What is Mendelian genetics?

• A type of genetic mutation

• The study of plant genetics

• The process of genetic recombination

• Principles of inheritance discovered by Gregor Mendel

Explain the difference between dominant and recessive traits in Mendelian genetics.

• Recessive traits are always expressed in offspring

• Dominant and recessive traits have no difference in expression

• Dominant traits are only expressed when two copies of the dominant allele are present

• Dominant traits are expressed when at least one copy of the dominant allele is present, while recessive traits are only expressed when two copies of the recessive allele are present.

How are Punnett squares used to predict the outcome of genetic crosses?

• By consulting a horoscope to predict the outcome

• By flipping a coin to determine the outcome

• By using a crystal ball to predict the outcome

• By organizing the possible combinations of alleles from the parents.

What is a Punnett Square?

• A Punnett square is a type of crossword puzzle

• A Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment.

• A Punnett square is a type of cooking technique

• A Punnett square is a type of dance move

What is genetic variation and why is it important for a species?

• Genetic variation is the diversity in genetic material within a population, and it is important for a species because it allows for adaptation to changing environments, increases the chances of survival, and provides the raw material for evolution.

• Genetic variation is the diversity in physical appearance within a population, and it is important for a species because it leads to uniformity

• Genetic variation is the result of a single gene in a population, and it is important for a species because it causes diseases

• Genetic variation is the same in all individuals within a population, and it is not important for a species

What is the role of DNA and genes in inheritance and genetic traits?

• They determine the color of the eyes

• They control the growth of hair and nails

• They contain the genetic information that determines inherited traits.

• They are responsible for regulating body temperature
