Answer 1

26) (a) - genes are passed form one generation to the next generation, so it is responsible for the development of new traits or functions which is the main source of evolution.

27) (a) - anatomical (ecological and behavioral isolation is possible)

28) (d) - female always choose flashy mates is wrong statement. ( there should be random mating and no sexual selection for a population to be in Hardy Weinberg Equilibrium.)

29) (c) - after 1 millions years (DNA is not properly readable after 1 million years)

30) (c) - leaves (helps in camouflage and to catch prey easily)

31) (d) - both b+c (horizontal gene transfer and gene duplication helps in new gene formation)

32) (a) yes (transcription factor is basically the proteins which is used for both on/off of genes.)

33) (b) - mutation arose that allow defensin to attack new pathogens (plays major roles in defensive mechanisms in variety of organisms including plants, invertebrates and vertebrates from pathogens)
