The traits were recessive.
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.
In a simple cross, the ratio of dominant to recessive is 3:1
the answer below is wrong the right aswer is: one fourth
none.
3:1
none
yes
The expected phenotype for a Mendal F1 monohybrid cross is 3:1. Looking at heterozygous parents (F1) who share the same dominant trait, e.g. Straight tail.Crossing two heterozygous parents from the F1 generation results in an F2 generation that produces a 75% chance for the appearance of the dominant phenotype, of which two-thirds are heterozygous, and a 25% chance for the appearance of the recessive phenotype, giving the ratio 3;1.Inheritance pattern of dominant and recessive phenotypes when each parent is homozygous for either the dominant or recessive trait. All members of the F1generation are heterozygous and share the same dominant phenotype, while the F2generation exhibits a 3:1 ratio of dominant to recessive phenotypes.
the dominant trait
C) traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1
No. A recessive trait is masked by a dominant trait.
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.
(Apex Learning) 3:1.

3:1 homozygous dominant, heterozygous dominant, heterozygous dominant and homozygous recessive.
the dominant trait
Phenotypes are the entirety of the observable traits. Genotypes are the instructions in the genetic code. Dominant alleles override the recessive alleles, making only the dominant alleles expressed.
C) traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1
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).
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.
The outward expression of genetic traits are called phenotypes. Phenotypes expression include recessive and dominant genes such as eye and hair color.
No. A recessive trait is masked by a dominant trait.
The dominant trait is shown in that organism with the possibility of carrying either the dominant or recessive gene to the next generation
