How do I solve Mendelian inheritance problems step by step?
Start from the definition: Mendelian inheritance refers to the rules describing how traits pass from parents to offspring through alleles. Then set up a Punnett square with parental gametes, then read the ratios. Follow that same order every time and most questions on this topic become mechanical rather than intimidating.
How to approach it step by step
Most learners lose marks on Mendelian inheritance not because the concept is hard, but because the steps get done out of order. This is exactly where a live 1:1 session helps: LetMeTeach solves one problem visually with you, then hands you a similar one and checks each step as you work, adapting the difficulty to how you answer.
Worked example
A Tt × Tt cross gives a 3:1 phenotypic ratio.
The mistake most learners make
Reading genotype ratios as if they were phenotype ratios.
