What is pedigree analysis? - ANSWER- a family tree that describes the
interrelationships of parents and children across generations
What is complementation? - ANSWER- the phenomenon by which the effects of
two different nonallelic mutations in a gene are partly or entirely canceled out
when they occur together
What does the result of a complementation cross tell you about the genetic basis of
some mutant phenotype in two individuals? - ANSWER- If complementation
occurs, this suggests that the mutations were on different genes; If during a
complementation cross the F1 progeny is all wild-type, complementation is
occuring
What phenotypic ratio is associated with gene interactions? - ANSWER- If the
genes are linked, we anticipate a 9:3:3:1 phenotypic ratio
,What phenotypic ratio is associated with recessive epistasis? - ANSWER- 9:3:4
What phenotypic ratio is associated with dominant epistasis? - ANSWER- 12:3:1
What phenotypic ratio is associated with duplicate recessive epistasis? -
ANSWER- 9:7
What phenotypic ratio is associated with duplicate dominant epistasis? -
ANSWER- 15:1
What does it mean for a gene to be epistatic? - ANSWER- The gene is expressed,
but masks the expression of another
What does it mean for a gene to be hypostatic? - ANSWER- The gene is masked
by another gene that is being expressed
Nucleoside vs Nucleotide - ANSWER- nucleoside: pentose sugar + nitrogenous
base
nucleotide: pentose sugar + nitrogenous base + phosphate group
What type of bonds bind nucleotide chains? - ANSWER- Phosphodiester bonds
, What are the 4 requirements for a molecule to be genetic material? - ANSWER- 1.)
Must contain important info to encode hereditary traits
2.) Must be capable of replication
3.) Must be capable of variation by mutation
4.) Must be able to express information
Where are chromosomes located? - ANSWER- cell's nucleus
what is a centrosome? - ANSWER- location in the cell that contains centrioles
What are centrioles? - ANSWER- microtubules that produce mitotic spindle fibers,
aids in cell division, and make up the cytoskeleton of the cell
How many centrioles are there for every centrosome? - ANSWER- 2 centrioles/1
centrosome
How many copies of each type of chromosome does each eukaryotic cell typically
have? - ANSWER- 2 copies
what are homologous chromosomes? - ANSWER- copies of the same type of DNA
