Biology Genetic Terms
| Question | Answer |
|---|---|
| heredity | passing on of characteristics from parents to offspring |
| trait | characteristic that is inherited, can be dominant or recessive |
| genetics | branch of biology that studies heredity |
| gamete | male and female sex cells, sperm and egg |
| fertilization | fusion of male and female gametes |
| zygote | diploid cell formed when a sperm fertilizes an egg |
| pollination | male reproductive organs to female reproductive organs of plants, usually the same species. Asexual Reproduction. |
| hybrid | offspring of parents having different forms of a trait |
| allele | different forms of a gene for each variation of a trait of an organism |
| dominant | trait that masks the recessive for of the trait |
| recessive | trait that can be masked by the dominant form of the trait |
| law of segregation | each plant has 2 different alleles, can produce 2 different types of gametes. Male and female gametes randomly pair to produce 4 allele combinations |
| phenotype | outward appearance of an organism, regardless of genes |
| genotype | combination of genes in an organism |
| homozygous | two identical alleles for a trait |
| heterozygous | two different alleles for a trait |
| law of independent assortment | genes for different traits are inherited independently of each other |
