Across
  1. 2. chromosome, a chromosome carrying a new combination of alleles created by crossing over
  2. 4. inheritance where both alleles in a heterozygote are fully and simultaneously expressed
  3. 5. cell, a cell produced from the division of a parent cell after mitosis or meiosis
  4. 6. an organized visual profile of an individual's chromosomes arranged by size, shape, and number
  5. 7. a cell or organism with a single set of chromosomes (one copy of each chromosome)
  6. 9. over, exchange of genetic material between homologous chromosomes during meiosis that produces new allele combinations
  7. 11. organisms that produce offspring identical to the parent for a trait when self‑fertilized or crossed with the same genotype
Down
  1. 1. inheritance where heterozygotes display an intermediate phenotype between the two homozygotes
  2. 3. a diagram used to predict genotype and phenotype ratios of offspring from a genetic cross
  3. 5. a cell or organism with two complete sets of chromosomes (two copies of each chromosome)
  4. 8. an allele that masks the expression of another allele when present in a single copy
  5. 10. an allele whose phenotype is expressed only when two copies are present (masked by a dominant allele)
  6. 12. variation, differences in DNA sequences or observable traits among individuals in a population
