In Summer Squash White Fruit Color W Is Dominant: The Allele ‘W’!
In the genetics of summer squash, the white fruit color is dominant. This is represented by the allele ‘W’.
When a squash plant carries this dominant ‘W’ allele, it will display a white color phenotype irrespective of the other allele it carries.
Dominance in genetics refers to the phenomenon where the effect of one allele, called the dominant allele, masks the effect of another allele, known as the recessive allele.
In the case of summer squash, ‘W’ denotes the dominant allele responsible for the white fruit color.
This means if a squash plant carries at least one ‘W’ allele, it will exhibit a white-colored fruit, regardless of the presence of any other recessive color alleles.
The white color of the fruit of summer squash is due to a gene which is dominant over its allele.
The presence of a dominant allele T triggers the albino gene and causes white color phenotype. As a result, white color of the fruit of summer squash is dominant.
3 Genotypes of White Fruit Color in Summer Squash
| Genotype | Fruit Color | Description |
|---|---|---|
| WW | White (dominant) | When a summer squash plant has two dominant alleles (WW), it will produce white fruits. This is because the allele for white fruit color (W) is dominant over the allele for yellow fruit color (w). |
| Ww | White (dominant) | Even when there’s one dominant allele (W) and one recessive allele (w) present (Ww), the dominant white allele will result in white fruits. |
| ww | Yellow (recessive) | Only when a summer squash plant has two recessive alleles (ww) will it produce yellow fruits. In this case, the recessive allele for yellow fruit color (w) expresses itself. |

It has become more popular in recent years due to its eye-catching appearance and can be found in some specialty markets.
For example, the popular ivory-skinned variety ‘White Wonder’ is often found in farmers’ markets, as well as other white fruit varieties.
Genetic Mechanism of White Color Phenotype
White color phenotype is a genetic phenomenon that occurs due to the absence of the pigment melanin.
It is the result of a genetic mutation in the melanocortin 1 receptor gene (MC1R) which is responsible for the production of melanin.
The MC1R gene is located on the chromosome 16 and is responsible for producing the enzyme called agouti signalling protein (ASP).
When the receptor is mutated, the production of ASP is decreased, resulting in a decrease in the amount of melanin that is produced. This causes the hair and skin to have a white color.
Other genes such as the tyrosinase gene (TYR) and the tyrosine hydroxylase gene (TH) also play a role in the production of melanin. Mutations in these genes can also lead to white color phenotype.
In some cases, white color phenotype can be inherited in a dominant, autosomal pattern.
This means that if one parent has the mutated gene, there is a 50 percent chance that the child will also have the mutation.
To sum up, white color phenotype is a genetic condition that results from the mutation of the MC1R gene. This mutation causes the decreased production of melanin, resulting in white hair and skin color.
Mutations in other genes such as the TYR and TH genes can also lead to this condition. In some cases, white color phenotype can be inherited in a dominant, autosomal pattern.
What is the Dominant Allele Responsible for White Fruit Color?
The dominant allele responsible for white fruit color is the Al-1 allele.
This allele is found in apples, pears, and quince, and it is responsible for the synthesis of a protein called anthocyaninase, which suppresses the production of anthocyanins and results in a lack of color in the fruit.
Some of the main characteristics of the Al-1 allele are:
An example of the Al-1 allele in action is the SnowSweet apple variety.
This variety is the result of a cross between a Red Delicious and a Golden Delicious apple.
The SnowSweet exhibits white fruit due to the Al-1 allele, despite being crossed with two red-fleshed apple varieties.
In conclusion, the Al-1 allele is the dominant gene responsible for white fruit color.
It can be inherited through either the maternal or paternal lineage, and its presence in the plant’s genome results in white fruit, regardless of other alleles.
How Does the Dominant Allele Trigger the Albino Gene?
The dominant allele is responsible for triggering the albino gene. This is a genetic trait that is responsible for causing an organism to lack pigment in their skin and hair.
The dominant allele is a gene that is expressed and visible in an organism’s phenotype, or physical features.
This gene has a higher chance of being inherited by the offspring and can mask any recessive alleles.
In certain cases, a recessive allele is necessary for the expression of the dominant allele.
The recessive allele can be associated with the albino gene, which means that two recessive alleles need to be present in order for the albino gene to be expressed.
However, the presence of a dominant allele can also mask the presence of a recessive allele.
This means that if one parent has a dominant allele, the albino gene may not be expressed even if another parent has the recessive allele.
For example, if one parent has a dominant allele for brown eyes, the albino gene will be masked and the offspring may have brown eyes despite the presence of the recessive allele for albinism.
Overall, the dominant allele is responsible for triggering the albino gene by either masking the presence of the recessive allele or by the presence of two recessive alleles.
What is the Genotype of Summer Squash With White Color?
The genotype of summer squash with white color is usually a recessive gene.
This means that the phenotypic expression of the white color is due to the presence of two recessive alleles in the genotype.
For example, if a plant has the genotype WW (where W represents the white color allele) then it will express the white color phenotype.
It is important to note that the presence of a single W allele is not enough to express the white color phenotype,
since the presence of a single dominant allele (such as the allele for yellow or green colors) will mask the presence of the recessive allele.
Bullet Point List:
How Does White Color Become Dominant?
White color is a dominant gene that is often used to breed animals with white coloration.
It is a simple genetic trait that is passed down through generations and is present in many different species of animals.
White color is usually dominant when the allele for white is present, and the allele for the alternate color is absent or recessive.
This means that if one parent has the white gene present, then the offspring will often be white as well.
In order for white color to become dominant, the allele for white must be present in the animal’s genetic makeup.
This means that if the animal’s parents both have the white gene, then the offspring will likely be white.
However, if one parent has the alternate color gene and the other has the white gene, then the offspring will typically be a mix of both colors.
An example of a species where white color is dominant is the domestic cat. Cats with white fur will often have a white fur gene that is passed down to the offspring.
Cats that do not have the white fur gene will usually have a mix of colors in their fur, like patches of black and brown.
Overall, white color is a dominant gene that is passed down from generation to generation. It is present in many different species of animals, like cats and dogs, and can be bred for if the proper genes are present.
