sexual reproduction
fertilization
haploid
diploid
chromosomes
meiosis
gametes
genetic variation
inheritance
chromosome
phenotype
genotype
allele
gene
homozygous
heterozygous

independent assortment
Address the Learning Objective Below:
Sexual reproduction (Define sexual reproduction as the process involving the fusion of haploid gametes to form a diploid
offspring and the production of genetically dissimilar offspring
Meiosis
 Define meiosis as reduction division in which the chromosome number is halved from diploid to haploid (details of
stages are not required)
 State that gametes are the result of meiosis
 State that meiosis results in genetic variation so the cells produced are not all genetically identical
Genetics- Monohybrid inheritance
 A gene may be copied and passed on to the next generation
 Describe the inheritance of sex in humans (XX and XY chromosome)
 Calculate and predict the results of monohybrid crosses using Punnett squares
 Explain codominance by reference to the inheritance of ABO blood groups, phenotypes, A, B, AB and O blood groups
and genotypes IA, IB, and IO
 Describe how some alleles are on the X and Y sex chromosomes
 Understand how to use pedigree charts to make predictions about inheritance of a specific trait.
 Be able to make a pedigree chart showing a gene/allele being pass from one generation to the next.
 Calculate and predict the genotypic and phenotypic ratio of offspring of dihybrid crosses involving unlinked autosomal genes.

