Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 25-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

Untimed

Every question on one page, loading as you scroll. Choose an option and see straight away whether it was right.

  • No timer. Nothing to start and nothing to submit. Stop whenever you like.
  • Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
  • Solutions in place. The explanation, and the video where one has been added, sit under the question.
  • Open to guests. Normal practice needs no sign-in.

Timed CBT

The computer-based test format: one clock, a question palette, and a score the moment you submit.

  • A clock that does not pause. 25 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
  • Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
  • Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
  • Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.

About this test

Genetics GK Quiz Level 1: Heredity and Mendel Basics for Beginners

Heredity and variation form the core of this Genetics GK Quiz Level 1, a beginner set in General Awareness biology. It checks basic ideas from Mendel's garden pea experiments, dominant and recessive traits, human sex chromosomes and early evidence of evolution. Aptitude360 gives a clear explanation with every question.

What this beginner genetics quiz covers

  • Heredity as the reliable passing of traits and variation as small differences among offspring
  • Why sexual reproduction creates more variation than asexual reproduction
  • Mendel's garden pea experiments: tall and short plants, seed shape, seed colour and flower colour
  • Gene pairs written with capital and small letters, and the resulting plant height
  • Sex chromosomes in humans, temperature-based sex determination in some reptiles and animals that change sex
  • Acquired traits, homologous and analogous organs, and fossils

Key genetics concepts for General Awareness

  • A dominant trait shows with one copy, a recessive trait needs both copies
  • Mendel's idea that each trait is controlled by two copies of a factor
  • The father's X or Y chromosome decides whether the child is a girl or a boy
  • Acquired traits are not inherited because they do not change the DNA of reproductive cells
  • Bird and bat wings are analogous, while forelimbs of vertebrates are homologous

How to revise genetics basics

  • Practise writing gene pairs for tall and short pea plants until you can predict height instantly
  • Keep a two-column note separating homologous and analogous organs with one example each
  • Remember that the mother always passes an X chromosome

Who should take this Level 1 genetics set

Students starting General Awareness biology for competitive exams will find this a good first check before moving to higher levels.

FAQs about Genetics – GK Quiz with Answers – Level 1

What is genetics in biology?
Genetics is the branch of biology that studies heredity and variation. It explains how traits pass from parents to offspring.
Who is known as the father of genetics?
Gregor Johann Mendel is called the father of genetics. He worked out the basic rules of inheritance through experiments on garden pea plants.
What is the difference between dominant and recessive traits?
A dominant trait appears even when only one copy of its factor is present. A recessive trait appears only when both copies are recessive.
How is the sex of a child determined in humans?
The mother always gives an X chromosome. If the father gives an X, the child is a girl, and if he gives a Y, the child is a boy.
