What is reproduction? - correct answer-the production a new generation of organisms from an existing generation (a life process that ensures the continued survival of a species. What is the goal of each species? - correct answer-to produce the max number of surviving offspring while using the least amount of energy (AKA reproductive effort) What is reproductive effort? - correct answer-total amount of energy used during reproduction What type of reproduction is energy efficient and in w...

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...
