Parts of a cell that are most likely involved with inherited traits
What is Chromosomes, genes, and nucleus?

Define heredity. Provide at least one example that demonstrates heredity.
Heredity is the passage of genetic instructions from one generation to the next generation.
offspring will receive one gene for each trait from each of their parents. The offspring are a combination of traits from the parents. Only the dominant traits are exhibited, while the recessive traits are masked. For example, a human may receive the dominant trait for eye color from the father and the recessive trait for eye color from the mother.

The amoeba is a unicellular protozoan with no fixed shape. It moves by constantly changing the shape of its body. One type of amoeba, Amoeba proteus, reproduces asexually through a process known as binary fission. The cell divides into two separate cells; the original parent cell and the new cell. describes the new amoeba cell
The new amoeba cell is genetically identical to the parent amoeba cell.

Will offspring look identical or different in sexual reproduction?
different

A student is creating a graphic organizer to explain the result of offspring from sexual reproduction. What information would be incorrect if it was placed in the student’s graphic organizer?
F. Requires two cells from different parents
G. Creates genetically uniform offspring
H. Offspring have a better chance for survival
G. Creates genetically uniform offspring

Which of the following cell components are most involved in determining an organism's traits
Chromosomes

An organism inherits its genetic instructions from the
organism's parents

a possible disadvantage of asexual reproduction
Results in low genetic variation of the species

Which of the following is not an example of heredity?
A. Lions show their cubs how to hunt for prey.
B. Bacteria reproduce asexually to create cells identical to the parent cell.
C.A boy who is 5 feet, 10 inches is taller than his father who is 5 feet, 8 inches tall.
A. Lions show their cubs how to hunt for prey.

Which of the cell components is least likely to affect the visible traits of an organism?
Mitochondria

The passage of genetic instructions from one generation to the next is known as
heredity

Hydra reproduce by a process known as budding, as shown in the diagram below. This process is the formation of a new individual that is a clone of the parent.
This type of reproduction is
asexual

Division of an amoeba into two amoebas. What type of reproduction?
Asexual Reproduction
300
Jellyfish are soft bodied, free swimming, aquatic animals. They reproduce sexually by releasing egg and sperm into the water. The egg and sperm unite in fertilization and create a new jellyfish polyp.
Which of the following best describes a jellyfish polyp?
Which of the following best describes a jellyfish polyp?
A. The jellyfish polyp will be genetically identical to the parent jellyfish.
B. The jellyfish polyp will be a diverse combination of the parent jellyfish genetic material.
B. The jellyfish polyp will be a diverse combination of the parent jellyfish genetic material.

Which cell components are responsible for the inherited traits that a pea plant possesses?
DNA, nucleus, chromosome

In sexual reproduction, how many genes does an offspring receive for each trait
2. One from each parent
400
A trait will provide an advantage in EVERY environment. True or False
False

Sexual reproduction —
F. results in genetic variation in the offspring
G. produces offspring that are identical to the parent
H. decreases the chances of survival of the species
J. results in genetic material being donated to offspring by only one parent
F. results in genetic variation in the offspring

Where is the genetic material that determines the inherited traits of an organism located inside of a eukaryotic cell?
Nucleus

A student who loves football plays for his school team. His dad played football throughout college. He loves school, and his favorite subjects are reading and math. His father’s favorite subject was always reading, while his mother preferred math. His mother and father both have short, curly, brown hair. He and both of his parents have freckles on their cheeks.
What traits did Brian inherit from his parents?
I. Ability to play football
II. His love for math
III. Short hair
IV. Curly hair
V. His love for reading
VI. Brown hair
VII. Freckles
IV, VI, VII (curly hair, brown hair, and freckles)
