Across
  1. 3. occurs early in meiosis (metaphase I); is a process that breaks and recombines pieces of DNA to produce new combinations of genes
  2. 4. a cell or organism that has paired chromosomes, one from each parent
  3. 5. an organism’s set of heritable genes that can be passed down from parents to offspring
  4. 6. the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
  5. 11. each gamete inherits only one copy of each chromosome; each chromosome has only one copy of each gene, so each gamete only gets one allele
  6. 13. a genetic condition in which an individual inherits different alleles for a particular gene from each parent
  7. 18. the quality of a cell or organism having a single set of chromosome
  8. 19. any cell other then a reproductive cell
  9. 22. A reproductive cell containing one set of chromosomes and half the genetic information needed to make a organism
  10. 23. the action or process of fertilizing an egg, involving the fusion of male and female gametes to form a zygote
  11. 27. a graphical representation of the possible genotypes of offspring arising from a particular cross or breeding event
  12. 29. genes which are closer together on the same chromosome, causing the alleles to be inherited together as a group more frequently than not
  13. 30. The alleles of different genes get sorted into gametes independently of one another
  14. 31. The likely hood of a event happing or predicting a outcome in genetics
Down
  1. 1. new organism made by living things
  2. 2. an organism's physical appearance shows a blending of both alleles; occurs when a dominant allele does not completely mask the effects of a recessive allele
  3. 7. person with blood type AB who can receive all types of blood; presence of both antigens allows for “foreign” blood to not be recognized as a threat
  4. 8. a diagram showing the occurrence and appearance of phenotypes of a particular gene throughout multiple generations
  5. 9. a version of a gene that will produce a certain appearance/trait, even in the presence of other alleles
  6. 10. an organism's physical appearance is an expression of BOTH alleles simultaneously; occurs when neither allele is fully dominant to the other
  7. 12. female gamete
  8. 14. Male gamete
  9. 15. a special type of cell division used by sexually-reproducing organisms to produce gametes involves 2 rounds of division that result in four haploid cells that contain one copy of each maternal and paternal chromosome
  10. 16. small haploid cell formed as an egg but doesn’t have the ability to be fertilized
  11. 17. when two separate eggs are fertilized by two separate sperm cells
  12. 18. a genetic condition in which an individual inherits the same alleles for a particular gene from both parents
  13. 20. single fertilized egg splits in two
  14. 21. a given trait with 3 or more alleles
  15. 24. characteristics or attributes of an organism expressed by genes
  16. 25. one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
  17. 26. donors with blood type O; this blood type is lacking both the A and B antigens
  18. 28. a version of a gene which will not create the corresponding appearance/trait if a dominant allele is present
