UHS MDCAT 2017 Paper ( PART 6 ) 1. The condition in which the heterozygote has a phenotype intermediate between contrasting homozygous parents is called as: Over dominance Incomplete dominance Dominance Co- dominance 2. The interaction between different genes occupying different loci is: Pleiotropy Co-dominance Dominance Epistasis 3. Locus stands for: Position of gene on homologous chromosome Close regions of same chromosome Regions of chromosomes Position of an allele within a DNA molecule 4. Self fertilization of F-1 dihybrids, following independent assortment of alleless result in: 9/16 Tall-round ; 3/16 Dwarf-round 3/16 Tall-round ; 3/16 dwarf-wrinkled 9/16 Tall-wrinkled ; 3/16 dwarf round 3/16 Tall-wrinkled ; 3/16 dwarf-round 5. As a result of cross-fertilization of a true breeding pea plant having purple coloured flowers with that of white coloured flowers, the offspring will have flowers with: 1/4 purple ; 3/4 white 1/4 white ; 3/4 purple All white all purple 6. The gene for red-green colour blindness is present on: X-chromosome Y-chromosome Autosome 7 Autosome 9 7. Which of the following structure is present in both plant and animal cell but is absent in prokaryotic cells: Centrioles Plastids Microtubule Sieve-tubes 8. Cillia and flagella are absent in: Higher plants Viruses Lower animals Bacteria 9. DNA molecule in prokaryotes is: Single, circular, double stranded, membrane bound Single,circular, double stranded molecule not bound by membrane Double, circular molecule Linear double stranded molecule 10.

assalamualaikum sir this website is amaizng….for MDCAT students Butt there is an issue with key kindly recheck it as in part 7 mcq no 8 is marked wrong ………….protien molecules mostly made os 20 types of amino acids rather than 25
