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
If orange flower color in a plant is controlled by and allele f and red flower color is controlled by and allele f which flower color is dominant?
Orange
If a pea plant has a recessive allele for green peas it will produce?
green peas if it does not also have a dominant allele for yellow peas.
What combination of alleles could produce a trait controlled by a dominant allele?

What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.

Is fragile x syndrome controlled by a dominant allele?
yes
If orange flower color in a plant is controlled by and allele f and red flower color is controlled by and allele f which flower color is dominant?
Orange
How does a dominant trait affect the phenotype of an organism?
If the the trait is controlled by only one allele and the allele is completely dominant then once inherited the offspring with exhibit that phenotype
What allele combinations could a plant with green and wrinkled seeds produce in a gamete?
Ressive genes. Smooth seeds are dominant in the pea plants Mendel used in his experiments.
If a pea plant has a recessive allele for green peas it will produce?
green peas if it does not also have a dominant allele for yellow peas.
If a pea plant has a allele for green peas it will produce?
green peas if it does not also have a dominant allele for yellow peas.
What is recessivr allele?
For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent. An individual with one dominant and one recessive allele for a gene will have the dominant phenotype.
What combination of alleles could produce a trait controlled by a dominant allele?
genotype
