Bio 183 - Exam 4 2026 Questions And
Answers | A+ Graded | With Expert
Solutions
variations in a single DNA
building block occuring in
over 1% of a population.
these are used as
SNPs
markers/signposts where
the closer a SNP is to a
gene, the more likely
they're inherited together.
an investigative method used to identify genes
associated with an organism's specific traits
(phenotype). by searching the genomes of
GWAS (genome wide association study)
thousands of organisms, scientists find common
DNA variations directly linked to physical
differences.
causative SNP: directly changes protein
production; directly responsible for the trait
associated SNP: signals nearby disease genes;
what are the different types of SNPs? nearby or inside regulatory sequences, but more
likely inherited together due to proximity
unassociated SNP: no known effect; far from
gene, rarely inherited together
humans have 23 pairs of chromosomes,
what are the differences between dog and while dogs have 39.
human genomes? humans have around 2.8 billion bases,
while dogs have 2.4 billion.
pairs of matching chromosomes in diploid
organisms, with one inherited from each parent.
what are homologous chromosomes? they possess the same genes in the same order,
size, and location, but may have different
versions of those genes (different alleles).
, a pictorial representation of all the
karyotype chromosomes of a person, showing each
chromosomes pair.
meiosis this is the nuclear division that results in
genetically different cells than the mother cells.
there are two separate cell divisions that occur
