Traits & DNA
Explain what it means to inherit traits.
To pass genes from parent to child.
Heredity is the passing on of traits. Parents pass on their DNA to their offspring, which codes for the specific traits that offspring possess.
(WORTH TRIPLE) Requires two parents that each share ___ of the genetic information.
Half, 23 Chromosomes each
Is the offspring identical (clone) or genetically different (unique)?
The offspring produced by Asexual is identical(clone)
What are the 4 things you need before you sit down?
A Pencil or Pen
Your Laptop
Your Charger (If laptop is under 50%)
Your Notebook
(WORTH DOUBLE) Meiosis is what reproduction
Sexual Reproduction
What we call DNA when it is tightly folded up into a compact shape that we can see with a light microscope
A chromosome
The number of parents involved in sexual reproduction is...
two parents
The number of parents involved in asexual reproduction
One
Two things that sexual and asexual reproduction have in common
Offspring are created and DNA is passed down
What does DNA mean?
DNA is a short term for deoxyribonucleic Acid
What is the relationship between the terms chromosome, DNA, genes, and heredity?
The DNA is found in our Chromosomes. DNA and traits are related because DNA provides the code for traits. DNA is the set of instructions that determine your eye color, nose size/shape, skin color, and many other traits.
This is a form of sexual reproduction in plants. (Hint: Bees do it)
What is pollination?
The type of reproduction used by bacteria and ameobas. (Hint: Cutting off limb and new one growing)
budding
What type of reproduction can happen faster: sexual or asexual reproduction?
asexual reproduction
Mitosis is what reproduction
Asexual Reproduction
A section of DNA that contains the codes for a proteins traits
a gene
Are the offspring exactly the same or different from the parents? Why?
The offspring are different from the parents because they inherit DNA from both parents.
What are some advantages of Asexual Reproduction?
Fast process
No mate required
**DOUBLE POINTS** What traits do you think you inherited, or received, from your parents? (Entire Team Must Answer)
Whole group names a trait from parents.
Suppose a human child had a mother with dyed-pink hair and a father who was missing a finger (lost in an accident). Would the child inherit these traits?
No, the child would not inherit these traits. The pink hair and missing finger are examples of acquired traits, traits that are not passed down. The mother changed her hair color and the father lost a finger. These traits are not in their genes to be passed down to their offspring.
(WORTH DOUBLE) What is located in the cell and holds chromosomes
The Nucleus
(WORTH DOUBLE) Why is sexual reproduction used more?
(Think about the pineapple spray)
Sexual reproduction is used more due to less risk of extinction =greater genetic variation
Why is asexual reproduction used less?
Asexual reproduction is used less because of greater risk of extiction

*CRITICAL CONTENT*
Some fungi are able to reproduce both sexually and asexually. Which type of reproduction would best benefit the fungi if the environment is changing?
A. Sexual reproduction can produce many offspring quickly in a changing environment.
B. Asexual reproduction can occur quickly, so it wouldn't matter if the environment changes.
C. Sexual reproduction would produce genetically different offspring which gives the fungi a greater chance to survive.
D. Asexual reproduction would produce genetically identical offspring which gives the fungi a greater chance to survive.
C. Sexual reproduction would produce genetically different offspring which gives the fungi a greater chance to survive.
