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..

One of the following inhibits the secretion of gastric juices Enterogastrone Secretin C C K Gastrin 2. Vit. D is synthesised in presence of sunlight in Skin Bone Liver Spleen 3. Antipellagra factor is B1 B2 B5 B12 4. The sphincter which separates oesophagus from stomach is called: Pyloric sphinctor Cardiac sphinctor Sphinctor of Oddi Anat sphincter 5. Which are enzymes of gastric gland Trypsin and rennin Pepsin and rennin Lipase and trypsin Vessopressin and lipase 6. Yeast is source of Vitamin A Vitamin D Vitamin C Riboflavin 7. Scurvy disease is produced in the deficiency of : Vitamin C Vitamin E Vitamin K Vitamin A 8. Mode of digestion in 'Hydra' is Intracellular Extracellular Both of these None of these 9. Which combination is incorrect Niacin-Pellagra Thiamin-Beriberi Vitamin K-Sterility Vitamin D-Rickets 10.

Developmental Biology MCQs Part 1 10:18:00 AM Posted by AEI Online Tutor No Comments Developmental Biology MCQs Part 1 1. The following is a class of proteins that is part of the complex that regulates the central events of the cell cycle. cyclins caspases tublins none of these 2. We assay the activity of a particular MAP kinase in two different cell types and find that activity is present in one cell but not the other. Possible reason for this differential activity includes: diffential MAP kinase gene transcription diffrential mRNA processing of the MAP kinase transcript diffential translation of the MAP kinase transcript all of these 3. Tumor suppressors include genes whose normal functions are: cell adhesion activators of apoptosis c3 d3 4. If we transplant an amphibian optic cup subjacent to head ectoderm, a lens forms from the ectoderm. However of we transplant the optic cup subjacent to trunk ectoderm, no lens forms. The diffential response by the head and trunk actoderm could be due to diffential expression of extracellular matrix intiator capassees receptor actin 5. "Death receptors" are likely to activate paracrine signals ubiquitin cyclin dependent kinase inhibitors(CKIs) initiator caspases 6. The best commercial sponges are found in the warm waters of: Carabian sea Mediterranean sea Red sea none of these 7. Which one of the following structures determines the type of tooth to be formed? Ectoderm Mesoderm Ectomesenchyme Endoderm 8. Simple binary fission is found in Paramecium Sponge Euglena Amoeba 9. Paramecium and Planaria exhibit Simple binary fission Transverse binary fission Longitudinal binary fission Oblique binary fission 10. Which of the following animal show Longitudinal binary fission Euglena and Vorticella Opalina and Monocystis Volvox and Chlamydomonas Entamoeba and Trypanosoma Score = Correct answers: Developmental Biology MCQs Part => 1..
