Asexual reproduction in protozoa and invertebrates

Journal of Theoretical Biology, 1982
Abstract A model which defines fitness in terms of rate of clone increase, and which assumes constant mortality, predicts that more smaller offspring should be produced in conditions which are good for individual growth. Evidence from the Protozoa, freshwater flatworms and anthozoan cnidarians support this prediction. Fitness is maximized by budding

Growth and asexual reproduction

1971
Growth is increase in biomass. In protozoa and protophyta growth in an organism to a critical size is followed by division into independent daughter organisms. Thus growth is also growth in the number of organisms in a colony. If an inoculum of micro-organisms is placed in a culture medium and sampled at intervals the growth curve of the culture can be

Asexual Reproduction or Apomixis

1964
Reproduction is asexual (apomictic) when it occurs without recombination. Apomixis (Greek apo = without, mixis = mingling) is the general term for it. The simplest case is found in unicellular plants and animals where there is doubling of cytoplasmic contents and replication of genetic material followed by division of the cell into two parts.

Sexual Reproduction in Fungi

1980
sexual reproduction in fungi is characterised by a wide variety of mechanisms and controlling factors. The underlying feature, typical of all sexually reproducing organisms, is a fusion event involving two compatible nuclei. However, fungi are mostly haploid, and meiotic division occurs after nuclear fusion.
