| Question | Answer |
|---|---|
| The different form of gene of a trait are called | Alleles |
| You inherit one allele from your _____ and one from your ______ | Mom, Dad |
| The letter representing the genetic makeup of an individual are know as its | Genotype |
| The physical characteristics(appearance) of an individual (the expression of the genes) are know as the | Phenotype |
| If one allele masks or covers up by another allele,its the _______ allele | Dominate |
| The allele that is masked or covered up by another is a ____ allele | Recessive |
| Capital letter represents the ________ allele.Lowercase letters represents the ______ cells | Dominate , Recessive |
| If you have two dominate alleles,you are | Homozygous dominate |
| If you have recessive alleles you are | Homozygous recessive |
| if you have a dominate allele and a recessive allele,you are | Heterozygous |
| Another name for homologous is | pure |
| Another name for hetrozygous is | hybrid |
| Does AA represent:the genotype or the phenotype | Geonotype |
| Is AA homozygous or heterogeneous | Homozygous |
| A cross between two individuals with one trait is called a ____ cross | Monohybrid |
| A cross between two individuals two the 2 traits is called a | Dihybrid |
| The grid that is used to predict the probability of the the outcome of crossing two individuals with certain genotypes is called a | Punnet square |
| The diagram used to trace the history of a dominate or recessive trait in a family is called a | Pedigree |
| With complete dominance, one trait ______ another trait in the heterogeneous condition. | masks |
| with incomplete dominance,the trait _____ in the heterozygous condition | blend |
| With co-dominance,the traits are ____ expressed in the hetrozygous condition | both |
| if red flowered plants are governed by complete dominance over a white flowered plant,what color would Rr plants be | Red |
| if the red flowered planets are governed by co dominance dominance over white flowers plants,what color would Rr plants be | red and white |
| if you cross a pure red flower plant with a pure white flower plant governed by complete dominance,what is the probability of have a red flowered planet______ white flowered plant______ | 100%, 0% |
| If you cross two hetrozygous red flowered plant governed by complete dominance ,what is the probability of having a red flowered plant______ white lowered plant ______ | 75%, 25% |
| XX is ______ XY is a _____ | female, male |
| if a male and a female have a child,what is the probability of the child being male_____ female____ | 50%, 50% |
| which parent determiners the sex of the child | male/dad |
| when several genes contribute to the expression of the trait,the trait is | Polygenic |
| when one gene's expression is governed by another gene,the trait is | epistasis |
| Person 1 on the P row represents the _____ person 2 on the P row represents the ______ | Male, female |
| How maney children did P1 and P2 have | 3 |
| Does person 2 on the F1 row have a recessive allele | Yes because it child 3 has a disorder |
| is person 5 on the F1 row a child P1 and P2 | No |
| How meany boys did person 4 and 5 of the F1 row have | 1 |
| the diagram is called a | Pedigree |
| Is the disorder represented by shading or non shading | Shading |
| if a red flower plants are governed by incomplete dominance over a white flower plants what color would Rr plant be | pink |
