Explain how corn can be used as an example of Mendel's law of independent assortment.

Answer:

Corn acts as an example of Mendel’s law of independent assortment because each kernel on an ear of corn is an individual offspring resulting from a unique fertilization event. Traits such as kernel color and texture are controlled by different genes that assort independently during the formation of gametes. Consequently, each kernel inherits traits independently, receiving one allele for each characteristic from each parent. This leads to the variety of color and texture combinations seen across the kernels on a single cob.

A
Each kernel of corn inherits traits independently.
B
Each kernel of corn receives one allele from each parent for the traits of color and texture.
C
Corn can have multiple kernel colors because each kernel is independently formed.

Why did Mendel study pea plants?

Answer:

Pea plants were easy to grow, had short generation times, produced many offspring, and showed clear contrasting traits that Mendel could study through controlled breeding.

15

What is the definition for "hypothesis"?

A
a scientific concept that explains what patterns of behavior will be seen through repeated investigations
B
a hypothesis or group of related hypotheses that can be accepted as true based on repeated experimentation with similar results
C
a possible explanation or answer to a scientific question that is based on prior knowledge or research and is testable
16

Before testing the pea plants, Mendel formed a five-part hypothesis. What did Mendel include in his hypothesis? Check all that apply.

A
A pair of factors (known as genes) control traits.
B
One gene comes from each parent for every trait.
C
Each trait is passed from generation to generation.
D
Some traits are passed together from generation to generation.
E
When gametes are formed, genes separate.
F
If there are two unlike genes, one may be seen while the other is hidden.
17

Explain the difference between a theory and a law.

Answer:

A scientific law describes a consistent pattern observed in nature, while a scientific theory explains how or why that pattern occurs. Both are supported by evidence, and a theory does not become a law.

18

Mendel studied pea plants for particular traits. When observing the results of his experiments, he created two laws of inheritance. How is a scientific law formed?

Answer:

A scientific law is formed when repeated observations and experiments consistently support a pattern or relationship in nature.

19

Explain how the alleles were passed from parents to offspring.

Answer:

Each parent passed one allele to the offspring. The Gg parent passed the dominant G allele, and the gg parent passed a recessive g allele, producing a Gg offspring with green pods.
