Answer: The two types of gametes are possible for when they are following genes that are on the same chromosomes. If they are crossing over, it does not occur, the products are known as Parental Gametes. If they are crossing over, the products are Recombinant Gametes. It is usually the simple matter that determine which of these gametes are recombinant gametes.
The difference between these two genes, is that are far apart and the frequency of recombination of genes is fifty percent. These genes that are closely located on the chromosome exhibit only have a few cross overs. The gametes that have recombined chromosomes, are known as Recombinant Gametes while the Parent Gametes are carrying on non-recombinant chromosomes.

Answer:
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
Explanation:
Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.
When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.
