How to determine genotype

12th grade students preparing for the high school graduation exam.

In Topic 6 - Determining the genotype of parents from the phenotypic ratio of offspring, Mr. Vo Thanh Binh, a teacher at Le Hong Phong High School for the Gifted (Ho Chi Minh City), introduced students to a method for quickly determining the genotype in a two-trait cross, where genes are located on autosomal chromosomes, one gene controls one trait, and the dominant gene is completely dominant.

According to Mr. Binh, exercises on the laws of heredity are always the most difficult and have the highest number of points in the exam. When doing exercises in this section, one piece of information that must always be determined is the genotype of the two organisms being crossed and the laws of heredity governing the genes being considered.
