Lab Report_ Environmental Control of Sex Determination

Introduction Ceratopteris richardii, known as a C-fern has a lifecycle referred to as alteration of generations, which consist of neither haploid nor diploid dominant. C-ferns are homospours plants which are important in that they can produce hermaphrioditic gametophytes in order to be able to self fertilize.

These spores then undergo mitosis to…
