Question | Answer |
What did Mendel conclude about traits? | They are inherited through the passing of factors from parents to offspring. |
The farther apart two genes are located on a chromosome: | The less likely they are to be inherited together. |
In the P generation, a tall plant was crossed with a short plant. No F1 plants were short. Short plants reappeared in the F2 generation because: | The allele for shortness and the allele for tallness segregated when the F1 plants produced gametes. |
Probability can be used to: | Predict the traits of the offspring produced by genetic crosses. |
Principle of independent assortment | During gamete formation, genes for different traits separated without influencing each other's inheritance. |
Intermediate inheritance | Cross of a black chicken and a white chicken produces all blue offspring |
Polygenic inheritance | variation in human skin color |
Mendel crossed a true-breeding tall plant with a true-breeding short plant. The F1 plants inherited: | an allele for tallness from the tall parent and an allele for shortness from the short parent |
In the P generation, a true-breeding tall plant (dominant) was crossed with a true-breeding short plant. If alleles did not segregate during gamete formation: | All the F2 plants would be tall. |
Hybrids | Offspring that result from crosses between true-breeding parents with different traits |
Mendel crossed true-breeding purple-flowered plants with true-breeding white-flowered plants. All the offspring were purple because: | the allele for purple-flowered plants is dominant. |
Homozygous | Organisms that have two identical alleles for a trait. |
A Punnett square shows: | The possible results of a genetic cross, but not the actual results. |
The sex-linked allele for colorblindness is located on: | the X chromosome |
If a woman who is a carrier of a sex-linked trait married a man with the trait, the chance that the child would have the trait would be: | 50 % |
A carrier of a recessive disorder | has one copy of the allele and does not exhibit symptoms. |
