA

 What is a genotype of an individual with two different alleles for a given trait?

 Heterozygous

 What are the possible genotypes for straight hair  Straight(S) hair is dominant to curly(s)

 SS  Ss

 All chromosomes except the sex chromosomes are called

 Autosomes

 Occurs when the phenotype of the offspring is in between the phenotypes of the two parnets

 Incomplete Dominance

 A trait that is carried on the sex chromosomes is called?

 Sex – link trait

 What is a segment of DNA that codes proteins?

 Gene

 What shape is DNA in?

 Twisted Ladder  Double Helix

 Where in the cell are all the chromosomes located?

 Nucleus

 What are the four bases that make up the rungs of the DNA Ladder?

 Thymine  Adenine  Guanine  Cytosine

 Who was the founder of genetics?

 Gregor Mendel

How did Mendel discover genetics?

 Crossing pea plants and looking at different traits from the cross

 What are some of the traits Mendel looked at?

 Flower color  Seed color  Seed shape  Pod shape  Pod color  Flower position  Stem height

 What is a breeding experiment that tracks the inheritance of two traits?

 Dihybrid cross

 What is a way to determine traits that are passed on?

 Punnett square

 What are the possible genotype(s) for this cross? R R rr R = red eyes r = white eyes

 Rr

 What are the possible phenotype(s) for this cross? R R rr R = red eyes r = white eyes

 Red eyes

 What are the possible genotypes for the offspring? RRYY RRYy RrYY RrYy RRYy RRyy RrYy Rryy RrYY RrYy rrYY rrYy RrYy Rryy rrYy rryy RYRyrYryRY Ry rY ry

 RRYY  RRYy  RrYY  RrYy  Rryy  rrYy  rryy

 If this punnett square shows incomplete dominance, what are the possible phenotypes? R r Rr R = Red flower r = white flower

 Red  Pink  White

 Explain co-dominance

 When the heterozygous offspring show both phenotypes

 Explain the difference between genotype and phenotype

 Phenotype = visible trait determined by the genotype  Genotype = the genetic make up of an organism

 When two alleles in a gene pair are different, then one allele can control the expression of the trait and the other can be hidden is called?

 Law of Dominance

 An individual who has the allele for a trait or disease but does not have the disease or outwardly express the trait is called?

 Carrier

 Reproductive Cell

 Gamete

 Any characteristic that can be passed be inherited from parent to offspring

 Trait

 What is a pedigree?

 A diagram of the genetic history of an individual
