Mendel worked with plants; earlier studies used animals
Mendel was able to explain the blending hypothesis
Mendel's work was more quantitive
Mendel worked with wild species, not domesticated ones
Mendel found that offspring inherit characteristics from both parents
A or b
1:1 phenotypic ratio
3:1 genpotypic ratio
1:2:1 phenotypic ratio
3:1 phenotypic ratio
1:1 genotypic ratio
How new characteristics originated
Whether different characteristics were inherited together or separately
How plants and animals adapt to their environments
Whether the characteristics influence each other--whether color affects degree of roundness, for example.
Actually, Mendel never had a clear purpose in mind
Next to each other on the same chromosome
At corresponding locations on homologous chromosomes
On the X and Y chromosomes
Some distance apart on the same chromosome
At different locations on homologous chromosomes
They tend to be inherited together
They tend to violate Mendel's principle of independent assortment
They are on the same chromosome
They can form new combinations via crossing over
They are relatively rare; most genes are unlinked.
Coloring chromosomes with dyes and observing them under a microscope
Scrambling the chromosomes and observing how the flies changed
Crossing various flies and looking at the proportions of offspring
Transplanting chromosomes from one fly to another
Looking at crosses that showed independent assortment
All of the above
Keep careful records of the parent mice
Mate it with a brown mouse
Mate it with a mouse of its own genotype
Mate it with a white mouse
It can't be done
Impossible to tell given this evidence
In fruit flies, the genes for scarlet eyes and hairy body are located on the same chromosome.
Matings between earless sheep and long-eared sheep always result in short-eared offspring.
Wheat kernels can range from white to red in color, a trait controlled by several genes.
The human cystic fibrosis gene causes many symptoms, from respiratory distress to digestive problems.
An individual with both IA and IB alleles has blood group AB.
Sex-linked and dominant.
Not sex-linked and dominant.
Sex-linked and recessive.
Not sex-linked and recessive.
Impossible to say on the basis of this information.
Sex-linked traits are never seen in girls
The allele is carried on the Y chromosome.
Nondisjunction occurs in males but not in females.
Males carrying the alleles don't live long enough to be fathers.
A sex-linked allele cannot be passed from mother to daughter.
Knowing how the allele causes phenotypic effects
Being able to identify carriers
A test that can determine whether a fetus suffers from a disorder
Knowing which chromosome bears the allele that causes the disorder
Tracing the trait back through parents and grandparents
On the X and Y chromosomes
On homologous chromosomes
Both present in each of Edward's sperm cells
On the same chromosome but far apart
How common the allele is, relative to other alleles
Whether it is inherited from the mother or the father
Which chromosome it is on
Whether it or another allele determines the phenotype when both are present
Whether or not it is linked to other genes
Autosomal and dominant
Autosomal and recessive
Sex-linked and dominant
Sex-linked and recessive
Impossible to determine without further information
Whether genes for the two characteristics are inherited together or separately
How many genes are responsible for determining a characteristic
Whether genes are on chromosomes
The distance between genes on a chromosome
How many different genes a pea plant has
A or B only
AB or O
A, B, or O
A, B, AB, or O
