MENDELIAN GENETICS
| Question | Answer |
|---|---|
| Who is known as the father of genetics | Gregor Mendel |
| What type of plants did Mendel study | Pea plants |
| What is the Law of Segregation | Each allele separates into different gametes during meiosis |
| What is the Law of Independent Assortment | Genes for different traits are inherited independently of one another |
| What is a dominant allele | An allele that masks the expression of another allele |
| What is a recessive allele | An allele that is hidden when a dominant allele is present |
| What is genotype | The genetic makeup of an organism (allele combinations) |
| What is phenotype | The physical appearance of a trait |
| What is a homozygous genotype | Having two identical alleles for a trait (AA or aa) |
| What is a heterozygous genotype | Having two different alleles for a trait (Aa) |
| What tool is used to predict the outcomes of a genetic cross | Punnett square |
| Which process during meiosis allows for independent assortment | Random orientation of homologous chromosomes in metaphase I |
| How many alleles are inherited for each trait | Two, one from each parent |
| What is the purpose of a test cross | To determine the genotype of an organism showing a dominant trait |
| What is a hybrid | Offspring from parents with different alleles for a trait |
| What is a purebred | Offspring of parents with identical alleles for a trait |
