Genetics- 7th Grade
Who was Gregor Mendel? What did he study? - correct answer-A priest at a Central
Monastery who studied pea plants. He is considered the father of genetics.
What is heredity? - correct answer-The passing of physical characteristics from parent to
offspring.
What are the differences between purebred and a hybrid? - correct answer-A purebred has
the same alleles dominant and recessive/ traits (RR or rr), whilst the hybrid has different
alleles/traits (Rr).
What are traits? - correct answer-A characteristic that an organism can pass on through its
genes.
What is a Punnett Square? - correct answer-A chart that shows all the possible combinations
of alleles that can result from a genetic cross.
What is a Punnett Square used for? - correct answer-It can tell you the probability of your
child having a trait.
What is the difference between genotype and phenotype? - correct answer-The phenotype is
an organism's physical appearance, and the genotype is the genetic makeup.
Example of a phenotype - correct answer-black hair or eye color
Example of a genotype - correct answer-Ss
Heterozygous - correct answer-An organism that has two different alleles for a trait
Homozygous - correct answer-An organism that has two identical alleles for a trait
