Anita thinks that she has heterozygous alleles for red hair. if she is correct, which of these diagrams best illustrates anita’s alleles for red hair?

a. r > < r

b. r > < r

c. r >

d. r > < r

The correct answer is- B) Rr

Heterozygous  genotype means both the alleles ( alternative form of a gene) are different ( such as Tt for tall height).

Out of the two alleles in the heterozygous state, one with capital letter depicts dominant allele and the other with small letter depicts recessive allele, which is masked by the presence of dominant allele in the genotype.

As per the question, Anita thinks that she has heterozygous allele for red hair.

This condition is only fulfilled by option B) Rr ( heterozygous genotype), which contains two different alleles that is R and r.

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
