Across
  1. 3. The diploid product of the union of haploid gametes in conception; a fertilized egg.
  2. 5. A mutational loss of a nucleotide from a gene.
  3. 7. An aberration in chromosome structure resulting from an error in meiosis or from mutagens; reattachment in a reverse orientation of a chromosomal fragment to the chromosome from which the fragment originated.
  4. 8. Replicated forms of a chromosome joined together by the centromere and eventually separated during mitosis or meiosis
  5. 11. A cell containing only one set of chromosomes (n).
  6. 13. A genetic mutation of the cell causing rapid growth passing through the G0 phase.
  7. 15. A two-stage type of cell division in sexually reproducing organisms that results in gametes with half the chromosome number of the original cell.
  8. 16. any factor, abiotic or biotic, that influences living organisms.
  9. 17. A mutation occurring when the number of nucleotides inserted or deleted is not a multiple of 3, thus resulting in improper grouping into codons.
  10. 18. A haploid egg or sperm cell; unite during sexual reproduction to produce a diploid zygote.
Down
  1. 1. A cell containing two sets of chromosomes (2n), one set inherited from each parent.
  2. 2. A threadlike, gene-carrying structure found in the nucleus. Each one consists of one very long DNA molecule and associated proteins.
  3. 4. a linear sequence of nucleotides
  4. 6. A mutation involving the addition of one or more nucleotide pairs to a gene.
  5. 9. A type of reproduction in which two parents give rise to offspring that have unique combinations of genes inherited from the gametes of the two parents.
  6. 10. A change in a gene at a single nucleotide pair.
  7. 12. The act or process of being altered or changed
  8. 14. The reciprocal exchange of genetic material between nonsister chromatids during synapsis of meiosis
