Gene 3000 - Exam 1 Questions With Complete Solutions
3 steps of Amphimixis Correct Answers 1. recombination
2. gamete production : haploid gametes production by diploid
individuals via reductive meiotic division
3. Gamete Fusion : gametic exchange between individuals in
which haploid gametes fuse to produce a diploid offspring
Adenine goes with Correct Answers Thymine
After the first round of hardy weinburg, what happens? Correct
Answers the genotypic frequencies will be in the proportions of
p^2. 2 pq, q^2
Alleles are Correct Answers different versions of the same
gene
allelic frequency equations Correct Answers p = P + 0.5H
(frequency of A1 allele)
q=Q+0.5H (frequency of A2 allele)
p+q=1
amphimixis Correct Answers alternating phases of meiosis and
gamete fusion
Anaphase 2 (Meiosis) Correct Answers Chromatids separate
and move to the poles of the cell.
,Anaphase I (Meiosis) Correct Answers separation of
homologous chromosomes (sister chromatids)
N-2
C-4
apomixis Correct Answers unfertilized gametes produced by
mitosis like division producing daughter cells with unreduced #
of chromosomes
Are hetero or homogamatics at a disadvantage Correct Answers
hetero
Are species reproductively isolated?? Correct Answers NOO
artificial selection Correct Answers Breeding organisms with
specific traits in order to produce offspring with identical traits.
asexual reproduction Correct Answers A reproductive process
that involves only one parent and produces offspring that are
identical to the parent.
Asexual Taxa Correct Answers short lived
Automixis Correct Answers production of haploid gametes via
meiosis, but diploidy is usually restored by the fusion of haploid
nuclei from the same meiosis
Biometricians Correct Answers evolution via slow natural
selection
, Cats and Dogs: How did they domesticate? Correct Answers
One single domestication that spread geographically and then
genes were exchanged with local wildlife
Cell life cycle (stages) Correct Answers Interphase
(nondividing state)
1. DNA replication
2. Mitosis
3. Cytokinesis
changes in ploidy Correct Answers usually fatal except in
plants
Chi-square test Correct Answers Tells if it is significant ;
compare to the degrees of freedom
chromosomal fission/fusion Correct Answers fission : breaks
apart
fusion: comes together
chromosome structure Correct Answers
Citrus: Domestication pattern Correct Answers hybridized in
wild, then domesticated
Codons Correct Answers A three-nucleotide sequence of DNA
or mRNA that specifies a particular amino acid or termination
signal; the basic unit of the genetic code.
common ancestry (common ancestor) Correct Answers
produces groups within group that cluster based on similarity
