2. Tabulate any ten vocabularies used in Mendelian genetics with its definition and example.
answer :
Vocabulary | Definition | Example |
---|---|---|
Allele | One of two or more versions of a gene | A gene that controls flower color can have the alleles R (red) and W (white). |
Dominant | An allele that is expressed when present in a heterozygous individual | The R allele is dominant, so an individual with the genotype Rr will have red flowers. |
Recessive | An allele that is only expressed when present in a homozygous individual | The W allele is recessive, so an individual with the genotype WW will have white flowers. |
Genotype | The genetic makeup of an individual | An individual with the genotype Rr has one copy of the R allele and one copy of the W allele. |
Phenotype | The physical or observable traits of an individual | The phenotype of an individual with the genotype Rr is red flowers. |
Homozygous | Possessing two copies of the same allele for a gene | An individual with the genotype RR is homozygous for the R allele. |
Heterozygous | Possessing two different alleles for a gene | An individual with the genotype Rr is heterozygous for the R allele. |
Monohybrid cross | A cross between two individuals that differ by a single gene | A cross between an individual with the genotype Rr and an individual with the genotype WW would be a monohybrid cross. |
Dihybrid cross | A cross between two individuals that differ by two genes | A cross between an individual with the genotype RrYy and an individual with the genotype WWyy would be a dihybrid cross. |
