2.  These are sections of chromosomes that code for a trait.  A gene

3.  This is a characteristic that can be passed from parent to offspring.  Trait

4.  What would device would you use to predict the possible offspring of a cross between different genotypes?  A punnett square

5.  What is genetics?  The passing of traits from one parent to its offspring

6.  How could you determine a person’s phenotype?  By looking at the person

7.  The genetic make-up of an organism is called what?  Genotype

8.  This type of allele in not fully expressed when paired with a dominant allele.  A recessive.

9.  What do you call two alleles in a gene pair that are identical?  Homozygous

10.  If you crossed a heterozygous individual with a homozygous recessive individual, what would the genotypes of their children look like?  Half would be heterozygous and half would be homozygous recessive

11.  What do you call an organism that receives different forms of a genetic trait from each parent?  Hybrid or heterozygous

12.  If you flip a coin, this is the probability you’ll get tails? ½½

13.  What are haploid cells?  Cells that contain half the amount of chromosomes

14.  What phase of meiosis is this?   Anaphase II

15.  What phase of meiosis is this?  Prophase I

16.  What phase of meiosis is this?  Telophase II

17.  What phase of meiosis is this?  Metaphase II

18.  What is a pedigree?  A graph that shows how traits are passed from generation to generation.

19.  Does this statement occur in meiosis or mitosis: two cells are produced at the end.  Mitosis

20.  Does this statement occur in meiosis or mitosis: the result is identical cells.  Mitosis

21.  Does this statement occur in meiosis or mitosis: results in cells that have half the amount of chromosomes.  Meiosis

22.  What are sperm cells and egg cells called?  Gametes

23.  What do you call a cross made to study a single trait?  Monohybrid cross

24.  Draw a punnett square for the following cross: A heterozygous individual for straight hair is crossed with a heterozygous individual for straight hair. Straight hair is dominant to curly hair. Use an “S” for the dominant trait. SS S s s S Ss ss
