Answer 1

Answer:

1. On solving the Punnett square of the heterozygous parents, it is evident that the chance of the first two offspring being black will be (3/4)*(3/4). This calculation is possible because the events are independent of each other
2. Every member of the F1 generation is heterozygous and the phenotype of the F1 generation expresses the dominant trait. Crossing two members of the F1 generation produces the second filial (F2) generation. Probability theory predicts that three quarters of the F2 generation will have the dominant allele's phenotype
3. Answer: Mendel proposed the law of inheritance of traits from the first generation to the next generation. Law of inheritance is made up of three laws: Law of segregation, law of independent assortment and law of dominance.
