Genetics & Evolution Questions with Solutions

This topic covers heredity and evolution: Mendel's laws of inheritance, genes, DNA and chromosomes, sex determination, genetic disorders, theories of evolution by Lamarck and Darwin, and evidence for evolution. Exam questions commonly ask who is called the father of genetics (Gregor Mendel, who worked with pea plants), who proposed natural selection (Charles Darwin), which chromosomes determine sex in humans, and which disorders are linked to the X chromosome, such as haemophilia and colour blindness. Watson and Crick proposed the double helix model of DNA in 1953. Practise the genetics and evolution questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
