Answer:
A. Two different forms a plant can have
Explanation:
Higher plants, lower plants (mosses) and ferns undergo a life cycle called ALTERNATION OF GENERATIONS. In this life cycle, they switch between a haplontic and diplontic forms of life.
The haplontic (haploid) life form which produces haploid (n) gametes is called GAMETOPHYTE while the diplontic (diploid) life form which produces the spores that germinates is called SPOROPHYTE. Hence, sporophyte and gametophyte are two different forms a plant can have.

Answer:
This is because crossing over occurs between two homologous chromosomes. It involves an exchange of segments of their arms of the two chromosomes during Metaphase I of meiosis. Genes on the different chromosomes are, therefore, more likely to be crossed over than genes on the same chromosome. In addition, because sections of the arms are exchanged, genes that are close to each other on the same chromosome are more likely to be exchanged together (these are called linked genes) than genes that are far apart on the same chromosome.
