Inheritance Biology MCQs Part 1 9:34:00 PM Posted by AEI Online Tutor No Comments - MCQs part - 1. The resemblance of individuals to their progenitors is called heredity genetics evolution none of these 2. Mendel formulated some laws which are known as Laws of germplasm Laws of origin of species Laws of recapitulation Laws of inheritance 3. Which of the following is dominant character according to Mendel? Dwarf plant and yellow fruit Terminal fruit and wrinkled seed White testa and yellow pericarp Green coloured pod and rounded seed 4. The alleles are a pair of genes governing a specific character such as tallness or dwarfness multiple forms of genes genes governing eye characters genes present in allosomes 5. When a true breeding pea plant that has yellow seeds is pollinated by a plant that has green seeds, all the F1 plants have yellow seeds. This means that the allele for yellow is heterozygous dominant recessive lethal 6. In Mendel’s experiment, nature of seed coat, flower colour, position of flower, pod colour, stem height, etc. are referred to as alleles genotypes phenotypes all of above 7. An organism with two identical alleles for a given trait is homozygous segregating dominant a hermaphrodite 8. Organisms phenotypically similar but genotypically different are said to be heterozygous monozygous multizygous homozygous 9. Which of the following cross will give recessive progeny in F1 generation ? TT × tt Tt × TT tt × tt TT × TT 10. When Mendel crossed true breeding whiteflowered strain of peas with a true breeding red-flowered strain, individuals in the F2 represented [DPMT 1976] white-flowered plants red-flowered plants red-flowered and white-flowered plants in the ratio 3 : 1 red and white-flowered individuals in the ratio 1 : 1 Score = Correct answers: Inheritance Biology MCQs Parts => 1..
