WILF To be able to explain that

WILF To be able to explain that Variation between individuals may be either continuous or discontinuous and what this means Similarities and differences between individuals within a species may be the result of genetic factors, differences in environmental factors, or a combination of both.

From the previous lesson on mutation you should be able to: state what mutations are

From the previous lesson on mutation you should be able to: state what mutations are e xplain how mutations occur. In this lesson you should learn about the process of natural selection and how it e xplains why organisms evolve. . Success criteria: Describe the process of natural selection

Continuous and discontinuous variation Genes in population

Continuous and discontinuous variation Genes in population. Discontinuous Variation. The phenotypes we have consider so far have been due to two segregating alleles of single genes. This means that alternative phenotypes are clearly different.
