Genetic Disorders | Introduction

Genetic Disorders| Mendelian and Chromosomal Disorders XII STD - Bio-Zoology - Chapter:3 – Principles of Inheritance and Variation Genetic disorders may be grouped into two categories – Mendelian disorders and Chromosomal disorders. Mendelian disorders are mainly determined by alteration or mutation in the single gene. These disorders are transmitted to the offspring on the same lines as we have studied in the principle of inheritance. The pattern of inheritance of such Mendelian disorders can be traced in a family by the pedigree analysis. The chromosomal disorders are caused due to absence or excess or abnormal arrangement of one or more chromosomes. Failure of segregation of chromatids during cell division cycle results in the gain or loss of a chromosome(s), called aneuploidy. genetic disorders class 12, genetic disorders class 12 in English, genetic disorders class 12 neet, Biology Genetics Class 12, Genetic Disorders Neet/Aiims/Jipmer Syllabus, inherited genetic disorders, GENETIC DISORDERS IN English CLASS 12| CBSE/ TNSCERT , Principles of inheritance and Variations, mendelian disorders class 12, Chromosomal Disorder #NeetBiologyExpert #geneticsclass12 #class12biology #class12genetics #geneticdisorders #geneticdiseases #geneticmutations #mutations #mutationsclass12 #neetpreparation #aiims #jipmer #geneticdisorders #genetic_disorders #genetics #Heredity #Genetics #Biology #Education
