Explore how homologous chromosomes pair in humans, with 23 chromosome pairs, and how chromatids duplicate into sister chromatids, encoding genes and alleles in DNA.
Explore Mendel's genetics terminology, including genes, factors, alleles, and dominant versus recessive traits, and describe how genotype and phenotype relate in monohybrid and dihybrid pea plant studies.
Explore Mendel's life and his three laws of inheritance—dominance, segregation, and independent assortment—through mono- and dihybrid pea crosses and Punnett square analysis.
Explore deviations from Mendel's laws of dominance and independent assortment, including incomplete dominance, co-dominance, multiple alleles, and polygenic traits, with practical examples like HBO blood group.
Explore deviations from the law of independent assortment caused by linkage of genes on chromosomes, as Morgan's drosophila work shows genes near each other inherit together.
Explore incomplete dominance, where heterozygotes show an intermediate phenotype—pink from red and white—contrasting with Mendel's law and illustrating the 1:2:1 phenotype ratio in F1.
Explore co-dominance as a deviation from Mendel's laws, where both alleles are equally expressed in heterozygotes, illustrated by the MN blood group where M and N markers appear on RBCs.
Explore polygenic inheritance and how multiple genes shape complex traits like skin color, height, and eye color, with environment influencing outcomes.
Explore multiple alleles and inheritance in the ABO blood group system, detailing how I_A, I_B, and i alleles yield A, B, AB, or O types with dominance and universal donors/recipients.
Understand pleiotropy, where one gene affects multiple traits. Explore sickle cell anemia and PKU as key examples of how single mutations alter hemoglobin and metabolic enzymes across phenotypes.
Explore how epigenetics links environment, diet, aging to gene activity through methylation and acetylation of histone proteins, regulating DNA accessibility and transcription.
Explore test and back cross concepts through a bonus quiz, covering polygenic inheritance with three genes yielding 64 possible allele combinations and Mendel's true-breeding and monohybrid crosses in plants.
Explore test crosses and back crosses to determine unknown genotypes in mono-hybrid and dihybrid crosses, analyze phenotype ratios, and apply crossing concepts to breeding scenarios.
In this course, students will imbibe knowledge about Principles of Inheritance and would be able to solve the questions based on different crosses (discussed below).
This course is designed by keeping in mind the difficulty level in understanding the various concepts by students. The course commences with basic topics like difference between homologous and non-homologous chromosomes, chromatids, sister and non-sister chromatids, Gene and Factors, DNA, Nucleosomes, solenoid structure, human chromosomal makeup, concept of Alleles, Genotype and Phenotype, Genotypic ratio and Phenotypic ratio, Dominant and Recessive, Monohybrid and Dihybrid cross, Punnet Square, F1, F2 generation etc to advanced concepts like Mendelian genetics, deviation from Mendel's Inheritance laws, brief discussion on Morgan experiment, chromosomal theory of inheritance, detailed explanation with examples on- 3 laws of inheritance, Incomplete dominance, Codominance, Polygenic Inheritance, Multiple Alleles, Pleiotropy, Epigenetics, Test cross and Back cross, and finally how to solve questions based on these crosses etc.
After completing this course you will be able to apply these concepts practically for understanding the inheritance pattern in future generations. Also, you will find the reality that twins are not 100% identical, Why?,... Also why in siblings one grows taller in height while other one remains short? or Why there are so many varieties of skin tone color present in entire world population? or why a mutation in one particular functional gene alters the function at some other part of body?...... you need to finish this course for all the answers.
Not only this, You are getting one bonus quiz too at the end of completing this course. Finishing this bonus video will give you full understanding of, how you can find the genotype of any unknown parent/individual/may be yours too,by just looking at the ratios of offspring and other interesting information.
So, join and enroll for this course today and get most out of it.
