Question
Chapter 19, Problem 2WIO
Summary Introduction
To analyze:
The alternation of generations common to all plants. Is there any variation among the gametes, if DNA of all the gametes produced by one gametophyte is analyzed?
Concept Introduction:
The alternation of generation includes the haploid and diploid gametes formation by mitotic division by the gametophyte. The DNA describes ploidy of the cells.
