  1. 2. of phases in Meiosis Eight
  2. 3. Mendel The Father of Genetics
  3. 4. of Independent Assortment This law states that a random distribution of alleles occurs during gamete formation.
  4. 6. The occurrence of one or more extra sets of all chromosomes in an organism.
  5. 7. Maps These show the sequence of genes on a chromosome and can be created by using crossover data.
  6. 9. Chromosome pair that make a pair, containing one chromosome from each parent.
  7. 10. a cell with n number of chromosomes.
  8. 11. Cross A cross that involves hybrids for a single trait.
  9. 12. II Chromosomes condense, spindles form in each new cell, and spindle fibers attach to chromosomes in this process of Meiosis.
  10. 15. II Spindles break down and four nuclei form around chromosomes in this process of Meiosis.

  12. 19. The observable characteristic or outward expression of an allele pair.
  13. 20. The organism's allele pairs are called this.
  14. 22. The study of the science of heredity.
  15. 24. A cell that contains 2n number of chromosomes.
  16. 26. II Centromeres split and sister chromatids separate and move to opposite poles in this process of Meiosis.
  17. 28. Squares These make it easier to keep track of possible genotypes involved in a cross.
