Question | Answer |
What is an alternative form of a gene | allele
|
All chromosomes in an organism EXCEPT sex chromosomes | autosomes
| One molecule of DNA-carries genes | chromosome
| Represents a mating pair | cross
| Cells with complete set of chromosomes (2N=) | diploid
| Trait that is always expressed if present | dominant
| Sex cells (egg/sperm) | gamete
| Short segment of DNA that codes for a particular trait | gene
| Shows the genetic make-up of an organism | genotype
| Cells that contain half the chromosomes (1N=) | haploid
| Transfer of genetic information/characteristics from parent to offspring | heredity
| 2 different alleles for a trait; 1 dominant, 1 recessive | heterozygous
| 2 identical alleles for a trait; 2 dominant AA, 2 recessive aa | homozygous
| Physical appearance of the organism based on genotype | phenotype
| Trait only expressed if no dominant allele is present | recessive
| Fertilized egg from fusion of egg and sperm | zygote |
