Fundamentals of Genetics Welcome to your Fundamentals of Genetics 1. What is the effect of sexual reproduction? Offspring is more vigorous Offspring is like the parents Offspring is weak Offspring is diseased2. Pea plants were used in Mendel's experiments because They were cost effective They were easily available All of the above They had contrasting characters3. The geometrical device that helps to find out all the possible combinations of male and female gametes is known as Punnett square Bateson square Mendel square Crick square4. Which term represents a pair of contrasting characters? Heterozygous Homozygous Allelomorphs Codominant genes5. Chromosomal aberrations are caused by Change in the arrangement or the position of genes Change in the number of chromosomes Change in the structure of the gene Change in both the number and arrangement of genes6. A cross was made between tall and dwarf plants. In F1 generation, all plants were tall, when the F1 plants were self pollinated, the tall and dwarf plants appeared in 3:1 ratio in F2 generation. This phenomenon is known as Hybridisation Segregation Crossing Over Dominance7. Which of the following is true about the "Law of Segregation"? Segregation of factors is due to the segregation of chromosomes during meiosis Alleles separate from each other during gametogenesis Law of segregation is the law of purity of gametes All of the above8. When an individual has both the genes of a contrasting character, it is said to be Phenotype Genotype Homozygous Heterozygous9. Genetics is a branch of Biology dealing with Heredity in living beings None of these Variation in living beings Both Heredity and Variation10. The genotypic ratio of a monohybrid cross is 2:1:1 1:2:1 9:3:3:1 3:111. The 9:3:3:1 dihybrid ratio is due to Crossing over Segregation Homologous pairing Independent assortment12. Which one of the following is a phenotypic monohybrid ratio in F2 generation? 3:1 1:3 2:2 1:2:113. When two individuals differing in atleast one character are crossed, the process is known as Hybridisation Pedigree None Selection14. DNA structure was discovered by Watson and Crick H.G.Khurana Lamarck Mendel15. The smallest unit of genetic material which produces a phenotypic effect on mutation is Muton Recon Gene Nucleic acid16. An exception to Mendel's law is Linkage Independent assortment Purity of gametes Dominance17. The alternative form of a gene is Dominant character Recessive character Alternate type Allele18. The crossing of F1 to any of the parent is known as Test cross F1 cross All of the above Back cross19. Mendel's findings were rediscovered by Tschermark Correns De Vries All the above20. Who among the following is called the father of Genetics? Mendel Watson and Crick Darwin Lamarck21 out of 20Please fill in the comment box below.
