Basic Genetics
| Question | Answer |
|---|---|
| asexual reproduction | reproduction requiring only one parent where offspring is a genetic clone of the parent |
| sexual reproduction | reproduction requiring two parents and allows for genetic diversity of traits |
| sex cells | cells used in sexual reproduction, male and female reproductive cells |
| body cells | all cells that are not used in reproduction and have double the chromosomes |
| gametes | proper term for egg and sperm cells |
| zygote | the first fertilized body cell |
| Dominant | an allele whose trait that always shows up if it is present |
| Recessive | an allele whose trait is hidden in the presence of a dominant allele |
| Phenotype | an organism's physical appearance or visible trais |
| Genotype | the genetic makeup of an organism |
| homozygous | having 2 identical alleles for the same trait |
| heterozygous | having 2 different alleles for the same trait |
| purebred | Offspring that has the same form of traits, another name for homozygous |
| hybrid | Offspring that has a different form of traits, another name for heterozygous |
| Punnett Square | tool used to predict the probability of a trait showing up in the offspring |
| allele | all of the different forms of a gene |
| haploid | sex cells containing half of the number of chromosomes of the body cells |
| diploid | body cells containing double the number of chromosomes of the sex cells |
