Question 1:

What is the definition of genotype?

Explanation: B) The genotype refers to the genetic makeup of an individual, specifically the combination of alleles that an individual possesses for a particular trait.

Question 2:

What is the definition of phenotype?

Explanation: A) The phenotype refers to the physical appearance or observable traits of an individual, which are determined by the interaction between an individual's genotype and the environment.

Question 3:

Which of the following statements about genotype and phenotype is true?

Explanation: C) Genotype determines phenotype. The genetic makeup of an individual (genotype) determines the physical appearance and observable traits (phenotype) that the individual displays.

Question 4:

If a plant with the genotype AaBb produces gametes, how many different gamete combinations can be formed?

Explanation: D) If a plant with the genotype AaBb produces gametes, it can form 4 different gamete combinations. The genotype AaBb consists of two genes (Aa and Bb), and each gene can segregate independently during gamete formation, resulting in 2^2 = 4 possible combinations.

Question 5:

Which of the following is an example of a genotype?

Explanation: C) TT. The combination of alleles represented by the letters T is an example of a genotype. In this case, TT represents a homozygous genotype for a particular trait.
