Formula for calculating genotype

12th grade students are preparing to take the high school graduation exam.

In Topic 3 - Formulas for Calculating the Number of Genotype Types in Trisomy and Triploidy, Mr. Vo Thanh Binh, a teacher at Le Hong Phong High School for the Gifted (Ho Chi Minh City), guides students on how to construct formulas to determine the maximum number of genotype types that can be found in triploid and triploid mutations.

The formula is based on each pair of homologous chromosomes. From there, depending on the question's requirements, students determine the number of types of trisomy (one pair of chromosomes has 3 chromosomes, other pairs have 2) or triploidy (all pairs of chromosomes have 3 chromosomes). This is a difficult topic and frequently appears in recent years' high school graduation exams. In addition, Mr. Binh spent time reviewing related questions from recent years' exams.
