Gregor Mendel was the person who found the fundamental principles of genetics.
- True
- False
Correct Answer

A. True

Explanation

Gregor Mendel is widely recognized as the founder of modern genetics. In the mid-19th century, Mendel conducted experiments with pea plants and discovered the basic principles of inheritance. His work laid the foundation for understanding how traits are passed from one generation to the next. Mendel's findings, which included concepts such as dominant and recessive traits, segregation, and independent assortment, revolutionized the field of genetics and continue to be taught and studied to this day. Therefore, the statement that Gregor Mendel found the fundamental principles of genetics is true.

_________ are various alternative forms of a gene for the same trait.

Correct Answer
alleles, allele

Explanation
Alleles are various alternative forms of a gene for the same trait. An allele is a specific version of a gene that determines a particular characteristic or trait. Different alleles can result in different expressions of the trait, such as different eye colors or blood types. The presence of multiple alleles allows for genetic diversity within a population and contributes to the variation observed in individuals.

Recessive traits are the ones that are expressed.
- True
- False
Correct Answer

A. False

Explanation

The given statement is false. Recessive traits are not the ones that are expressed. In genetics, recessive traits are only expressed when an individual inherits two copies of the recessive allele. If an individual inherits one copy of the recessive allele and one copy of the dominant allele, the dominant trait will be expressed. Therefore, recessive traits are only expressed in individuals who are homozygous for the recessive allele.

A way to predict the offspring of 2 individuals is called a ________.

Correct Answer
punnett square

Explanation
A Punnett square is a tool used in genetics to predict the possible combinations of alleles that offspring can inherit from their parents. It is a grid that organizes the different alleles of each parent and shows all the possible combinations that can occur when the parents reproduce. This allows scientists to determine the probability of certain traits or genetic conditions being passed on to the next generation.
