The ABO blood groups in humans are determined by a multiple-allele system in which 1 and I" are codominant and are both dominant to P. A neaboen infant is type A. The mother is type O. Possible phenorypes of the father are a) A, H, or AR. b) O only. ) A oe All. d) A or O. e) A, I, or O. 3. Which statement about complementary base pairing in not true? a) In DNA, T pairn with A. b) Purines pair with purines, and pyeimidines pair with pyrimidines. * Complementary base pairing plays a role in DNA repleation d) In DNA, C pair with G. O The base pairs are of equal kength. The phenomenon of "independent asortment" refers to a) expression at dhe same stage of derekpment b) associacion of a procein and a DNA sequence implying related function ) unlinked transmission of genes in crosses resudking from being located on different chromosomes, or far apart on the same chromosome. 4) ssociation of an RNA and a protein implying related function e) independent kocation of genes from each ocher in an interphase cell 5. Mendel's law of segregation, as applied to the behaviour of chromosomes in meiosis, means that: 4 pairing of homologous chromosomes will comert one allele inco the other, leading to separation of the types. b) alleles of a gone separate from cach other when homologous chromosomes separate in meiosis 1, at in melonis Il if there is a single crossover between the gene and the centromere. ) genes on the same chromasome will show 50% recombination d) alleles of a gene will be linked and passed on together through meiosis ©University of Trinidad and Tobago Term 2 2016/2017 Final Examination LFSC1002 Page 2 of 15 6.
