Genetics and Inheritance: Key Concepts
and Patterns Exam Questions and
Answers Graded A+
Genetics - Correct answer-the study of heredity
Heredity - Correct answer-transmission of traits from one generation to the next
Phenotype - Correct answer-physical appearance
Genotype - Correct answer-genetic makeup
P Generation - Correct answer-parental generation
F1 Generation - Correct answer-hybrid offspring of the parental generation
F2 Generation - Correct answer-offspring of a cross between two F1 plants
Alleles - Correct answer-Variations of a gene. Everyone has two alleles for every
gene.
Dominant allele - Correct answer-Allele that determines the organism's
appearance. Usually denoted by a capital letter (R)

, Recessive allele - Correct answer-has no noticeable effect on an organism's
appearance. Usually denoted by a lowercase letter (r).
Wild Type - Correct answer-typical form of traits that are found most often in
nature. Not always dominant.
Homozygous - Correct answer-Organism has the same alleles for a single gene
(RR- homozygous dominant, rr- homozygous recessive)
Heterozygous - Correct answer-Organism has different alleles for a single gene
(Rr).
Homologous Chromosomes - Correct answer-genes will be at the same location
(locus) on both.
Mendelian Genetics - Correct answer-Studied inheritance patterns in pea plants. He
first recognized there are certain traits and they pass to descendants.
Punnett squares - Correct answer-used to predict the genotypes and phenotypes of
offspring
Law of segregation - Correct answer-During gamete formation, the alleles of each
gene segregate from each other so that each gamete carries only one allele for each
gene.
