Textbook Question
Chapter 16, Problem 18P
In land plants, there is an alternation of generations between a haploid gametophyte generation and a diploid sporophytic generation. Both generations are typically multicellular and may be free
How would you conduct a screen to identify genes required for female gametophyte development in Arabidopsis?
How would you conduct a screen to identify genes required for male gametophyte development?

While conducting a plant diversity survey in a temperate rainforest in Washington state, you come across a number of individuals of a low-lying plant species. These plants spread over the surface of moist groun and have numerous small stems that have tiny leaflets. They have root-like structures but do NOT have roots. Back at the lab, tests indicate that the majority of the plant material is haploid. The plant you discovered is likely most closely related to
-a moss.
-complex streptophyte algae.
-a daisy
-a conifer
-a lycophyte
In moss, the genes A and B are expressed only in the gametophyte. A sporophyte of genotype A/a ; B/b is allowed to produce gametophytes.a. What proportion of the gametophytes will be A ; B?b. If fertilization is random, what proportion of sporophytes in the next generation will be A/a ; B/b?
Which of the following pairs of plant structure has the haploid number ofchromosomes?
A. Megaspore mother cell and antipodal cells
B. Egg cell and antipodal cells
C. Egg cell and endosperms
D. Microspore mother cell and antipodal cells
