Genetics Review

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

Why did Gregor become a Monk?

• He thought the robe would look cool

• He wanted to rebel against his parents

• He was called by God

• For free college

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

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.

Which of the following is correct?

• Yy is homozygous dominant.

• YY is heterozygous.

• yy is homozygous recessive.

• YY is homozygous recessive.

Which of the following represents a heterozygous genotype?

• Aa

• AA

• aa

• Ab

The dominant trait in this punnett square is

• yellow pea seeds
• green pea seeds
• there is no dominant seed

In a flowering plant species, red flower color (R) is dominant over white flower color (r). What is the genotype of any red-flowering plant resulting from this species?

• rr
• R
• RR
• RR or Rr
