Document Summary

Cross between the alleles present in 20 hypothetical gametes (10 sperm and 10 eggs). The results may also be represented as probability values. A record of what major events occur in the life cycle of a gamete: two gametes form a germinated zygote, zygotes develop into juvenile offspring, and offspring reach sexual maturity and start producing new generation of gametes. If the allele frequencies change over a single generation, then evolution has occurred. The hardy-weinberg principle is a simple and unlikely model for a population of the same species. The principles will only be seen in a population of the same species if the following assumptions are met: Diploid population all individuals contain diploids in their genotypes. Sexual reproduction all individuals reproduce through sexual reproduction. No evolution no evolutionary mechanisms are acting upon the population. All individuals survive to reproduce sexual maturity is reached by all individuals. Mating is random individuals mate indiscriminately with other individuals.
