|---|---|---|---|---|---|
| Mendel | father of genetics
🗑
|
||||
| cross-fertilize | a plant from another place fertilizes it
🗑
|
||||
| self-fertilize | a plant fertilizes itself
🗑
|
||||
| Hybrid | fertilization in which the sex cells are produced by two different individuals or sometimes by individuals of different kinds
🗑
|
||||
| P generation | the parents (the 1st generation)
🗑
|
||||
| F1 Generation | offspring or kids of the P generation (2nd generation)
🗑
|
||||
| F2 Generation | kids of the kids of P Generation ( the 3rd generation)
🗑
|
||||
| Monohybrid cross | crossbreeding experiment that follows the inheritance of a single characteristic across one or more generations
🗑
|
||||
| Dihybrid cross | a cross between the F1 offspring of two individuals that differ in two traits of particular interest
🗑
|
||||
| Dominant Allele | a gene that is expressed in an organism's phenotype masks a recessive gene (always expressed)
🗑
|
||||
| Recessive allele | it's hidden (a gene whose phenotype expression is masked by a dominant gene
🗑
|
||||
| Homozygous | two of the same allele that code for the same trait
🗑
|
||||
| Heterozygous | one of each allele that code for the same trait
🗑
|
||||
| Carriers | they have the trait but don't show it
🗑
|
||||
| Recessive Disorders | can be hidden. ex: Cystic fibrosis, albinism, PKU (phenylketonuria), Sickle cell disease. tay-sachs disease
🗑
|
||||
| Dominant Disorders | Dwarfism (achondroplasia), huntingston's disease, alheimers, hypercholesterlemia
🗑
|
||||
| Genotype vs.Phenotype | 1) order of letter 2)how they are expressed
🗑
|
||||
| Complete | 1) Inheritance characterized by an allele that is fully expressed in the phenotype of a heterozygote and that masks the phenotypic expression of the recessive allele
🗑
|
||||
| Incomplete Dominance | neither can mask the other( the appearance in a heterozygote of a trait that is intermediate between either of the trait's homozygous phenotypes
🗑
|
||||
| Codominance | both get expressed( a condition in which both alleles of a gene pair in a heterozygote are fully expressed, with neither one being dominant or recessive to the other.
🗑
|
||||
| Pleiotropy | one bad gene creates a multitude of effects
🗑
|
||||
| polygenic inheritance | many genes affect one trait
🗑
|
||||
| Monoecious | plant species that are both male and female
🗑
|
||||
| Hermaphroditic | animal species that are both male and female
🗑
|
||||
| sex-linked disorders | red-green color blindness, hemophilia, duchenne muscular dystrophy
🗑
|
||||
| Principle of segregation | chromosome from mom and chromosome from dad separate during meiosis
🗑
|
||||
| Test cross | a cross between an individual exhibiting the dominant phenotype of a trait and an individual that is homozygous recessive for that trait in order to determine the genotype of the dominant individual
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
