Dihybrid Cross in Genetics – Simple and Practical Explanation

Dihybrid Cross

Genetics is the study of genes, heredity, and variation in living organisms. It explores how traits are passed from parents to offspring through genetic material like DNA. Understanding genetics helps unravel the mechanisms behind inherited characteristics, diseases, and the diversity of life forms on Earth. Genetic crosses are experimental tools used to study inheritance patterns […]

Difference Between Homozygous and Heterozygous Individuals

homozygous heterozygous

Have you ever noticed how some diseases pass down generations even when parents don’t have it? Many individuals with thalassemia, for example, have perfectly healthy parents. The opposite also holds: parents with a trait don’t always pass it down to their children. This curious case of genetics comes down to a power struggle between the […]

How to Calculate Punnett Square for Dihybrid Cross

Make punnett square

  A significant component of genetics is how children inherit genes from their parents. If you recall my lectures, children do not inherit all the traits of their parents. Depending on whether the parents are homozygous or heterozygous, traits tend to skip generations. While it sounds complicated to understand gene inheritance, geneticists use Punnett squares […]

What are Genotype and Phenotype – Key Differences

The world knows James Watson as the legendary scientist who unlocked the secrets of the DNA molecule. He once said, “We used to think that our fate was in our stars, but now we know that, in large measure, our fate is in our genes.” While our genes heavily affect our fate, have you ever […]

What is difference between Monohybrid and Dihybrid Crosses

The titled question is one of the basics and most asked questions during the class. The same happened to me when a student asked to differentiate between monohybrid and dihybrid cross. I always answer such a question in two steps i.e., first I give a quick brief, then I explain every concept in a deeper […]
