QUESTIONS LIST:

• genes : factors that determine traits.
• hybrid : offspring of parents that have different forms of a trait.
• phenotype : the way an organism looks and behaves (tall or short).
• gregor mendel : an austrian monk, discovered important facts about heredity using garden peas.
• law of segregation : every organism has two alleles of each gene and when gametes are produced the alleles separate.
• heredity : the passing on of characteristics from parents to offspring.
• alleles : different forms of genes, such as genes for height can either produce genes for tall plants or genes for short plants.
• garden peas : produce male and female sex cells called gametes.
• fertilization : occurs when the male and female reproductive cells join forming a zygote.
• reginald punnett : came up with the punnett squares to predict the proportions of possible genotypes in offspring.
• genetics : the scientific study of heredity.
• meiosis : a type of cell division that produces four cells, each with half the number of chromosomes as the parent cell.
