WHAT SHOULD I KNOW FOR THE TEST
Genetics
Test Date:
Who is considered to the be the “Father of Genetics?”
What was Gregor Mendel’s contribution to our understanding of genetics?
What is the relationship between the P, F1, and F2 generation?
When does segregation and independent assortment of alleles happen?
Explain the difference between and give examples of each:
Complete dominance
Incomplete dominance
Codominance
Explain the following:
Homozygous
Heterozygous
Dominant
Recessive
Purebred
Name:
Test Date:
Hybrid
Genotype
Phenotype
What is the difference between a monohybrid and dihybrid cross?
Be able to work complete dominance, incomplete dominance, codominance, sex
linked, multiple alleles, and dihyrbid Punnet squares. Be able to determine the
genotypic and phenotypic ratio of each type.
In carnations, red and white are homozygous, while pink occurs in heterozygotes.
Cross two pink carnations. What percent of the offspring should be white?
Cats may be orange, white, or tabby (orange and white). If a white cat is crossed
with a tabby cat, what percent of the offspring are expected to be white?
If hemophilia is a sex-linked recessive trait, and a carrier female marries a normal
male, what percent of their sons will be hemophiliacs?
Human blood types show multiple allelism. A and B are dominant and O is
recessive. Cross a heterozygous A female with a male that has type AB blood. Give
the genotypic ratio of the offspring.
