Q

What does “dominant” mean when referring to genetics?

A

A genetic factor that blocks or hides another genetic factor. It is stronger and overpowers the ‘recessive’ trait.

Q

When you cross a heterozygous dad with a heterozygous mom, what is the ratio of offspring with the dominant phenotype?

A

3:1

1 offspring is homozygous dominant
2 offspring are heterzygous
1 offspring is homozygous recessive

The homozygous dominant and the 2 heterozygous offspring will show the dominant trait.

Q

If B represents the dominant allele (brown eyes) and b represents the recessive allele (blue eyes) what is a homozygous dominant individual’s phenotype?

A

Brown eyes

17
Q

If B represents the dominant allele (brown eyes) and b represents the recessive allele (blue eyes) what is a heterozygous individual’s phenotype

A

Brown eyes

18
Q

In a chemical equation, what do you call the materials you begin with?

A

Reactants

19
Q

What are the reactants in photosynthesis?

A

Carbon Dioxide, Water, and Sunlight

20
Q

Using the letter T, what would the genotype of a homozygous dominant individual be?

A

TT

21
Q

Where was Mendel from?

A

Austria

22
Q

What form of energy is released during respiration?

A

ATP (adenosine triphosphate)

23
Q

Name 4 traits Mendel studied in pea plants.

A

flower color seed color seed shape
lower position pod shape pod color
stem length

24
Q

What is an allele?

A

Different forms of the same gene. You get one from each parent that combine to determine what trait you will show.

25
Q

What are pedigrees used for?

A

To show phenotypes of genetically related family members. Often times they are used in the breeding of dogs, horses, and cattle (bulls).

26
Q

What are some positives about the use of GMOs?

A

It reduces the need for pesticides, it increases crop yield and therefore help with food shortages, it can help reduce soil erosion.

27
Q

Where does cellular respiration take place

A

mitochondria

28
Q

What is the chemical formula for respiration?

A

C6H12O6 + 6O2 yields ATP + 6CO2 + 6H2O

29
Q

What is the 1st step of mitosis?

A

Prophase

30
Q

During what stage of mitosis do the spindle fibers begin pulling chromatids to opposite sides of the cell?

A

Anaphase

31
Q

What are the two stages that make up the cell cycle?

A

Interphase and Mitotic Stage

32
Q

What happens during Interphase?

A

The cell grows and duplicates its DNA and organelles.

33
Q

Explain the process of cytokinesis in plant cells.

A

Because plant cells have a cell wall, they cannot pinch together like they do in an animal cell. Instead a cell plate forms down the middle. Then the cell wall uses the cell plate as a guide and forms right up next to the cell plate. The cell plate then disappears and you have 2 identical new plant cells.
