Describe the difference between sexual and asexual reproduction.
a. Sexual reproduction requires one parent, but asexual requires two.
b. Sexual reproduction produces identical offspring, but asexual produces offspring that are a combination of both parents.
Sexual reproduction requires two parents, but asexual requires one.
Sexual reproduction is faster than asexual reproduction.
Which organism would you classify as sexually reproducing?
a. A strawberry plant that reproduces through runners in the ground.
b. A starfish that reproduces by breaking off and regenerating parts of its body.
c. An amoeba that splits through binary fission.
d. A chicken egg that is fertilized by a rooster
How does the DNA of an asexually reproducing plant relate to its parent(s)?

b. Its DNA has mutations.
c. Its DNA is identical to its parent
Bacteria reproduce by dividing through a process called binary fission. Which type of reproduction is described above?
a. Sexual
b. Asexual
c. Meiosis
d. Fertilization
Which cell aids in sexual reproduction?

b. Skin cell
c. Nerve cell
d. Muscle cell
Organisms produced asexually are (identical/similar) to parent organisms.
identical
similar
Which is an advantage of sexual reproduction?
a. The population can reproduce more rapidly
b. It takes time and energy to find a mate.
c. Only one parent is required to reproduce.
d. There is increased genetic variation.
If the fallopian tubes were completely blocked on both sides, the most likely result would be that...
1. egg and estrogen production would stop
2. sperm and insulin production would stop
3. fertilization would not occur
4. an embryo would develop
The paramecium is a single-celled organism that reproduces asexually. The offspring of a paramecium usually contain
1. only half of the genes of the parent cells
2. genetic material identical to that of the parent cell
3. more DNA than the parent cell
4. fewer mutations than the parent cell
Which statement best explains how each of the different cell types can develop from the same embryo?
1. The cells have identical genetic instructions, but different parts of these instructions are being expressed in each cell.
2. The cells have identical genetic instructions, and all parts of these instructions are being expressed in each cell.
3. The cells are produced by asexual reproduction and contain identical genetic instructions.
4. The cells contain genetic instructions from two different parents and will express the instructions from one parent, only.
Two kittens in a litter are genetically different from each other and their parents. These genetic differences are most directly due to ?
1 sexual reproduction
2 asexual reproduction
3 cloning
4 evolution
Sexualy reproducing orgaisms pass on genetic information such as
1. a long chain of amino acids
2. a complex series of inorganic proteins
3 .sequence of complex sugars
4 .sequences of the bases A ,T, C, and G
6.) Which sequence represents the order of some events in human development?
(1) zygote → sperm → tissues → egg
(2) fetus → tissues → zygote → egg

When an organism reproduces asexually, it usually has:
two parents, and the same chromosome number as each parent
two parents, and twice as much DNA as either parent
only one parent, and the exact same DNA as the parent
only one parent, and half as much DNA as the parent

sexual
pedigree
a sexual

50%
what is it called when the sperm and egg come together and form a zygote?
meiosis
mitosis
fertilization
gametes
only 1 parent and is identical to each other
sexual
asexual
