Genetics
| Question | Answer |
|---|---|
| allele | different forms of the same gene |
| dihybrid cross | two characteristics being studied |
| dominant allele | one that gets expressed. prevents recessive allele in heterozygous |
| genotype | genetic makeup of a organism |
| heredity | passing on characteristics through genes from one generation to the next |
| heterozygous | two alleles are different |
| homozygous | two alleles are the same |
| incomplete dominance | neither dominant nor recessive allele is produced. expressed in heterozygous but intermediate phenotype is produced |
| law of independent assortment | each member of a pair of alleles may combine randomly with either of another pair of alleles |
| law of segregation | inherited characteristics are controlled by alleles, these factors separate at gamete formation, one member of each pair left in each gamete |
| phenotype | physical appearence |
| recessive | allele prevented from being expressed by a dominant allele |
| autosomes | chromosomes that work automatically |
| sex chromosomes | XX female, XY male |
| linkage | genes/alleles on the same chromosome |
| locus | a genes position on a chromosome |
| gene | a piece of DNA coded for protein |
| monohybrid | one characteristic study |
| dihybrid | two characteristic study |
| species | a group of organisms interbreed and produce offspring |
| examples of sex-linked characteristics | colour blindness and albinism |
