If 675 plants resulting from the cross display a trait controlled by a dominant allele how many plants will show the trait controlled by the recessive allele?
In a gene loci there can be four combinations of 2 alleles. Suppose these possible allele combinations are called D for dominant and R for Recessive. The possible combinations for two of them are DD, DR, RD and RR. Wherever the D occurs the dominant trait will be displayed. There is only 1 where the recessive trait is displayed and this is the last or RR case. There must be 3 times the number of cases of the dominant trait as the recessive so the recessive trait is displayed in 675 / 3 cases or 225
In a typical Mendel experiment on pea-seed color if the dominant yellow seed-bearing plant was crossed with the recessive green seed-bearing plant the F2 generation will show what ratio of each kind?
The F2 generation will exhibit a phenotypic ratio of 3:1, with three quarters of the plants displaying the dominant yellow seed phenotype and one quarter displaying the recessive green seed phenotype. This follows the typical 3:1 ratio observed in a monohybrid cross involving a dominant and recessive trait.
The recessive traits reappeared in the F2 generation in approximately 25 percent of the plants?
50% because it divided half to
According to Mendel what kind of genes disappear in F1 pea plants?
No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both 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.
When Mendel crossed two plants that were hybrid for stem height (Tt) three fourths ( and frac34) of the F1 plants had short stems.?
This indicates that the short stem trait is dominant. Mendel's expected ratio for a monohybrid cross with dominance is 3:1, with three quarters (75%) showing the dominant trait (short stems) and one quarter (25%) showing the recessive trait (tall stems).
When a first generation plant self pollinates what is the ratio of dominate to recessive traits in the second generation plants?
When a first generation plant self pollinates, the ratio of dominant to recessive traits in the second generation plants is typically 3:1. This is based on Mendel's principle of segregation, which predicts that in a monohybrid cross, three plants will exhibit the dominant trait and one will exhibit the recessive trait.

What did Gregor Mendel study?
He studied dominant and recessive genes. He studied pea plants and the traits that they obtained from previous generations.

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.
Trait of an organism that can be masked by the dominant by the dominant form of a trait?
A recessive trait is a characteristic of an organism that can be masked by the dominant form of a trait. It is only expressed when an individual inherits two copies of the recessive allele. Examples include blue eye color being masked by brown eye color.
In which generation were recessive in all the plants in medel's experiment?
In Mendel's experiments, the recessive traits were observed in the F2 generation. Initially, the traits were not visible in the F1 generation, where only the dominant traits were expressed. However, when the F1 plants were allowed to self-pollinate, the recessive traits reappeared in the F2 generation, typically in a ratio of about 3:1, dominant to recessive.
In mendels model of segregation what was the ratio of tall plants to short plants in the F2 generation?
3 dominant to 1 recessive
What did Mendel discovered about the pea plants reproduction process?
Some are dominant and some are recessive.
