180-182 understand that genes exist in alternative forms called alleles which give rise to differences in inherited characteristics 184-186 understand the meaning of the terms: dominant, recessive, homozygous, heterozygous, phenotype, genotype 186-188 describe patterns of monohybrid inheritance using a genetic diagram 188-189 understand how to interpret family pedigrees 186-190 predict probabilities of outcomes from monohybrid crosses 190 understand that the sex of a person is controlled by one pair of chromosomes, XX in a female and XY in a male 190 describe the determination of the sex of offspring at fertilisation, using a genetic diagram 191-192 understand that division of a diploid cell by mitosis produces two which contain identical sets of chromosomes 190 understand that mitosis occurs during growth, repair, cloning and asexual reproduction 191 understand that division of a cell by meiosis produces four cells, each with half the number of chromosomes, and that this results in the formation of genetically different haploid gametes 190-192 understand that random fertilisation produces genetic variation of offspring
