In minks, the alleles b and b determine black and brown fur, respectively. however, the allele q of an unlinked gene is epistatic to the b and b color alleles, resulting in a silver fur (q has no effect on fur color). if animals of genotype b/b; q/q are intercrossed, what phenotypic ratio is expected in the progeny?
organisms can be either producers or consumers in terms of energy flow through an ecosystem. producers convert energy from the environment into carbon bonds, such as those found in the sugar glucose. other producers includebacteria living around deep-sea vents.
the low rate of energy transfer between trophic levels makes decomposers generally more important than producers in terms of energy flow. decomposers process large amounts of organic material and return nutrients to the ecosystem in inorganic form, which are then taken up again by primary producers .
a pattern of energy flow through the organisms that live in any ecosystem can be observed. producers, such as a tree, algae make their own food and begin this cycle. the producers are then eaten by primary consumers that cannot produce their own food, such as a giraffe. they eat the primary consumers . producers bring energyfrom nonliving sources into the community. primary consumers eat th eproducers, which makes them herbivores in most communities .
algae is protist ,carry out ,photosynthesis ,lives in ponds & oceanfound in fresh and salt water environments .can live on rocks, trees, and in soils with enough moisture.can carry on photosynthesis – produce large amount of oxygen .
the answer would be: dominantexplanation
a cross between a true breeding short plant (homozygous for short, suppose tt), and a cross between a true breeding tall plant (homozygous for tallness, suppose tt) would result in all the offspring being heterozygous for the traits, meaning they would each have an allele of shortness (t) and an allele of tallness (t).
considering the offspring were all tall, we understand that the allele for tallness must have been dominant over the allele for shortness to present itself over it. hence, the term describing the gene for tallness would be dominant, and the term describing the gene for shortness would be recessive.
hope this !
