  1. diploid
  2. monohybrid cross
  3. Unit character-traits controlled by factors (genes) which occur in pairs
  4. gene
  5. trait
  1. a There are alternative forms of genes called alleles; Ex. P- purple; p- white; There are two alleles for each trait; Ex. Pp; PpTT
  2. b unit of inherited information in DNA
  3. c mating of two organisms that differ in only one character
  4. d variation of a particular inherited character
  5. e having two homologous sets of chromosomes

5 Multiple choice questions

  1. genetic makeup of an organism; an organism's combination of alleles
  2. Probability of combination is product of individual probabilities
  3. the resulting offspring when the F1 plants fertilize or fertilize each other
  4. If the genes are located on separate chromosomes, the alleles of a pair segregate independently of other allele pairs during gamete formation
  5. egg or sperm sex cell that contains a single set of chromosomes, one from each homologous pair

5 True/False questions

  1. probabilityratio of a particular outcome


  2. haploidhaving two homologous sets of chromosomes


  3. Principle of SegregationThe dominant allele is expressed even when only 1 gene is present; written with CAPITAL letter; Ex. PP or Pp - purple; The recessive allele is expressed only when both genes are recessive; written with lower case letter; Ex. pp- white


  4. recessive alleledescriptive of an allele in a heterozygous individual that appears to be the only one affecting a trait


  5. First Filial (F1)the resulting offspring when the F1 plants fertilize or fertilize each other
