TEST WEDNESDAY
The passing of traits from parent to offspring is called _____________________________.
The study of heredity is called ____________________________________________
The father of genetics was ____________________________________________
THE LAW OF ___________________ two alleles for a trait separate when gametes are formed.
The physical appearance of an organism( expressed traits) ______________________________
Genotype in which the alleles for a traits are the same is (hh OR HH) _____________________
Genotype in which the alleles for a traits are different (Hh) ___________________________
The law of ____________________________________ states that the inheritance of one trait had
no effect on the inheritance of another. (hair color does not determine eye color)
Be able to read and set up punnett squares for monohybrid, dihybrid, sex-linked traits, blood type.
A diagram that shows the inheritance of a trait across several generations of a family is called a
_______________________.
Be able to interpret pedigrees. (males, females, parents, children, carrier, homozygous,
heterozygous)
An inheritance pattern in which the alleles for a trait are attached to the X or Y chromosomes is
called ______________________________. (Hemophilia, colorblindness)
An example of inheritance pattern in which there are more than two alleles for the trait (multiple
allelic) is ____________________________.
A ___________________ is a person who is heterozygous for a recessive trait.
A CHILD HAS BEEN BORN WITH A GENETIC DISORDER THAT NEITHER OF THE PARENTS
HAVE. HOW IS THIS POSSIBLE?
How is hemophilia carried and inherited in females and males? Be able to identify/explain how a
son or daughter would inherit the disorder. Show the genotypes and phenotypes of females and
males.
In X-linked inheritance it is not possible for a color blind father to pass the trait to his ________.
A color blind _____________ will pass the trait her her son.
Why can’t a person have ABO blood type?
Show the genotypes of a person with A blood type. B Blood type? O blood type?
When a red flowering plant is crossed with a white flowering plant it produces pink flowers. What
type of inheritance pattern is this?______________________
In fruit flies eye color is a sex-linked trait. A female fruit fly heterozygous for red eyes is crossed
with a male fruit fly with white eyes. What percent of the offspring will have red eyes?
In cattle when a red cow is mated with a white bull the offspring are roan. What is the name of this
inheritance pattern?
When roan cattle are mated, what are the genotypes and phenotypes of the offspring.
What is the difference between a monohybrid and a dihybrid cross?
