If g=yellow and g=green peas, and at a separate gene p=purple and p=white flowers, what proportion of your offspring will be yellow and white if you cross a ggpp with a ggpp?

1/4

Explanation:

Given the genotype of parent plants: Ggpp and ggPp. The parent plant with Ggpp genotype will form two types of gametes in 1:1 ratio= Gp and gp.

The parent plant with genotype ggPp would form two types of gametes in 1:1 ratio= gP and gp. The random fusion of these gametes from two parents would obtain progeny in the following phenotype ratio=

1/4 yellow purple: 1/4 yellow white: 1/4 green purple: 1/4 green white  

Therefore, 1/4 of the total progeny would be "yellow and white".

explanation:

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
