• What did Mendel's experiments on the other six traits yield?

  The same trend as the initial experiment.
• What are alleles?

  Alleles are alternative forms of genes that regulate the traits of an organism.
• Where are alleles found?

  Alleles are found on homologous chromosomes at a particular locus.
• How are alleles inherited?

  Alleles are inherited in pairs, with one copy from each parent.
• What happens during meiosis regarding alleles?

  During meiosis, homologous chromosomes with sister chromatids separate, resulting in one allele for each trait in a gamete.
• What does Mendel's Law of Segregation explain?

  Mendel's Law of Segregation explains why there is only one allele for each trait in a gamete.
• What are the two types of alleles?

  Dominant and recessive alleles.
• How is a dominant allele represented?

  A dominant allele is represented by an uppercase letter.
• How is a recessive allele represented?

  A recessive allele is represented by a lowercase letter.
• What are the alleles for yellow and green seed color in peas?

  The allele for yellow seed is Y (dominant) and for green seed is y (recessive).
• What does it mean if an organism is homozygous for a trait?

  It means the organism has two identical alleles for that trait.
• What is the genotype for an organism that is homozygous dominant for yellow color?

  The genotype would be YY.
• What is the genotype for an organism that is homozygous recessive for green color?

  The genotype would be yy.
• What are pure breed or true breed parents?

  Parents with identical alleles for a trait.
• What does it mean if an organism is heterozygous for a trait?

  It means the organism has two different alleles for that trait.
• What would be the genotype for an organism with alleles Tt?

  The organism would be heterozygous for that trait.
• What trait would be expressed in an organism with genotype Tt?

  The trait expressed would be yellow because it is the dominant trait.
• How long did Mendel's experiment take to finish?

  Seven years.
• What did Mendel suggest about the F generation?

  Mendel suggested that the F generation has unit determiners, one for the dominant trait and one for the recessive trait.
• What did Sutton name the unit determiners suggested by Mendel?

  Sutton named them genes.
• What are the alleles for flower position in Mendel's experiment?


  A = axial and a = terminal.
• What is the genotype for an axial flower position?

  The genotype would be AA.
• What is the genotype for a terminal flower position?

  The genotype would be aa.
• What are genotypes and phenotypes?

  Genotypes describe the genes of an organism, while phenotypes describe the physical characteristics of a trait.
