What shapes do the epidermal cells of tomatoes exhibit and what is the color of the dominant pigments here?
Epidermal cells of tomatoes typically exhibit a polygonal shape, often resembling hexagons or irregular polygons due to their close packing. The dominant pigments in these cells are primarily carotenoids, which give tomatoes their characteristic red color, particularly lycopene. Additionally, chlorophyll may be present in younger, green tomatoes, contributing to their green coloration before ripening.

What gene will exhibit its traits even in a prensesce of a recessive gene?
A dominant gene will exhibit its traits even in the presence of a recessive gene. This is because the dominant gene masks the expression of the recessive gene when present in the same individual.
What is a dominant alle?
A dominant allele is a genetic variant that masks the presence of a recessive allele when an individual carries both. In an individual's genetic makeup, only one copy of a dominant allele is required to exhibit the corresponding trait or characteristic.
Is hitchhikers thumb dominant or recessive allele?
Hitchhiker's thumb is caused by a dominant allele. Individuals with at least one copy of the dominant allele will exhibit the thumb's characteristic flexibility, while those with two recessive alleles will have a straight thumb. This trait is a classic example of simple Mendelian inheritance.

What is the probaility that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype?
100 percent.
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 is the percentage of offspring that will exhibit the dominant trait from A crossing of A homozygous dominant and homozygous recessive individual?
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.
What is the phenotypic ratio of the following dihybrid cross AaBb x AaBb?
The phenotypic ratio of the cross AaBb x AaBb is 9:3:3:1, which represents the different possible combinations of genotypes for the offspring based on the principles of Mendelian genetics. This ratio indicates that 9 out of 16 offspring will exhibit the dominant phenotype for both traits, while 3 out of 16 will exhibit one dominant and one recessive phenotype, 3 out of 16 will exhibit the other dominant and recessive phenotype, and 1 out of 16 will exhibit both recessive phenotypes.
What is the probability that the offspring of a homozygous dominant individual and a homozygous recessive individual exhibit the dominant phenotype?
Given those conditions, the offspring have a 50% chance of demonstrating the dominant phenotype and a 50% chance of demonstrating the recessive phenotype.
Is mid-digital hair a recessive or dominant gene?
Mid-digital hair is considered a dominant genetic trait. This means that if an individual inherits the allele for mid-digital hair from either parent, they will exhibit the trait.
Will an organism with a recessive allele for a particular form of a trait will always exhibit that form?
No, an organism with a recessive allele for a particular trait will only exhibit that form if it has two copies of the recessive allele (homozygous recessive). If it has one dominant allele, it will exhibit the dominant form of the trait.
What is a dominant alle?
A dominant allele is a genetic variant that masks the presence of a recessive allele when an individual carries both. In an individual's genetic makeup, only one copy of a dominant allele is required to exhibit the corresponding trait or characteristic.
How would you know if you had a dominant gene?
You would know if you had a dominant gene if you exhibit the trait associated with that gene. Dominant genes override recessive genes when inherited, so if you have a dominant gene, you will express the associated trait in your physical appearance or characteristics. A dominant gene will be expressed in the presence of a recessive gene.
