Is the difference between a dominant and recessive allele?
dominant-appears in first generation recessive-seems to dissapear
In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
3:1 homozygous dominant, heterozygous dominant, heterozygous dominant and homozygous recessive.
A trait that appears or is expressed in the f1 generation is what?
the dominant trait
Mendel accounted for the observation that traits which had disappeared in the F1 generation reappeared in the F2 generation by proposing that?
C) traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1
What was the ratio of dominant of recessive phenotypes in the F2 generation of Mendel's experiments?
The traits were recessive.
Is it true that mendel assumed that a dominant allele had masked the corresponding recessive allele in the f1 generation?
No. A recessive trait is masked by a dominant trait.
If an offspring receives a pair of trait-controllers containing both a dominant and a recessive trait what happens to the recessive trait?
The dominant trait is shown in that organism with the possibility of carrying either the dominant or recessive gene to the next generation
According to mendel what genes disappear in f1 pea plants?
No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both a dominant and recessive alleles. The recessive phenotype disappears in the F1 generation because all members of that generation carry a dominant allele. In the F2 generation, the recessive phenotype will reappear.
In the mendels experiment why did traits show up in the f2 generation that were not present in the f1 generation?
All of the F1 generation are heterozygous, therefore 100% exhibit the dominant phenotype. The F2 generation has a ratio of 1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. This results in a phenotypic ratio of 3 dominant: 1 recessive.

What term can describe the genotypes of the p generation?
homozygous dominant and homozygous recessive
