CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Mendel called the visible form the dominant trait and the hidden form the recessive trait. In the second generation, after plants were allowed to self-fertilize (pollinate themselves), the hidden form of the trait reappeared in a minority of the plants.

Detailed explanation-2: -He found that some traits are dominant and would always be expressed in a first generation cross, while others are recessive and would not appear in this generation. However, these recessive traits re-appear in the next generation if these first-generation plants self-fertilise.

Detailed explanation-3: -The results of Mendel’s second set of experiments led to his second law. This is the law of independent assortment. It states that factors controlling different characteristics are inherited independently of each other.

Detailed explanation-4: -The second generation that came from the first-generation self-fertilizing had the recessive trait reappear in about 1 in 4 of the plants, with there being a 3:1 ratio for plants that showed the dominant trait for every plant that showed the recessive trait.

Detailed explanation-5: -The trait expressing itself in the hybrid is the dominant one. This experiment proves Mendel’s first law of inheritance. It states that when a pair of contrasting factors are brought in a hybrid, one factor inhibits the appearance of the other, one which inhibits is the dominant one and which is inhibited is recessive.
