Polydactyly is a dominant trait, yet many individuals having single dominant alleles do not show any sign of polydactyly. This is known as: Co-dominance Variable expressivity Incomplete penetrance Incomplete dominance2. If the genotypes of the parents were AABBccddeeFF and aabbCCDDEEff, what would be the genotype of the progeny? AaBbCcDdEeFf AaBbCCddEeFf AABBccDDeeFf aaBBccDDeeFF 3. When a heterozygous offspring is crossed with the homozygous recessive parent, the cross is called: Backcross Reciprocal cross Test-cross Cris-cross4. The possible type of gametes formed from genotype AABbCCDdEe will be: 16 4 8 325. The suppression of the activity of one gene by another non-allelic gene is called: Hypostasis Pseudo-dominance Epistasis Hypostasis6. Cystic fibrosis is: A sex chromosomal dominant disorder An autosomal dominant disorder A sex chromosomal recessive disorder An autosomal recessive disorder7. 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 ½ 1/16 ¼ 1/88. 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: Co‐dominant Epistatic Allelic Non-allelic9. In a genetic test the 9 : 7 ratio in the F2 generation represents: Epitasis Incomplete dominance Co-dominance Complementary interaction10. 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 One Two Four11. The traits studied by Mendel in his classical experiments showed: Incomplete dominance Co-dominance Dominance and recessiveness Epitasis12. Which one of the following is the most suitable medium for the culture of Drosophila melanogaster? Ripe banana Moist bread Cow dung Agar-agar13. The phenotype of an organism is the result of: Genotype and environment interactions Mutations and nutrition Environmental changes and sexual dimorphism Cytoplasmic effects and nutrition14. 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? ¼ 1/8 1/16 ½15. A small amount of lethal mutation always tends to remain in the population. It is due to: Mutation‐selection balance Positive selection Frequency-dependent selection Negative selectionYou have reached at the End of this Quiz.
