Step-by-Step Solution: 1. Understanding the Question: The question asks about the genetic basis of fruit color in squash. We need to identify the type of genetic interaction that leads to the expression of different fruit colors.
2. Identifying the Phenotypes: In squash, there are three observed fruit colors: white, yellow, and green. Hint: Fruit squash can be found in white with green or yellow color.
What color the fruit will majorly depend on genetics. The color selection follows a dihybrid cross which is crossed over between a homozygous pair of alleles (white and yellow) and homozygous pair of alleles (white and green). Complete answer: > Epistatic genes are genes that control the expression of alleles.
They can be. In summer squash or Cucurhita pepo, there are three types of fruit colour' yellow, green and white. White colour is dominant over other colours while yellow is dominant over green.
Yellow colour is formed only when the dominant epistatic gene is represented by its recessive allele (w). Inheritance of fruit color in summer squash provides an example of the phenomenon of epistasis. Yellow fruit is produced by a cross involving the homozygous recessive expression of the W gene (ww) and either the homozygous dominant (YY) or heterozygous (Y y) form of the Y gene.
The wwyy outcome is green fruit. If squash fruit colour was an example of dominant epistasis, it would mean that the presence of a dominant allele at a specific locus determines the fruit colour. Answers (1) The fruit colour of squash is due to the dominant epistasis.
Epistasis is the process where one dominant gene masks the expression of the other gene. Thus, the correct answer is option b. Fruit colour in squash is an example of dominant epistasis in which the dominant gene (epistatic gene) masks the effect of other gene (recessive hypostatic gene).
