gene ANSWER a segment of DNA that codes for a polypeptide [or an RNA chain]
the unit of heredity. A segment of DNA that carries information from one generation to
the next
what do alleles do and what are they? ANSWER change their frequency in populations
variations of genes
blending inheritance ANSWER held that traits of mother and father were mixed together
and forever altered in the offspring (like mixing paint)
couldn't explain brown cow and white cow making a brown cow or a two brown cows
making a white cow
key's to mendels success - ANSWER 1. chose a good study species
-makes plenty of data
-short generation time
-easy to arrange mating between species
2. he looked at discontinuous traits
3. studied true-breeding strains. matings within true-breeding strains always produce
offspring that resemble their parents
4. he studied one trait at a time
5. he counted offspring
continuous traits - ANSWER traits which vary across an unbroken range of values
discontinuous (discrete) traits - ANSWER traits which show two or more distinct or
, separate forms
hybrid - ANSWER offspring of genetically dissimilar parents
monohybrid - ANSWER hybrid between two strains that differ only at a single trait
dominance- ANSWER a condition in which one member of an allele pair is manifested to
the exclusion of the other. the manifested allele is dominant and the hidden allele is
recessive
mender's law of segregation- ANSWER 1. the two copies of a gene separate (segregate)
equally during gamete formation, so that half of the gametes carry one member of the
pair, and half carry the other member
2. During fertilization the gametes combine at random. That is, they come together
without regard as to which allele each one possesses
phenotype ANSWER the apparent characteristic of an organism
genotype ANSWER the allelic composition of an individual
Coat color in guinea pigs is determined by one gene with two alleles. One guinea pig
from a true-breeding black strain is crossed to a guinea pig from a true-breeding white
strain. All the F1 offspring are black. Two of the F1 offspring are mated to each other.
Which of the following is the expected proportion of white F2 offspring?
A) 1/4
B) 1/3 C) 1/2 D) 3/4 E) All - ANSWER 1/4
In guinea pigs coat color is determined by a single gene with two alleles. A guinea pig
from a true-breeding black strain is mated with a guinea pig from a true-breeding white
strain. The F1 progeny are all black. Two of the F1 progeny are mated with each other.
