Name 2 facts about asexual reproduction.
- It involves only 1 parent
- The offspring are genetically identical
- Allows organisms to reproduce very quickly
300
What idea does this definition describe?
When humans decide which traits to select based on their preferences
artificial selection

In a certain plant type, the tall (T) trait is dominant.
On your paper, cross a homozygous tall plant (TT) and a homozygous short plant (tt). What percentage of the offspring are tall?
100 %
300

Sexual reproduction

Gregor Mendel knew that pea plants reproduce sexually. Because of that, what did he figure out about traits in plants?
He discovered that traits are passed from one generation to the next.

How are dogs and corn examples of artificial selection?
Because humans have bred/cultivated them for the traits they wanted, not for what would have happened naturally.
400
In a certain type of plant, tall (T) is the dominant trait
On your paper, cross two heterozygous tall plants (Tt). What is the percentage of having a tall plant in the offspring?
75 %

Why is the basilosaurus considered an example of a transitional fossil?
Because it has characteristics of both the ambilocetus (ancient whale) and the cetacea (modern whale)

According to this phylogenetic tree, which animals have an amniotic egg?
turtle and leopard

Based on these descriptions, which is describing an organism that reproduces asexually?
A. Pollen from one flower pollinates an egg of another flower to produce seeds.
A female fish lays unfertilized eggs in a river, and the male arrives later to fertilize the eggs.
C. Spores are formed from two cells, each from a different and genetically unique fungal organism.
D. An amoeba splits during binary fission into two genetically identical cells.
D. An amoeba splits during binary fission into two genetically identical cells.

How are the finch's beaks an example of natural selection?
Because the birds with beaks best adapted to the available food were the ones to survive and reproduce.
500
Having dimples is a dominant trait. What genotypes would two parents with dimples have to have in order for them to have a child who does NOT have dimples? Use D for the allele.
Both parents would need to be Dd (heterozygous)
