Formulate the first law of Mendel. Why is this law called the law of dominance?

This law can be formulated as follows: when two homozygous organisms are crossed that belong to different clean lines and differ from each other in one pair of alternative characters, the entire first generation of hybrids (F1) will be uniform and will carry the trait of one of the parents.
Since all hybrids of the first generation are uniform, this phenomenon was called by K. Correns the first laws of Mendel, or the law of uniformity of hybrids of the first generation, as well as the rule of dominance.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
