The Study of Genetics: The Basics
Go to the following website to complete the following questions. Use the interactive at the bottom.
Make sure you answer each question in detail, since we will be using this information to continue our
study of genetics. If you cannot find the information on the website, you may search the internet.

1. Genes are located somewhere in your body. How would we get to your genes? In chromosomes
which are in the nucleus to go and into the cells by the nucleus. Sections of DNA
2. Genes determine our inherited traits. What is a gene? A gene is a segment of DNA that involves
producing it shows what you will be like. Physical traits.
3. We inherit our genes from someone. Who do you get your genes from? You get your genes from
your parents.
4. Heredity explains a lot about who we are. What is heredity? It is a biological process that is
passed down to generations from genetics and inherence from your parents on offspring.
5. Traits are passed on from parent to offspring. What are traits? Give three examples. Eye color,
skin color, your height, diseases, and natural hair color.
6. How are traits passed on? How many genes for a trait do we get from each parent? Each parent
gives off half of their DNA to their children.
7. Some traits are dominant and some traits are recessive. What does this mean? How are they
represented? Which are more likely to show in an organism? Give an example of three
dominant traits and three recessive traits in humans. A dominant trait is a trait that will be
shown by an organism, no matter what complementary trait it is coupled with. Examples are
brown eyes or dark hair in humans. Cowboy Tongue. They are characteristics of yourself
between a person or thing. Perspective, Shoe size
A recessive trait is a trait that will be suppressed by a dominant trait, but will show when it is
coupled with a recessive trait. Examples are blue eyes and blood type O in humans. Dimples
8. Traits can be show as phenotypes and genotypes. What is the difference between these two?
Give an example of a phenotypes and its genotype. A genotype refers to the actual set of genes
that an organism carries inside. A phenotype is what the organism looks like (how the genes are
expressed). So for genotypes, you could have the combinations of RR, Rr, or rr.
But for phenotypes, the RR and Rr would both have red flowers and only the rr would have
white ones. Instructions for the trait.
9. When we get genes from our parents we can get several different combinations: one dominant
from our mom and one dominant from our dad. One recessive from our mom and one recessive
from our dad. One dominant from one parent and one recessive from the other parent. What is
it called when we get two dominant traits? two recessive traits? one dominant and one
recessive? Homozygous Dominant Homozygous Recessive Traits for both and if you have one
dominant and one recessive Heterozygous
10.
Who made the discovery about inherited traits? What organism did he use to do this?
Greg Mondel he was the Father of Gentics because he was the first one to understand how DNA
worked. He study pea plants.
