HSC Biology Module 5 Reproduction Reproductive success The ability to produce fertile offspring that survive to reproductive maturity and produce offspring of their own. Biological fitness the measure of an individual's reproductive success. It is calculated as the average contribution to the gene pool made by a certain genotype within a population and the relative likelihood that these alleles will be represented in future generation. Sexual reproduction It involves the meet...
