Selective Advantage Every individual within a species population has the?potential to reproduce?and have offspring In reality, however, there are many?environmental factors?that?prevent?ever...
Natural Selection Every individual within a species population has the?potential to reproduce?and have offspring which contribute to population growth If all the offspring of every individua...
Natural Selection: Hardy-Weinberg Principle The Hardy-Weinberg principle states that if certain conditions are met then the?allele frequencies of a gene within a population will not change f...
Gene Pools & Allele Frequency Gene pools The?phenotype?of an organism is dependent on its?genotype?and the environmental influence on the organism Members of the?same species?will have t...
Predicting Inheritance: Chi-squared Test The?difference between expected and observed results?in experiments can be statistically significant or insignificant (happened by chance) If the dif...
Apparatus & Techniques: Investigating Genetic Ratios Known information about genotypes, phenotypes and the process of meiosis can be used to make?predictions?about the phenotypes of offs...
Predicting Inheritance: Test Crosses A test cross can be used to?deduce the?genotype?of an unknown individual that is expressing a dominant?phenotype The individual in question is crossed wi...
Dihybrid Crosses Monohybrid crosses look at how the alleles of one gene transfer across generations Dihybrid crosses look at how the alleles of?two genes?transfer across generations The gene...
Monohybrid Crosses Monohybrid inheritance looks at how the?alleles for a single gene are passed on from one generation to the next Known information about the genotypes, phenotypes and the p...
