Master NEET Zoology with topic-wise questions. Tailored for NEET students, these questions strengthen your Biology preparation.
In a plant species that reproduces through apomixis, a mutation arises in a somatic cell that confers resistance to a fungal pathogen. What is the likelihood that this resistance trait will be passed on to the offspring?
Low, as somatic mutations are rarely heritable.
High, as apomixis bypasses meiosis and fertilization.
Dependent on whether the mutation is dominant or recessive.
Zero, as apomixis only involves the maternal gametophyte.
Which statement regarding the genetic predisposition to allergies is MOST accurate?
A single gene mutation is usually responsible for most allergic conditions.
Genetic factors play a minimal role in the development of allergies; environmental factors are primarily responsible.
Allergies are strictly inherited following Mendelian patterns of inheritance.
Multiple genes interacting with environmental factors contribute to the development of allergies.
Which of the following is NOT a key factor influencing the process of natural selection?
Variation within a population
Inheritance of traits
Differential reproductive success
Equal survival rates for all individuals
Which observation provides evidence against Lamarck's theory of evolution?
Organisms can adapt to their environment.
Evolution occurs over long periods.
Traits acquired during an organism's lifetime are generally not passed on to offspring.
Fossil records show changes in species over time.
