Fruit Colour In Squash Is An Example Of

Example of dominant epistasis is the colour of the summer squash fruit. So, option B is the correct answer. Note: The phenotype is not necessarily dependent on the genotype of an organism. The phenotype of an individual depends on the expression of the genotype. Expressivity is the intensity with which a particular genotype is expressed. Analyzing Fruit Color in Squash: In summer squash, the fruit color can be white, yellow, or green. The white fruit color is produced by a dominant epistatic allele (W). 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. A dominant epistasis is a condition when a dominant gene masks the effect of the other non-allelic gene. In summer squash, the fruit color may be white, yellow, or green. White fruits are produced by a domain epistatic allele 'W'. At another locus, Y for yellow fruits is dominant to its allele y for green fruits. Dominant white hides the effect of yellow or green. A consequence of this. The expression of fruit colour in squash shows the phenomenon ofdominant epistasis in whichthe dominant allele of one gene masks the expression of all the alleles of. Text solution Verified 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). Squash fruit appear white due to the epistatic effect of 'W' allele (white colour) over 'G' allele (green colour). 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. 4. Analyzing Fruit Color in Squash: In summer squash, the fruit color can be white, yellow, or green. The white fruit color is produced by a dominant epistatic allele (W). This means that if the W allele is present, it will mask the effects of other alleles that determine the fruit color. 5.
