AP Biology Questions with CORRECT Answers
Question:
meiosis
Answer:
Cell division that produces reproductive cells in sexually reproducing organisms
Question:
haploid
Answer:
An organism or cell having only one complete set of chromosomes
Question:
diploid
Answer:
An organism or cell having two sets of chromosomes or twice the haploid number
Question:
crossing over
Answer:
the exchange of genes between homologous chromosomes, resulting in a mixture of
parental characteristics in offspring
Question:
Prophase 1
Answer:
Chromosomes become visible; nuclear envelope breaks down; crossing-over occurs
Question:
Independent assortment
Answer:
genes for different traits can segregate independently during the formation of gametes
, Question:
Anaphase 1
Answer:
homologous chromosomes separate and are pulled to opposite ends of the cell
Question:
Anaphase 2
Answer:
sister (individual) chromatids separate
Question:
gametes
Answer:
sex cells (made with meiosis)
Question:
centromere
Answer:
Area where the chromatids of a chromosome are attached (used to help count the
number of chromosomes)
Question:
nondisjunction
Answer:
Error in meiosis in which homologous chromosomes fail to separate = abnormal number
of chromosomes in daughter cells
Question:
Gregor Mendel
Answer:
"Father of Genetics"
Question:
recessive
Answer:
An allele that is masked when a dominant allele is present
