Bio genetics part 2

Biology 2017 Genetics test review part 2

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.
