AP Biology- Genetics Exam Questions
and Answers Graded A+
Character - Correct answer-an observable heritable feature.
Trait - Correct answer-any detectable variation in a genetic character.
True-breeding - Correct answer-Referring to plants that produce offspring of the
same variety when they self-pollinate.
Hybridization - Correct answer-carries two different alleles of the same gene
P generation - Correct answer-parental generation
F1 generation - Correct answer-first filial generation (the word filial from the Latin
word for "son"), the hybrid offspring of the P generation.
F2 generation - Correct answer-(second filial generation), offspring of the F1
hybrids' self-pollination.
Alleles - Correct answer-Alternate versions of a gene.

, Punnett Square - Correct answer-a diagram that helps you predict the allele
composition of offspring from a cross between individuals of known genetic
makeup.
Homozygous - Correct answer-an organism having a pair of identical alleles for a
character is said to be ___________ for the gene controlling that character.
Heterozygous - Correct answer-an organism that has two different alleles for a
gene is said to be ____________ for that gene.
Phenotype - Correct answer-an organism's traits.
Genotype - Correct answer-an organism's genetic makeup.
Law of Independent Assortment - Correct answer-Each pair of alleles segregates
independently of other pairs of alleles during gamete formation and combines
independently of each other.
Rules of Multiplication - Correct answer-To determine the probability of two or
more independent events, you multiply the probability of one event by the
probabilities of the other events.
Rules of Addition - Correct answer-If you add up the individual probabilities of
two or more mutually exclusive events, you can predict the probability for any one
of them to occur.
