The white-tailed deer, odocoileus virginianus, is common in the eastern united states. most deer have reddish brown fur, but occasionally a deer may be born with a genetic condition known as albinism which results in white fur. albinism is caused by the inheritance of two recessive alleles for the production of coloration pigments. if an albino deer is born to two parents who each have normal fur coloration, what conclusion may be drawn about the genotypes of the parent deer?

Both the parents must be the carrier of recessive genes along with dominant gene

Explanation:

Recessive genes are genes that are expressed only when two recessive alleles are inherited from the parents.

A dominant gene is expressed in two cases a) when two dominant alleles are inherited or b) when one dominant and one recessive allele are inherited.

since parents have normal fur color but they are producing white fur coloured deer  (Albinitic offsprings)  this means that both of the parents must be the carrier of recessive genes.

Let the allele for “normal fur colour” be expressed by C

Allele for “white fur color” be expressed by c.  

Both the parents have heterozygous dominant gene (which is carrier if recessive allele "c"), thus their genotype would be Cc

Let see the punnet square below -

cCccc

Out of the four offspring’s produced only  “cc” represents white fur deer.  

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
