1. Incomplete dominance has occurred

2. A phenotypic ratio 1 Blue : 2 pale blue : 1 white will be obtained.

Explanation:

Mendelian principle states that one allele is capable of masking the expression of another i.e. one allele is dominant and the other one is recessive. Genetic scenarios that have gone against this principle has been observed. One of them is the concept of INCOMPLETE DOMINANCE, which is a case where one allele is not completely dominant over the other, hence, they combine to form a third intermediate phenotype different from both parents.

This is the case in the question where the the blue allele (B) fails to completely dominate the white allele (W), instead it forms an heterozygous plant (BW) with a different phenotype (pale blue) that is a blending of the two parental phenotypes (blue and white). This heterozygote (BW) is formed in the F1 generation.

If the F1 offsprings (BW) are self-crossed, four possible offsprings will be produced using a punnet square. This offsprings will have genotypes: BB, BW, BW, and WW. This depicts a genotypic and phenotypic ratio of 1:2:1 i.e. 1 blue (BB) : 2 pale blue (BW) : 1 white (WW).

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
