Genetics and Probability Concepts

Miss Co Tran explains genetic concepts such as alleles, dominant and recessive traits, and the use of Punnett squares to determine genetic probabilities. She discusses homozygous and heterozygous alleles and uses examples to illustrate how traits are inherited. The video aims to clarify students' confusion about Punnett squares and enhance their understanding of genetic inheritance.
