C04 Inheritance and Variation

What’s on the Specification

B4.1	Know and understand the nucleus as a site of genetic material in eukaryotic cells.
B4.2	Know and understand the following genetic terms: Gene Allele Dominant Recessive Heterozygous Homozygous Phenotype Genotype Chromosome Autosome.
B4.3	Monohybrid crosses: Use and interpret genetic data and diagrams involving monohybrid (single gene) crosses. Use and interpret family trees/pedigrees and express outcomes as ratios, numbers, probabilities or percentages. Understand the concept of inherited conditions. Know that most phenotypes are the result of multiple genes and only some result from single gene inheritance.
B7.2	Sources of variation: Understand that variation can be genetic/inherited, resulting in a range of phenotypes. Understand that variation can also be environmental, which affects a range of phenotypes.
