Fruit Colour In Cucurbita Pepo Is An Example Of
1. Identify the Phenotypes: - Cucurbita pepo exhibits three fruit colors: white, yellow, and green. - Among these, white is the most dominant color, while yellow and green are recessive.
Cucurbita pepo L. contains a fascinating array of fruit colors. A few genes affecting fruit exterior color have been identified, and their preferred symbols and names were recently summarized (2) as B (Bicolor) fruit), D, (Dark green stem), l (light fruit color), l-2 (light pigmentation on fruit-2), St (Striped fruit), W (White fruit), and Y.

Early Prolific Straightneck, a squash (Cucurbita pepo) cultivar having dark stems and lightly colored young fruits that intensify in color later in development, was crossed with an accession of. Solution: Fruit colour of summer squash (Cucurbita pepo) is governed by a gene which produces yellow colour in dominant state (Y) and green colour in recessive state (yy). Species Cucurbita pepo L., which includes marrow, squash, hard-barked pumpkin and a number of other crops, has a high polymorphism both in plant structure and in shape, size, color of the bark and fruit pulp.
The color of the bark of the fruits of this species can be white, cream, yellow, green, orange with or without a pattern. Appearance can greatly influence the marketing success of new. Fruit colour in Cucurbita pepo is an example of A.

Complementary genes B. Duplicate genes C. Dominant epistasis D.
Polymeric genes. Of the 13 genes described as affecting fruit color in Cucurbita pepo, one, D (Dark stem), also markedly affects stem color. The D allele confers dark stems and dark intermediate-age fruits, is dominant to the d allele for light stems and fruits, and epistatic to two recessive genes conferring light fruit coloration, l-1 and l-2.

However, a gene for light fruit coloration, W (Weak fruit color. Introduction: Thirteen loci affecting fruit color have been identified in Cucurbita pepo L. (2).
One of these loci, D, affects both, the color of the stem and the color of the intermediate-age and mature fruit (3). Plants of the recessive d/d genotype have light green stems. The dominant allele, D, causes the plant stem to become dark green at a young age, making it a useful phenotypic marker.
The color of the mature fruit flesh is most often light yellow-orange, but can range from greenish white to intense orange; it can be relatively thick or thin, and coarsely fibrous and tough to finely fibrous and tender (Paris, 2008). Whitwood (1975) studied the inheritance of tendril development and mature fruit color in Cucurbita pepo. The association between the fruit pigmentation, chilling sensitivity and tocopherol levels in Cucurbita pepo may be related to the effects of the fruit color genes on plastid development.
