Mendel’s first law (the law of uniformity of hybrids of the first generation) says that when organisms differing in allelic characters are crossed, in the first generation of hybrids only one of them appears – dominant, and the alternative, recessive, remains hidden.
Mendel’s second law (the law of splitting) states that when two hybrids of the first generation are crossed between themselves in the second generation, both signs of the initial parental forms appear in a certain ratio.
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.
