question 1
Question #1
  • a. Evolution
  • b. Heredity
  • c. Taxonomy
  • d. Diseases

Genetics is the study of:

question 2
Question #2
  • a. GG
  • b. Mm
  • c. bb
  • d. zz

Which of the following allele pairs are considered heterozygous:

question 3
Question #3
  • a. Pure
  • b. Complicated
  • c. Hybrid
  • d. Homozygous

_____ is another term for heterozygous

question 4
Question #4
  • a. bb
  • b. Tt
  • c. GT
  • d. Ab

Which of the following are considered pure?

question 5
Question #5
  • a. Predict exactly what the offspring will look like
  • b. Predict what offspring could look like
  • c. Determine the exact ratio of phenotypes
  • d. Determine the exact ratio of genotypes

Punnett squares:

question 6
Question #6
  • a. Meiosis occurs in two steps
  • b. Polyploidy can be beneficial in agriculture
  • c. Genetics is too complicated to predict
  • d. Factors for different traits are inherited
  • independently of one another

Which was concluded by Mendel as a result of his genetic research?

question 7
Question #7
  • a. Law of Segregation
  • b. Law of Probabilities
  • c. Law of Dominance
  • d. Law of Independent Assortment

What law states that during gamete formation, genes for different traits separate without influencing each other’s inheritance?

question 8
Question #8
  • a. Twins
  • b. Gametes
  • c. Hybrid
  • d. Polyploidy

If an organism has one or more extra sets of chromosomes, they are considered:

question 9
Question #9
  • a. 1
  • b. 2
  • c. 3
  • d. 4

Two genetically identical plants were crossed. The genotypic ratios of offspring are seen in the Punnett square.How many of the offspring look like the parents?

question 10
Question #10
  • a. Tt
  • b. tt
  • c. Freckles
  • d. Exercise Routines

Which of the following is a phenotype?

question 11
Question #11
  • a. tt for mom and Tt for dad
  • b. Tt for mom and Tt for dad
  • c. TT for mom and TT for dad
  • d. TT for mom and tt for dad

Tall is dominant over short.

If mom is short and dad is heterozygous tall, what are their genotypes?

question 12
Question #12

If Black is dominant over blonde, what are the possible percentages for each phenotype in this cross?

  • a. 25% Black/50% blonde/25% brown
  • b. 75% Black/25% Blonde
  • c. 25% Black/75% Blonde
  • d. 25% BB, 50% Bb, 25% bb

question 13
Question #13
  • a. 50% TT and 50% Tt
  • b. 75% Tt and 25% Tt
  • c. 50% Tall and 50% short
  • d. 100% Tall

If Tall (T) is dominant over short (t), and a homozygous tall organism crosses with a heterozygous organism, what are the possible phenotypes of the offspring?

question 14
Question #14

A red flower and a white flower reproduce (shown in the punnett square below). Create a punnett square if one of the offspring below self-fertilizes. What percent of the offspring could be red?

  • a. 25%
  • b. 50%
  • c. 75%
  • d. 100%

  • c. 0:1 brown to blue
  • d. 1:2:1 BB to Bb to bb

If a Brown eyed grasshopper (Bb) were crossed with a Brown eyed grasshopper (Bb) what would be the resulting phenotypic ratio?

Brown is dominant over blue
