Read It! Station Directions

Each member of the group will read the passage and answer the questions from the task cards on the lab sheet in the Read It! section.

It is important to remember that the answers will come directly from the reading passage.

Inherited Traits

Everyone has traits: characteristics and qualities that make us who we are. We have physical traits, like brown hair, blue eyes, long legs, freckles and funny-looking toes. We also have personality, or character traits. Those include things like being great at telling jokes, compassion, intelligence, warmth, creativity.

Where do traits come from? Its easy to spot certain physical traits that were passed down genetically from parents to offspring. Traits like red hair and knobby knees are inherited.

Whats more complex, and, many would argue, more interesting, is to find the source of traits that could have formed from individual reactions to a certain environment. Many traits exist in a gray area between these two extremesinheritance and development.

One example is body type. This might seem like an easy one. People are genetically predisposed to their body type. But once diet becomes a factor, environment begins to play a major role in how the body develops. So body type is one example of a trait that is a combination of inheritance and interaction with an individuals environment.

So many of our most defining traits have been learned, rather than inherited. For instance, if youre really great at video games, its not because one or both of your parents passed down skills in some video game mastery gene. Its because you practiced, played a lot of video games, and developed those skills yourself.

Of course, there are ways our brains can form that are more advantageous to advanced video game playing. Say you were born with an extra-large, extra-powerful section of your brain that commands hand-eye coordination. Thats inherited. What you do with it, how you choose to develop that advantage, is up to you.

You can pierce your nose, get a tattoo, dye your hair, shave your head, get your kidneys removed, put on a silly hatit doesnt matter how much you alter your body during your lifetime. None of those things will translate into genetic material to be passed down to the next generation.

from one country

Genes are small portions of your DNA that are transferred from parents to offspring and help determine certain characteristics.


1.Read through each of the inherited traits and determine if you have a dominant gene or a recessive gene on your lab sheet.


Explore It! Station Directions

One member of the group will read the task cards in order.The group will be responsible for completing each of the tasks that are being read.

Each member of the group will then write their conclusions down on the lab sheet in the Explore It! section.


Look at the 4 cards with only 1 vocabulary word on them.

1.Try to organize them from smallest to largest and write the order on your lab sheet.

Now look at the 4 cards with the definitions on them.

1.Try to organize them from smallest to largest and write the order on your lab sheet.


Genes are small sections of the DNA which determine your traits and

characteristics. Many genes together make up your 23 pairs of chromosomes.

Chromosomes contain all of the DNA for the organism, and they are stored in the nucleus of nearly every cell in your body.

1. On your lab sheet write the correct order of each of the new vocabulary terms you learned starting with the smallest.


GenesChromosomes

DNA

Nucleus

Genes parts of the DNA which control the traits of an organism

DNA molecule that carries the genetic instructions for all living organisms.

Found in the chromosome.

Chromosomes Thread-like structures that are found in the nucleus of a cell that contains all DNA.

Nucleus stores the cells hereditary material or DNA

Illustrate It! Station Directions

Each member of the group will draw a quick sketch on the lab sheet the shows they understand the concept that is being taught.

Use the colored pencils and markers that are provided.

The directions for the sketch are provided on the task card at the table.


Illustrate It! Station Directions

Draw a quick sketch and come up with an acronym (Example: SCUBA Self Contained Underwater Breathing Apparatus)to help you remember the following information.

Genes are found in DNA, which are found in

Chromosomes, which are found in the Nucleus

of a cell.


Organize It! Station Directions

It is recommended that you have completed at least two

of the following stations before working at this station.

-Read It!
