At the time of fertilization in humans, two gametes, each containing a unique combination of alleles, fuse to form a diploid offspring. if you ignore crossing over, a single person can produce gametes with roughly how many different chromosome combinations

Ican not answer this question since it does not have enough information

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process.
