Fundamentals of tracking genes

• Monohybrid inheritance is the tracking inheritance of one gene
• Genotype is the allele an individual has for a trait
• Phenotype is the physical expression of a trait
• Dominant is the allele the to always expressed if present
• heterozygous is where it contains two different alleles in the genotype
• Homozygous is the genotype with two of the same alleles
• mention heterozygous genotype in pedigree chart question
• Parental generation off spring = F1 generation
• Test crosses is used to find out what genotype a dominant phenotype individuals is
•  A Pedigree chart is a diagram that allows you to follow the inheritance of genetic variation across generations, and can be used to determine the genotype and phenotype of individuals in the chart.
• Punnet squares/expected phenotype ratios are just a prediction
• Mention reproduction rate, and high proportion of offsprings
