What is a lowercase letter.
What is the definition of variation?
The differences that exist between organisms.

Answers will vary-
Examples: strawberry plant, spider plants, sweet potatoes
What is the difference between self-pollination and cross-pollination?
Self-pollination: The process of transferring the pollens from anther to stigma in the same flower.
Cross-pollination: The transfer of pollen grains from the anther of a flower to the stigma of another flower in a different plant.

There needs to be two of this gene for it to be expressed.
What is recessive.
What is the definition of trait?
An observable characteristic that you inherit.
What are the benefits of sexual reproduction?
What are the benefits of asexual reproduction?
Sexual reproduction: Offspring are more likely to survive.
Asexual reproduction: Faster/easier
Which type of reproduction produces more genetic diversity? Explain your answer.
Sexual reproduction because the offspring's DNA is composed of 50% of its mother and 50% of its father's.
How old is Ms. B?
34!
When this gene is present, it is always expressed.
What is dominant.
What is the definition of DNA?
The unique genetic code that is passed down from an organisms’ parents.
What are the risks of sexual reproduction?
What are the risks of asexual reproduction?
Sexual reproduction: It takes a long time and it requires two individuals from the same species.
Asexual reproduction: No genetic variation.
What is the definition of sexual reproduction?
Genetic information from both parents are combined. Offspring are genetically different from the parents.

Solve a Punnett Square for Yy by yy.
What percent will the offspring have the dominant trait?

What is a gene?
A section of DNA that codes for a particular trait.
Plants that reproduce with flowers use what type of reproduction?
Sexual reproduction
Create a Venn Diagram that compares sexual and asexual reproduction.
Sexual: 2 parents, genetic variation, takes longer
Both: Types of reproduction in living organisms & DNA is passed from parent to offspring
Asexual: 1 parent, no genetic variation, faster, easier & requires less energy
