1. gene - Ans: a section of DNA on a chromosome that codes for a protein.
2. alleles - Ans: one version of a gene. You have one on a chromosome from Mom,
the other on the chromosome from Dad. They are represented by capital or lower
case letters.
3. dominant allele - Ans: A version of a gene where you only need one copy in
order to express that trait. Represented by a capital letter
4. recessive allele - Ans: A version of a gene that is not expressed if paired with a
different type of allele. Represented by a lowercase letter.
5. homozygous - Ans: two of the same alleles. If it is two upper case, the trait is
dominant, if it is two lower case, the trait is recessive; (RR/rr)
6. heterozygous - Ans: A genotype with two different alleles. One capital next to a
lower letter; the capital is dominant and is next to a recessive allele; (Rr)
7. complete dominance - Ans: the dominant allele will take over the appearance of
the recessive allele when there is an uppercase and a lower case together
8. homozygous recessive - Ans: Two copies of the recessive allele make up the
genotype. When there are two lower case letters together
9. homozygous dominant - Ans: Two copies of the dominant allele makes up the
genotype. There are two upper case letters.
10. genotype - Ans: The genetic makeup-- the alleles a person has.
11. phenotype - Ans: How the genotype is expressed in the individual.
12. Punnet Square - Ans: A tool that is used to determine the likelihood of offspring
traits.
13. Genotypic ratio - Ans: count the number of squares that have the same letter
combination
14. Phenotypic ratio - Ans: count the number of squares that have different physical
appearances
15. homozygous x homozygous - Ans: no ratio; 100% have the same genotype and
phenotype
