1. Who was Gregor Mendel? What did he study?

A priest at a Central Monastery who studied pea plants. He is considered the father of genetics.

2. What is heredity?

The passing of physical characteristics from parent to offspring.

3. What are the differences between purebred and a hybrid?

A purebred has the same alleles dominant and recessive/ traits (RR or rr), whilst the hybrid has different alleles/traits (Rr).

4. What are traits?

A characteristic that an organism can pass on through its genes.

5. What is a Punnett Square?

A chart that shows all the possible combinations of alleles that can result from a genetic cross.

6. What is a Punnett Square used for?

It can tell you the probability of your child having a trait.

7. What is the difference between genotype and phenotype?

The phenotype is an organism's physical appearance, and the genotype is the genetic makeup.

8. Example of a phenotype

black hair

9. Example of a genotype

Ss

10. What are chromosomes made out of?

chromatin

11. Genes are made of this

DNA

12. What is the result of meiosis?

The result is the resulting sex cells only have half as many chromosomes. This is how a unique being is created.

13. How can two organisms have the same phenotype but different genotypes?

You can have a situation where you have dominant alleles. You can look alike like twins, but not be the same. A person can be tall (dominant) and have the genotypes TT or Tt.

14. What is the difference between haploid and diploid cells?

2 Haploids make diploids; A haploid has one set of chromosomes and a diploid has two complete sets of chromosomes.
