AP Biology Questions with CORRECT Answers
Question:
complete dominance
Answer:
the dominant all shows up in the offspring and the recessive allele gets covered up and
doesn't show
Question:
incomplete dominance
Answer:
some alleles don't completely dominate others, partially show by blending together how
they are expressed
Question:
codominance
Answer:
both alleles are completely expressed at the same time like spots or stripes
Question:
gamete
Answer:
sex cells
Question:
somatic cells
Answer:
body cells
Question:
zygote
Answer:
a fertilized egg
, Question:
describe meiosis in plants and animals, giving specific attention to the following:
a. the stages of meiosis
b. the function of meiotic daughter cells and the organs where meiosis takes place
c. the contributions to genetic variation
Answer:
Prophase 1-nuclear membrane breaks down, chromatin condenses into chromosomes,
MTOC's go to opposite poles, spindles develop
Question:
Synapsis-homologous chromosomes pair, crossing over between non-sister
chromatids=genetic material exchange, spindles connect to centromere and pull to
middle metaphase 1-chromosomes aligned anaphase 1-each member of the
homologous pair of chromosomes pulled to opposite poles telophase 1-nuclear
membrane appears cytokinesis and short interphase 1 may occur prophase 2-same as
prophase 1, but no synapsis metaphase 2chromosomes spread in the middle, no pairing
anaphase 2-chromosomes separated into 2 chromatids/chromosomes and pulled by
spindles to opposite poles telophase 2-meiosis concluded, cytokinesis separates nuclear
into 4 haploid cells reduction division in sexual reproduction. Daughter cells haploid.
Gametes--sex cells crossing over, metaphase 1 when homologous pairs randomly align,
zygote is combination of randomly selected egg and sperm epistasis
Answer:
occurs when a gene at one locus alters or influences the expression of a gene at a
second loci
Question:
chromosomes
Answer:
condensed chromatin, humans have 46 chromosomes
Question:
product of meiosis
Answer:
4 haploid cells that are not genetically identical
Question:

the dominant all shows up in the offspring and the recessive allele gets covered up and
doesn't show
