You\'re an orchid breeder and have noticed that you have a few plants that display a totally novel golden coloring pattern. This purple and gold pattern has basically made you a LEGEND in your horticulture club, and now your best friend wants to use your sweet orchids in their wedding. Obviously, getting a purebreeder line would be ideal for cranking up production... because you pal is going to need A LOT of flowers. But this is proving to be a challenge; every time two golden orchids are crossed, you end up with a fair number of gold flowers, but still a significant number of orchids featuring the standard white coloration. In your most recent purple and gold orchid self cross, you ended up with 113 gold and 57 standard orchids. All other such matings gave similar phenotypic offspring ratios. What\'s going on here? And explain why you think that. (

Solution

the things here is the cross of gold and white produces phenotype Pp which means P=50% and p=50%

.As a result the gold ones are 113 and standard ones are 50% ofgold=53
