It controls all the cell activities like:
Making new cells
Energy production
Getting rid of wastes

26. What is inside the Nucleus? :
Unit 3 Lesson 1 What Are Cells?
What is inside the Nucleus? :
Chromosomes are structures
in the cell’s nucleus
made of DNA.
DNA is made of
sections called genes.
Genes control an organism’s characteristics such as:
(Height , eye color, skin color, ability to roll your tongue)

29. Where Do Traits Come From?
Unit 3 Lesson 1 What Are Cells?
Where Do Traits Come From?
Inherited traits are characteristics passed from parents to their offspring.
Examples of these characteristics might include eye color, hair color, freckles, and face shape in humans, and fur color and texture in animals.

30. Why are there genetic differences
Unit 3 Lesson 1 What Are Cells?
Why are there genetic differences
Genetic differences are because an organism receives only half of its genes from each parent.
This results in genetic differences between parents and offspring.

31. Dominant and Recessive Traits :
Unit 3 Lesson 1 What Are Cells?
Dominant and Recessive Traits :
Mendel hypothesized that traits in organisms are controlled by a pair of factors and each parent passes on one factor.
Copyright © Houghton Mifflin Harcourt Publishing Company

32. A recessive trait appears only if the 2 factors are recessive.
Unit 3 Lesson 1 What Are Cells?
Strong traits that will appear are called : Dominant traits. (eg. Tallness)
Weak traits that will not appear are called : recessive traits. (eg. Shortness)
A recessive trait appears only if the 2 factors are recessive.
What happens if a child is having a tallness factor (dominant) and a shortness factor
( recessive)?
What happens if a child is having 2 shortness factors (recessive)?
