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
|
