Essential Questions: Reflect on the Essential Questions before you dive in…

1. If you were quizzed today, which questions would you know the answers to already? Type the number of the question(s) below.
2. Which questions would you need to learn more about to answer confidently? Type the number of the question(s) below.
   1. What are inherited traits?
   2. How are traits governed by the genetic material found in the genes within chromosomes in the cell nucleus? may very may very

Inherited Traits

• (^) Known as the “father of modern genetics”
• (^) Born in 1822
• (^) A monk in Austria, Mendel discovered the basic principles of heredity through experiments with pea plants

Gregor

Mendel

Think About It

Think about Gregor Mendel growing generation upon generation of pea plants, trying to find out why some plants produced certain traits while others didn’t. Think about how hard it can be just to keep plants alive! If you were like Mendel and trying to design experiments with pea plants, what would you need to think about in your planning in order to get good results? using the same types of pea plants.

Inherited Traits

• (^) Traits that hide other traits when passed on to offspring
• (^) Shows its specific trait, even if only one parent passed the gene to the offspring
• When a calf inherits dominant white face gene from the bull, the calf will have a white face

Dominant Traits

Quick Action: INB

Inherited Traits

Study the dog family picture below and answer the reflection questions. What dominant traits do you see in this family? What traits do you think could be recessive? size, face shape, ear shape, black color fur, type of fur light brown fur

Think About It

Imagine two very large lions have a cub. It is likely that the cub would have genes for being large, too. What are some environmental factors that might result in the cub not growing to its full potential? for food and water sources.

Inherited Traits

• (^) When organisms reproduce, traits are passed from parent to offspring
• (^) It all begins in the organism’s cells
• (^) Cells are the basic building blocks of all living things
• (^) Cells contain the body’s hereditary material and can make copies of themselves

How are traits passed?

Where in our bodies is our hereditary material stored? nucleus and cells, in the dna.

Inherited Traits

• (^) Thread-like structures found in the nucleus of a cell that contains all DNA
• (^) Each chromosome is made of protein and a single molecule of DNA
• (^) Come in matching sets of two
• (^) Human cell nucleus contains 46 chromosomes, or 23 pairs
• (^) Half of these chromosomes come from one parent, and half come from the other parent

Chromosomes

Inherited Traits

• (^) Molecule that carries the genetic instructions for all living organisms
• (^) Short for deoxyribonucleic acid
• (^) Contains the specific instructions that make each type of living creature unique
• (^) Determines how the cells in a body will function

DNA

Quick Action: INB

Inherited Traits

Compare and Contrast Use the provided textboxes^ DNA^ Genes to create a Venn diagram that compares the similarities and differences between DNA and genes. Think about things like:

• (^) their relative size
• (^) what they code for
• (^) how many copies
• (^) and anything else you find helpful longer than a gene has instructions to make you unique short section of dna tells cells what traits show found in nucleus affect your traits

Inherited Traits

__________ contain(s) the nucleus. __________ contain(s) the chromosomes. __________ contain(s) the DNA. __________ contain(s) the gene. Drag the words at the bottom to the slide to their correct description below. (Hint: You will have one word left over.) Cell Nucleus Chromosomes DNA Gene

Inherited Traits

• (^) Physical characteristic of an organism
• (^) Not passed down to offspring genetically
• (^) Is a learned trait
• (^) Is a product of the environment’s influence on the organism

Acquired Traits

List examples of acquired traits you have learned over the years. how to ski, how to play soccer, and how to make friends

Think About It

Acquired traits can help an organism survive, even when its genes might suggest it wouldn’t do well. Think about how each organism might learn behaviors that would help it thrive: The runt of a litter of puppies might not be able to fight its siblings for food, but it might learn to… A kitten might have genes for poor vision, but it could learn to… hunt for food, steal food, beg for food have great smell, can run very fast, hear very well
