BIO: Mendel & Genetics

Who is Gregor Mendel

• an Austrian Monk from the mid 1800s who contributed to the study of Genetics

• The scientist who discovered the structure of DNA

• a British scientist who discovered penicillin

• The scientist who used X-Ray Crystallography to shed light on the structure of DNA

What did Gregor Mendel study?

• Mold Spores

• Pea Plants

• Sun Flowers

• Rats

What specifically about Pea Plants did Mendel Study?

• Color of Pea Flower

• Colors of individual Peas

• Texture of Peas

• All of these

Why were pea plants perfect a study on Heredity?

• Pea plants are complex

• They were easy to study

• One gene controlled one trait. (i.e. it was simple)

• One gene was controlled by multiple traits

What did Mendel notice?

• Most pea flowers were tall, and some were purple.

• Most of the pea flowers were white, but a few were purple.

• Most of the pea flowers were purple, but a few were white.

• Most pea flowers were short, and some were white.

What was Mendel's first conclusion?

• Pea plants were inheriting a pair of genetic instructions from both parents.

• Pea plants were inheriting genetic instructions from their grandparents.

• Pea plants were inheriting genetic instructions only from their maternal parent.

• Pea plants were inheriting genetic instructions only from their paternal parent

What was Mendel's Second conclusion?

• The allele (factor) for purple flowers was stronger, or more dominant, than the white allele (factor)

• The allele (factor) for purple flowers were the same strength, equal dominance, to the white allele (factor)

• The allele (factor) for purple flowers was weaker, or more recessive, than the white allele (factor)

• The allele (factor) for white flowers was stronger, or more dominant, than the purple allele (factor)

Mendel's Law of Segregation means?

• Every person has two alleles for each trait, they segregate from each other and the dominant is passed more often.

• Every person has two alleles for each trait, Where two traits are being passed, they do not effect each other.

• Every person has two alleles for each trait, they segregate from each other and are passed down at random.

• Every person has two alleles for each trait, they segregate from each other and the recessive is passed more often.

What is Mendel's Law of Independent Assortment?

• If the recessive allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.

• The passing of allele of one trait does not affect the passing of allele of another trait.

• If the dominant allele is passed for one trait, then it is more likely that the dominant allele will be passed for the other trait.

• If the dominant allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.

What was the name of the Father of Genetics

• Gregor Mendel

• Albert Einstein

• Robert Frost

• Charles Darwin
