Meiosis results in a change in chromosome number which can be written as

"2n to n."

The four o'clock flower is an example of incomplete dominance. R = red, r = white, and Rr = pink. If two hybrids are crossed, what are the chances that an offspring will have pink flowers?

50%

In humans, brown eyes (B) are dominant over blue eyes (b). A brown-eyed woman who has a blue-eyed child would have the genotype

Bb

A geneticist finds three copies of chromosome 21 in the karyotype of a patient, leading to the conclusion that the patient has what anomaly?

Down syndrome

In a Mendelian monohybrid cross, which generation is always completely heterozygous.

F1

Mitosis and meiosis both produce genetically identical daughter cells.

FALSE

What role does oxygen play in cellular respiration?

It acts as the final electron acceptor in the electron transport chain.

Water is split and oxygen is released during which process in photosynthesis?

Light Reactions

Which of the following are coenzymes which assist in cellular respiration?

NAD+ and FAD

What is(are) the end product(s) of the light reactions in photosynthesis?

NADPH and ATP

The last step in the Calvin cycle is

RuBP regeneration.

Why is water split during photosynthesis?

To replace the electron lost in photosystem II

What material(s) are put into the Krebs Cycle?

acetyl groups

Gametes and spores

are haploid.

If a new kind of slug were found which had a system of sex determination just like that of humans, it would have

both sex chromosomes and autosomes.

The major goal of the Calvin cycle is to produce what material?

carbohydrate

During the process of photosynthesis, which of the following products are formed?

carbohydrate and oxygen

Which of the following is reduced as a result of the Calvin cycle?

carbon dioxide

In a study of the raw materials used for photosynthesis, what two kinds of molecules would be studied?

carbon dioxide and water

Which of the following are the end products for cellular respiration?

carbon dioxide and water

Which of the following terms would be used for an allele which can mask the expression of another allele?

dominant

Which of the following phases takes place entirely outside the mitochondria and is considered to be anaerobic?

glycolysis

The second meiotic division is essentially a mitotic The second meiotic division is essentially a mitotic division except for the fact that the cells produced are

haploid.

When an organism has two different alleles for a particular trait, which term best describes this condition?

heterozygous

When an organism has two identical alleles for a trait we would refer to this condition as:

homozygous

What is the significance of the cristae in the mitochondria?

increase surface area, therefore increasing the electron transport chain

Mitosis and meiosis differ in that

mitosis does not change the number of chromosomes per cell.

When a trait has more than two different forms, the gene has

multiple alleles

What are the reactants involved in cellular respiration?

oxygen and glucose

Which of the following terms is represented by word descriptions, such as brown or tall?

phenotype

When two or more sets of alleles affect the same trait, it is referred to as

polygenic inheritance.

Crossing-over occurs during which of the following phases?

prophase I

As a result of glycolysis, one molecule of glucose is broken into two molecules of

pyruvate

Flattened sacs within the chloroplast are known as

thylakoids

The ATP which is made during the electron transport chain is made at which site?

ATP synthase complex

What are alleles?

alternative forms of a gene for a single trait, such as blue eyes and brown eyes

A doctor inserts a long needle into the uterus and removes some fluid to perform a genetic test. Which of the following procedures did the doctor perform?

amniocentesis

An organism that has more or less than the normal number of chromosomes is called:

aneuploid.

The substance that initially traps solar energy in photosynthesis is

chlorophyll.

Which part of cellular respiration produces the greatest amount of ATP?

electron transport chain

What role do NADH and FADH2 play in the process of cellular respiration?

They carry electrons to the electron transport chain.

In humans, brown eyes (B) are dominant over blue eyes (b). If a homozygous brown-eyed woman mates with a homozygous blue-eyed man, what would be the chances of producing a blue-eyed child?

0%

What is the net yield of ATP from glycolysis of one glucose molecule?

ATP

The reason that deciduous leaves turn red and yellow in the fall is

When chlorophyll breaks down, the red and yellow pigments which are already present become visible.

When two different dominant alleles are both fully expressed in the phenotype, it is referred to as

codominance.

The order of the major pathways and reactions of cellular respiration is

glycolysis-preparatory reaction-Krebs cycle-electron transport chain.
