Fruit Colour In Summer 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.

The summer squash fruit colour can be white, yellow or green. White fruits producing epistatic alleles are 'W'. Y is for yellow fruits which is dominant to y which is for green fruits. White masks the effect of yellow or green. Hybrid ratio obtained is 12 white: 3 yellow: 1 green.

White fruit color in summer squash is dependent on dominant allele W and colored fruit on recessive allele w. In the presence of ww and a dominant gene G, the color of the fruit is yellow.

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.

In certain species of summer squash, fruit color is determined by two interacting genes. A dominant allele, W, determines white color, and a recessive allele, w, allows the fruit to be colored. In a homozygous ww individual, a second gene determines fruit color: G (green) is dominant to g (yellow). A white squash and a yellow squash were crossed, and the F1 generation yielded approximately 50%.

White fruit color in summer squash is dependent on dominant allele W and colored fruit on recessive allele w. In the presence of ww and a dominant gene G, the color of the fruit is yellow.

An example of dominant epistasis is found for fruit colour in summer squash. There are three types of fruit colours in this cucumber, viz., white, yellow and green.

Fruit color in summer squash is an example of epistasis, where genotypes W produce white fruit, wwyy produce green fruit, and ww, YY, or Yy produce yellow fruit.

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.

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.

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.
