Biology Trivia Quiz On Heredity And Evolution - Quiz

For most humans, some traits have been known to be passed from the parents to offspring, depending on whose genes are stronger between the two parents. This research on heredity has helped show the chances of a person contracting some diseases. Take up the quiz below and see what you know about hereditary and evolution. All the best!


Questions and Answers
  • 1. 

    Mendel observed 7 pairs of contrasting characters in Pisum sativum. One of the following is not a part of that. Find out.

    • A.

      Tall and dwarf

    • B.

      Yellow and green seed colour

    • C.

      Terminal and axial Flower

    • D.

      Smooth and rough stem

    Correct Answer
    D. Smooth and rough stem
    Explanation
    Mendel observed 7 pairs of contrasting characters in Pisum sativum, including tall and dwarf plants, yellow and green seed color, and terminal and axial flowers. However, smooth and rough stem is not one of the pairs of contrasting characters that Mendel observed in Pisum sativum.

    Primitive man evolved in -

    • A.

      Africa

    • B.

      America

    • C.

      Australia

    • D.

      Australia

    Correct Answer
    A. Africa
    Explanation
    Primitive man evolved in Africa. This is supported by scientific evidence such as fossil records and genetic studies. The oldest known human fossils, including those of Homo habilis and Homo erectus, have been found in Africa. Additionally, genetic studies have shown that modern humans originated in Africa and migrated to other parts of the world. Therefore, Africa is considered the birthplace of humanity and the place where primitive man evolved.

  • 3. 

    Which of the following is inheritable

    • A.

      An altered gene in sperm

    • B.

      An altered gene in testes

    • C.

      An altered gene in zygote

    • D.

      An altered gene in udder cell

    Correct Answer
    A. An altered gene in sperm
    Explanation
    An altered gene in sperm is inheritable because it can be passed on to the offspring during fertilization. Sperm cells carry genetic information, including altered genes, which can be transmitted to the zygote during conception. This altered gene can then be expressed in the offspring, leading to inherited traits or characteristics. The other options mentioned, such as altered genes in testes, zygote, or udder cells, are not directly involved in the transmission of genetic information to the next generation.

    Theory of natural selection was proposed by -

    • A.

      Charles Darwin

    • B.

      Hugo de Vries

    • C.

      Gregor Johann Mendel

    • D.

      Jean Baptise Lamarck

    Correct Answer
    A. Charles Darwin
    Explanation
    The theory of natural selection was proposed by Charles Darwin. He is known for his work on the theory of evolution, which states that species change over time through the process of natural selection. Darwin's observations and studies led him to propose that organisms with traits that are advantageous for their environment are more likely to survive and reproduce, passing on these beneficial traits to future generations. This theory revolutionized the understanding of how species evolve and adapt to their surroundings.

    Somatic gene therapy

    • A.

      Affects sperm

    • B.

      Affects egg

    • C.

      Affects progeny

    • D.

      Affects body cell

    Correct Answer
    C. Affects progeny
    Explanation
    Somatic gene therapy refers to the introduction of genetic material into the cells of an individual's body, excluding the reproductive cells (sperm and eggs). This means that any changes made through somatic gene therapy will not be passed on to future generations. Therefore, it can be concluded that somatic gene therapy affects the individual's body cells but does not affect the progeny.
