The Father of Genetics, , discovered that traits are passed down from to . He used plants because they reproduce quickly and asexually and have obvious traits.
In cocker spaniels, the allele for black coats (B) is dominant over the allele for brown coats (b). If a brown cocker spaniel is crossed with a heterozygous black cocker spaniel, what are the alleles of both parents?
In cocker spaniels, the allele for black coats (B) is dominant over the allele for brown coats (b). If a brown cocker spaniel is crossed with a heterozygous black cocker spaniel, what percentage of puppies can be expected to have black fur?
A man and a woman both have freckles, which is a dominant trait. They have two children- one has freckles and one does not. What are the alleles of the parents?
A man and a woman both have freckles, which is a dominant trait. They have two children- one has freckles and one does not. What is the probability they have a child with no freckles?

What are the chances of getting offspring that are heterozygous for smooth and yellow peas (SsYy)?
What are the chances of getting offspring that are wrinkled and green (yy and ss)?
What is the ratio among the following phenotypes below:
Round Yellow (Dominant Dominant)
Round Green (Dominant Recessive)
Smooth Yellow (Recessive Dominant)
Smooth Green (Recessive Recessive)
Match the description with the type of dominance.
Heterozygous shows both traits side by side
Both traits are equally dominant
Neither trait is dominant
With chicken and black chicken make a black and white speckled chicken
Heterozygous is a blend of the two homozygous traits

In horses, the allele for a bay coat and the allele for a cream coat can combine to make a buckskin coat (brown with black mane, tail, and legs). The allele BB is used for bay; CC is used for cream. Buckskin horses have one bay and one cream allele BC. The genotype BC makes a buckskin coat, as both alleles are dominant.
This inheritance pattern is called
In horses, the allele for a bay coat and the allele for a cream coat can combine to make a buckskin coat (brown with black mane, tail, and legs). The allele BB is used for bay; CC is used for cream. Buckskin horses have one bay and one cream allele BC.
Cross a bay stallion with a buckskin mare on scratch paper. Match the phenotype with the correct percentage for offspring.
In humans, there are four blood types: A, B, AB and O. The blood type is dependent on the type of antigen present on red blood cells (A, B, or both). Individuals that lack the antigens are type O. This is the recessive trait. A and B are both equally dominant and both antigens can be expressed, which results in AB blood type. This is an example of
The allele for red is R and the allele for white is W. In snapdragons, flower color is controlled by , where the heterozygous offspring are pink.
Hair color in certain breeds of horses can be Brown (B), White (W) or Palomino (a tan color resulting from the heterozygous genotype BW which shows incomplete dominance). Complete a cross between two palomino horses on scratch paper. What percentage of offspring would be white?
If a man who has heterozygous type A blood and a woman with type AB blood have offspring, what are the chances that they will have a baby with type O blood?

What type of mutation is shown, when comparing this mutated chromosome with the original?
No genetic variation

Disadvantage of Cloning
Farmer Brown grows corn for a living. His corn production has steadily declined over the past decade. One day, Farmer Green suggests to Farmer Brown that he should clone his highest-yielding corn plant in order to produce more ears of corn per plant next year. Farmer Brown is not sure about Farmer Green's idea as he has heard both positive and negative outcomes about cloning. Why might Farmer Brown be hesitant to clone his corn?
Nondisjunction occurred to cause an unequal division of chromosomes in the gametes. Here is a kayotype with a disorder. Where is this disorder located?
