Genetics is the study of which of the following?

  1. Heredity
  2. Nutrition
  3. Digestion
  4. Behaviour
Show answer and solution

Correct answer: A. Heredity

1. Heredity means the passing of characteristics from parents to offspring. 2. Genetics is defined as the study of heredity, so heredity is the correct match. 3. Nutrition and digestion deal with how food is used, not with how traits are passed on. 4. Behaviour is a separate field of biology and is not the definition given. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 12 "Mendel's Experiments and Heredity", Introduction_

Which organism did Mendel settle on as the primary model system for his inheritance work?

  1. The honeybee
  2. The fruit fly
  3. The garden pea
  4. The snapdragon
Show answer and solution

Correct answer: C. The garden pea

1. Mendel began in 1856 with inheritance patterns in honeybees and plants. 2. He ultimately settled on pea plants as his primary model system. 3. Fruit flies became a model organism for later workers, not for Mendel. 4. Snapdragons appear as an example of incomplete dominance, not as Mendel's model. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 12 "Mendel's Experiments and Heredity", section 12.1 Mendel's Experiments and the Laws of Probability_

A true-breeding pea plant is one that does what?

  1. Produces only sterile seeds each season
  2. Produces gametes that carry no alleles
  3. Produces twice the normal seed number
  4. Produces offspring that look like the parent
Show answer and solution

Correct answer: D. Produces offspring that look like the parent

1. True-breeding lines arise from repeated self-fertilisation, which makes them highly inbred. 2. Such plants always produce offspring that look like the parent. 3. Sterile seed and doubled seed number describe fertility, not breeding true. 4. Gametes always carry alleles, so that option describes nothing real. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 12 "Mendel's Experiments and Heredity", section 12.1 Mendel's Experiments and the Laws of Probability_
