For organisms, whose genomes are completely sequenced, the variation between the genomes can be measured from the temperature at which single-stranded DNA molecules anneal to form a double helix.P represents a melting curve when both DNA strands were taken from a mocking bird. Q represents a melting curve when one DNA strand was from a mocking bird and another from starling. I to IV represent melting curves obtained when DNA strands of different bird species shown in the cladogram were paired.State whether the following statements are true (T) or false (F).a. Curve I is likely to represent DNA duplex formed by one strand from a mocking bird and another from a thrasher.____ b. Common starlings, mynahs and catbirds form a monophyletic clade where the most recent common ancestor evolved around 20 mya.____ c. Curves II and III likely to represent hybrids between DNA of mocking bird with family Sylvoidea and family Passeroidea respectively.____ d. The greater the curve to the left of P, greater is the complementarity between the sequences.____
