Gregor Mendel used pea plants to study
the inheritance of traits
offspring that result from crosses between parents with different traits
hybrids
the chemical factors that determine traits are called
alleles
the principle of dominance and recessiveness states that
some alleles are dominant
some are recessive
if a pea plant has a recessive allele for green peas, it will produce
green if it does not also have a dominant allele for yellow peas
In the P generation, a tall plant was crossed with a short plant. short plants reappeared in the F2 generation because
the allele for shortness and the allele for tallness segregated when the F1 plants produced gametes
organisms that have two identical alleles for a particular gene are said to be
homozygous
a Punnett Square shows all of the following except
the actual results of a genetic cross
If a pea plant that is heterozygous for round, yellow, peas. (RrYy) is corssed with a pea plant that is homozygous for round peas but heterozygous for yellow peas (RRYy), how many different phenotypes are their offspring expected to show?
2
A male and female bison that are both heterozyous for normal skin pigmentation (Aa) produce an albino offspring (aa). Which of Mendel's principles explain(s) why the offspring is albino?
dominance & recessive and segregation
Mendel never became a teacher because he had terrible text anxiety and ironically failed the _________ portion of the exam.
science
how many different alleles combinations would be found in the gametes produced by a pea plant whose genotype was RrYY
2
how many alleles do gametes have for each gene
one
what is the process that gametes are produced by
meiosis
The genotype of an individual that shows the domiant phenotype can be determined by crossing it with an individual that is
homozygous recessive
when 2 pea plants that are heterzygous for yellow peas are crossed the resulting offspring have a genotypic ratio of
1:2:1
an egg cell in a plant is fertilized by pollen from the same plant in
self-pollination
if a family has 3 daughters, the probability that the next child will be a
1/2
if a short hair (L) is dominant to long hair (l) animals LL and Ll hav ethe same
phenotypes
short hair (L) is dominant to long (l). If a short-haired animal of unknown origin is crossed with a long-haired animal and they produce one long-haired and one short-haired offspring, this would indicate

what is this test known as
the short haired animal was not pure-breeding

test cross
what is aaBB
homozygous
the F2 phenotypic ratio of a monohybrid cross is
3:1
Blood O can donate to all other blood types because
0 is recessive and does not have glycoprotein
Type A blood contains ___ antibodies
B
Mendel tested the pea plants in the F1 generation for ___ years to make sure they were _______
2
homozygous
if an individual that is blood type AB has a child with an individual that has blood type B then what are the possible blood types of the child
A, B, AB
what does it mean to be Rh(-)
no RH protein
Blood type AB can get blood from
anyone
a family has 4 children, one with blood type A, one with type B, one with type AB and one with Blood O

what are the genotypes of the parents
IAi
IBi
a parent with blood type A+ is married to an AB- person

a) could this couple produce a baby with blood type o+ ?
b) AB -
c)B+
a) no
b) no
c) yes
if the blood type of a child is A and the blood type of a mother is B what can't be the blood type of the father?
O, B
the position of a chromosome on a gene is a _______
locus
