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