MCQ
Which of the following statements are correct ?
(A) Multiple step large mutation is called saltation which caused speciation.
(B) Hardy-Weinberg principle states the concept that frequency of occurence of alleles of a gene in a population remains constant from generation to generation.
(C) The total genes and their alleles in a population constitute gene pool.
(D) According to Hardy-Weinberg principle, sum total of all the allelic frequencies is one.
(E) If in a diploid organism, p and q represent the frequency of allele A and a, then probability that allele 'A' will appear on one chromosome and allele 'a' on another chromosome is 2pq.
(F) The five factors that affect Hardy-Weinberg equilibrium are gene migration, genetic drift, mutation, genetic recombination and natural selection.
(G) When original drifted population becomes founders by any chance event, then effect is called founder effect.
(H) When natural selection causes more individuals to acquire value other than mean character value it is called disruptive change and when it causes more individuals to acquire peripheral character value at both ends of the distribution curve, it is called directional.
(I) Jawless fish probably evolved around 350 bya.
(J) The first organisms to invade land were animals.
