Genetics
Gregor Mendel
| Question | Answer |
|---|---|
| Genetics | The scientific study of heredity |
| Allele | Alternate forms of a gene / factor |
| Genotype | Combination of alleles an organism has (Tt) |
| Phenotype | How an organism appears |
| Dominant | An allele which is expressed (masks the other) |
| Recessive | An allele which is present but remains unexpressed (masked) |
| Homozygous | Both alleles for a trait are the same |
| Heterozygous | The organism's alleles for a trait are different |
| What plant did Gregor Mendel experiment with? | Pea plants |
| Law of Segregation | When gametes are formed each gamete will receive one allele or the other |
| Law of independent assortment | Two or more alleles will separate independently of each other when gametes are formed |
| Punnett square | Square diagram that is used to predict genetic probabilites |
| Monohybrid cross | Cross with only 1 trait |
| Genotypic ratio | 1:2:1 |
| Phenotypic ratio | 9:3:3:1 |
| Dihybrid cross | A cross between two different genes that differ in two traits |
| Monohybrid cross | A cross between parents that differ in the alleles they possess for one particular gene |
| Are all chromosomes homologous? | No, all except sex chromosomes are homologous |
| What is ABO blood typing? | The classification of human blood, there is type A, type B, type O, and type AB |
| Multiple Alleles | When there are more than 1 alleles (ex: human blood) |
| Incomplete dominance | A gene is not completely dominant over the other, which results in mixing |
| Gene interaction | When any of the steps are altered, the end product of the path way may be disrupted |
| Codominance | Both alleles are expressed equally |
| Who was Gregor Mendel? | A monk who discovered the basic principles of heredity |
