Let us consider three independently assorting autosomal genes in Drosophila: A, B and C. What is the probability that a female of genotype AaBBCc when crossed to a male of AAbbCc will produce an offspring of genotype AABbcc? 1/16 1/8 ½ ¼2. The traits studied by Mendel in his classical experiments showed: Epitasis Dominance and recessiveness Co-dominance Incomplete dominance3. If the genotypes of the parents were AABBccddeeFF and aabbCCDDEEff, what would be the genotype of the progeny? AABBccDDeeFf AaBbCCddEeFf AaBbCcDdEeFf aaBBccDDeeFF 4. When a heterozygous offspring is crossed with the homozygous recessive parent, the cross is called: Backcross Test-cross Cris-cross Reciprocal cross5. Polydactyly is a dominant trait, yet many individuals having single dominant alleles do not show any sign of polydactyly. This is known as: Incomplete penetrance Variable expressivity Incomplete dominance Co-dominance6. The phenotype of an organism is the result of: Genotype and environment interactions Cytoplasmic effects and nutrition Environmental changes and sexual dimorphism Mutations and nutrition7. The ABO blood groups in humans are controlled by the gene I. It has three alleles − IA, IB and i. Since there are three different alleles, six different genotypes are possible. How many phenotypes can occur? Three Two One Four8. Two different mutant strains of Drosophila give a black body color. When these mutants are crossed all progeny have wild type color. It means mutation is: Allelic Co‐dominant Non-allelic Epistatic9. If a plant with genotype AaBb is self-pollinated, where the A and B are not linked, then the probability of getting AABB genotype will be 1/8 ½ 1/16 ¼10. The suppression of the activity of one gene by another non-allelic gene is called: Hypostasis Pseudo-dominance Hypostasis Epistasis11. Which one of the following is the most suitable medium for the culture of Drosophila melanogaster? Moist bread Ripe banana Cow dung Agar-agar12. Cystic fibrosis is: An autosomal dominant disorder A sex chromosomal recessive disorder An autosomal recessive disorder A sex chromosomal dominant disorder13. In a genetic test the 9 : 7 ratio in the F2 generation represents: Epitasis Co-dominance Incomplete dominance Complementary interaction14. The possible type of gametes formed from genotype AABbCCDdEe will be: 4 32 8 1615. A small amount of lethal mutation always tends to remain in the population. It is due to: Negative selection Positive selection Mutation‐selection balance Frequency-dependent selectionYou have reached at the End of this Quiz.
