Question
Chapter 36, Problem 14TYK
Summary Introduction
To review:
The reasons for which the hybrid parent and fertile polyploid offspring are considered as new species.
Introduction:
Polyploidy is the condition in which there are more than one set of chromosomes present in the organism. The causes of polyploidy can be non-disjunction of homologous chromosomes, failure of cytokinesis, or hybridization. Hybridization is the mating of organisms that belong to two different species and produces sterile or in some rare cases fertile offspring.

Compare and contrast the alternation of generations in pines and angiosperms. This must be very detailed and include all major structures and process involves. Be sure to include when the plants are haploid or diploid. You can use a list as long as order is clear. Be sure to clearly write out structure and processes and indicate which things are the same and which are different.
An alternation of generation life cycle in plants is advantageous because:
each generation is morphologically similar.
it protects reproductive structures.
the gametes fuse in open water.
it is haploid-dominant.
Draw a simple diagram illustrating alternation of generations in plants, including the sporophyte and gametophyte generations, spores, gametes (eggs and sperm), meiosis, and fertilization. Be sure to indicate whether each generation or kind of cell is haploid or diploid.
