Who is Gregory Mendel?
Who is the father of genetics?
|
What is a phenotype?
What are physical characteristics called?
|
What are Purple flowers?
Purple flowers are dominant to white.
What is the phenotype for the genotype PP? |
What is heterozygous? or What is Short hair?
In cats, long hair is recessive to short hair. A true-breeding (homozygous) short-haired male is mated to a long-haired female. What will their kittens look like?
|
What is Ss?
In guinea pigs, the allele for short hair (S) is dominant.
What genotype would a heterozygous short haired guinea pig have? |
What is a pea plant?
What type of plant was initially used to study genetics?
|
What is a null hypothesis?
the hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
|
What is incomplete dominance?
Suppose a white-furred rabbit breeds with a black-furred rabbit and all of their offspring have a phenotype of gray fur. What does the gene for fur color in rabbits appear to be an example of?
|
What is an autosomal dominant trait?
A pedigree with a pattern of affected offspring with affected parents shows the inheritance of
|
What is 100%?
A TT (tall) plant is crossed with a tt (short plant).
What percentage of the offspring will be tall? |
What is a recessive trait?
What is a trait that ONLY appears when it it has a homozygous genotype?
|
What are alleles?
What represents the genotype?
|
What is red?
In snapdragons, flower color is controlled by incomplete dominance. The two alleles are red (R)and white (r). The heterozygous genotype is expressed as pink.a.What is the phenotype of a plant with the genotype RR?
|
What is autosomal recessive trait?
A pedigree with a pattern of affected offspring with unaffected parents shows the inheritance of:
|
What is 25%?
A Tt plant is crossed with a Tt plant. Tall is dominant to short. What percentage of the offspring will be short?
|
Who is Reginald C. Punnet?
Who invented the punnet square? (first and last name)
|
What is co-dominance?
What type of inheritance causes spotting in fur color?
|
What is co-dominance?
A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?
|
What is a 50% chance?
If two people who are both carriers for a genetically inherited fatal recessive disease decide to become parents, what will be the odds that their children will also be carriers?
|
What is sex-linked recessive?
What type of trait is shown on a pedigree that shows mainly males affected and may skip a generation?
|
What is Mendel's Law of Segregation?
___________ says that organisms have two copies of every gene and that they get one copy of each gene from each parent
|
What is incomplete dominance?
A type of inheritance where there is a blending of two phenotypes is called…
|
What is a 9:3:3:1 ratio?
In a dihybrid cross between two different unlinked traits and the parents are both heterozygous for both traits, you should get what ratio?
|
What is a 0% chance?
If two parents are homozygous for a genetically inherited recessive trait, what is the probability that they will have a child who does not have this trait in his or her phenotype?
|
What is autosomal recessive?
What type of trait is shown on a pedigree that shows offspring affected with a trait that come from parents that are not affected with a trait?
|
