Genotype formula

Grade 12 students prepare to take the high school graduation exam

In topic 3 - Formula for calculating the number of genotypes of triploids and triploids, teacher Vo Thanh Binh, teacher at Le Hong Phong High School for the Gifted (HCMC), guides students on how to build a formula to determine the maximum number of genotypes that can be found in triploid and triploid mutants.

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

This content is broadcast on the following platforms: website thanhnien.vn , Facebook fanpage and YouTube channel of Thanh Nien Newspaper.
