Biology Chapter Variation and Genetics/ Inheritance MCQs

If you are searching for the Biology Chapter Variation and Genetics/ Inheritance MCQs then you are in the right place. Variation & Genetics/Inheritance is also one of the major portions of the Biology MDCAT test syllabus. This portion comprises upon four chapters: Growth and Development, chromosomes and DNA, Cell Cycle and Variation, and Genetics. The main content of this chapter is Mendelian inheritance, gene control and expression, sex determination, genetic linkage, cell division, and genetic disorders. You will become able to explain different terms like locus, allele, gene, dominant, recessive, genotype, homozygous, heterozygous, mutation, epistasis, RH faction, polygenic, and many others. There will be different questions like the law of segregation and the law of independent assortment, monohybrid, dihybrid and crosses, and testcross. Students will also learn about sex linkage in humans, DNA replication, meselson, Stahl experiment and the mechanism of gene expression. So, check the important MCQs in the quiz form below.
