Heredity

Heredity and genetics stem from chromosomes which is genetic information in the form of genes. Chromosomes are found in the nucleus and genes are found in chromosomes.

Heredity

Genetic material helps govern inherited traits.

Multiple Choice

Some traits are inherited and others are acquired. Which of the following is an acquired trait in humans?

• Eye color

• Hair color

• Blood type

• Table manners

Multiple Choice

Which of the following organelles contains chromosomes?

• vesicle

• Ribosome

• mitochondria

• Nucleus

Multiple Choice

Genes are located on an organism's...

• vacuoles

• Lysosomes

• Chromosomes

• Ribosome

Multiple Choice

Genetic material is primarily responsible for

• Removing cell waste

• Governing inherited traits

• Creating new enzymes

• participating in digestion

Multiple Choice

Look at the diagram showing below. The alleles for the parents are missing. The parents in the diagram above have which of these alleles?

• DD and Dd

• Dd and Dd

• Dd and dd

• DD and dd

Multiple Choice

Heredity defines the passage of genetic material from...

• parent to child

• sibling to sibling

• mate to mate

• predator to prey

Multiple Choice

Recessive genes are expressed under which of the following conditions?

• Every time they are found in an organism

• In green plants that reproduce through seeds

• When asexual organisms produce a pair of offspring

• Only in the absence of dominant genes for that same trait

Multiple Choice

In humans, the gene for brown eyes is dominant over the gene for blue eyes, which is recessive. If two blue-eyed parents have six children, how many of their children will have blue eyes?

• zero

• two

• four

• six

Reproduction

Chromosomes are a huge part of reproduction and genetics. Humans have 23 pairs of chromosomes. Some animals, like goats have 30 chromosomes but when paired, their full set is equal to 60 chromosomes.

Asexual Reproduction

Asexual Reproduction

Sexual Reproduction

Sexual Reproduction

Multiple Choice

Which of these statements correctly describes one way that asexual and sexual production are different? (Hint: Step 1. Before reading the choices, recall the definition for each type of reproduction. 2. Think about how each process affects the offspring. 3. Find the choice that explains how the offspring of each type of reproduction are not the same.)

• Asexual reproduction increases genetic diversity, but sexual reproduction does not

• Asexual reproduction involves one parent, and sexual reproduction involves two parents

• Asexual reproduction increases a species’ chances of surviving unfavorable conditions, but sexual reproduction does not

• The offspring produced by asexual reproduction are not identical to each other, but those of sexual reproduction are identical to each other

Multiple Choice

Look at the diagram of sexual reproduction shown below.

Which of these statements correctly describes the genetic information in the diagram?

• Cell A is genetically identical to cell C.

• Cell B contains the same genetic material as cell C

• Cell C has the same genes from cell A and cell B

• Cells A and C contributed genetic materials to cell B

Multiple Choice

Artificial selection produces many of the vegetables we eat today. Many of the vegetables come from plants shown in the illustration below. Based on the figure which of the following is true of both cauliflower and broccoli?

• Artificial selection lead to smaller leaves

• artificial selection lead to underground bulbs

• Artificial selection lead to longer thicker stems

• Artificial selection led to larger cluster of flowers

Multiple Choice

A goat has 30 chromosomes in its sex cells. How many chromosomes make up a full set of chromosomes in goats?

• 60

• 30

• 10

• 80
