In mendels experiment a trait that always disappeared in the f1 generation but reappeared in the f2 generation was called the?
recessive trait
A trait that appears or is expressed in the f1 generation is what?
the dominant trait
In Mendel's experiment why did traits show up in the f1 generation that were not present in the f1 generation?
the traits were recessive
What did mendel find in the f1 generation?
he crossed two pure lines
When studying a pedigree how do scientists determine if a trait is dominate or recessive?
dominant only appears in the F1 generation as 4 recessive stays hidden or masked in the F1 generation
In mendels experiment a trait that always disappeared in the f1 generation but reappeared in the f2 generation was called the?
recessive trait
What is the phenotype in the F1 generation that disappears in a one trait test cross?
The recessive trait phenotype disappears in a one-trait test cross in the F1 generation. This phenotype can reappear in the F2 generation.
If the F2 generation expressed a trait in a 3.1 ratio the F1 generation MUST be heterozyous for that trait?
True
A trait that appears or is expressed in the f1 generation is what?
the dominant trait
In Mendel's experiment why did traits show up in the f1 generation that were not present in the f1 generation?
the traits were recessive
What trait or traits did the plants in the F1 generation exhibit?
tall and tall
What did mendel find in the f1 generation?
he crossed two pure lines
When do you first learn which trait is dominant?
when observing the F1 generation of a monohybrid cross
What phenotypes are present in F1 generation?
The phenotypes present in the F1 generation depend on the phenotypes of the parental generation (and the environment). The F1 generation will display the dominant trait(s). For example, if T is tall and t is short, in the cross TT X tt the F1 generation will have the phenotype corresponding to the T allele (tall).
When studying a pedigree how do scientists determine if a trait is dominate or recessive?
dominant only appears in the F1 generation as 4 recessive stays hidden or masked in the F1 generation
A trait in the f1 generation that is different from the parental phenotype is known as?
A trait in the f1 generation that is different than that of the parental phenotype is known as a hybrid. This occurs as a result of two distinctly different parents producing a phenotype that is uniform and new.
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
