If random chromosome loss occurs this could result in the haploidisation of the initial diploid. Such a complete parasexual cycle of reproduction is not likely to occur in flowering plants; but the extent to which it occurs in wide crosses could prove of considerable importance to the plant ...

Insects are the chief pollinators and it has-been noted that the evolution of flowering plant has gone hand-in-hand with the evolution of the insects. Insects helping in pollination are bees, flies, beetles and moths. Of these the first three are diurnal visiting flowers which opens in day ...

In years in which self- pollination is frequent it may pay plants to not invest in seeds that make little contribution to fitness, but rather Sexual conflict in plants SCH Barrett save resources for future reproduction, hence increasing lifetime fitness. This could be important in N. triandrus...
This is the process of sexual reproduction. Sexual reproduction One of the characteristics of all living organisms is their ability to reproduce according to genetic instructions within the organisms themselves. In chapter 10, we explored the world of asexual reproduction, as seen in prokaryotes and ...

Life-history theory revolves around the idea that various activities, such as growth, maintenance, and reproduction, compete for limited resources. Hence, current reproduction may lead to a reduction in growth and survival, and consequently a reduction i
