Fundamentals of Genetics Welcome to your Fundamentals of Genetics 1. The smallest unit of genetic material which produces a phenotypic effect on mutation is Recon Muton Gene Nucleic acid2. When two individuals differing in atleast one character are crossed, the process is known as Pedigree Selection Hybridisation None3. Pea plants were used in Mendel's experiments because They had contrasting characters All of the above They were easily available They were cost effective4. Mendel's findings were rediscovered by All the above De Vries Tschermark Correns5. The genotypic ratio of a monohybrid cross is 9:3:3:1 3:1 1:2:1 2:1:16. Which term represents a pair of contrasting characters? Allelomorphs Codominant genes Heterozygous Homozygous7. The geometrical device that helps to find out all the possible combinations of male and female gametes is known as Mendel square Crick square Punnett square Bateson square8. Chromosomal aberrations are caused by Change in both the number and arrangement of genes Change in the structure of the gene Change in the number of chromosomes Change in the arrangement or the position of genes9. The 9:3:3:1 dihybrid ratio is due to Segregation Independent assortment Homologous pairing Crossing over10. An exception to Mendel's law is Linkage Independent assortment Dominance Purity of gametes11. Genetics is a branch of Biology dealing with None of these Both Heredity and Variation Variation in living beings Heredity in living beings12. Which one of the following is a phenotypic monohybrid ratio in F2 generation? 2:2 1:3 3:1 1:2:113. Which of the following is true about the "Law of Segregation"? All of the above 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 gametes14. DNA structure was discovered by H.G.Khurana Lamarck Watson and Crick Mendel15. 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 Dominance16. The alternative form of a gene is Alternate type Recessive character Allele Dominant character17. The crossing of F1 to any of the parent is known as F1 cross Back cross Test cross All of the above18. What is the effect of sexual reproduction? Offspring is weak Offspring is diseased Offspring is more vigorous Offspring is like the parents19. Who among the following is called the father of Genetics? Mendel Watson and Crick Lamarck Darwin20. When an individual has both the genes of a contrasting character, it is said to be Heterozygous Phenotype Homozygous Genotype21 out of 20Please fill in the comment box below.
