The answer is rr because if it were "Rr" it would be round. Dominant always exceeds the recessive. so if both traits were recessive, it would be recessive. so "rr" is your answer

<u>Answer</u>: rr

<u>Explanation</u>:

  • For any given gene there exists two or more variant forms known as the alleles.
  • The allele can either be dominant or recessive.
  • A dominant allele is the one which determines the phenotype in both heterozygous and homozygous condition whereas the recessive phenotype is only shown in case of a homozygous condition.
  • Since the trait of wrinkled seeds is determined by a recessive allele, it is necessary for the allele r to be present in homozygous condition
  • <em>Therefore the genotype should be rr.</em>

leva [86]

Answer:

Each is a mini-ecosystems and a representation of much larger ecosystems found on earth. The mini ecosystem is the terrarium

Explanation:

A terrarium is the accumulation of small plants that are being grown in the transparent, or sealed container. It is a closed environment type and are mostly used to know how the ecosystem works within itself. Inside that small container, we can observe various natural processes like photosynthesis, respiration, as well as water cycle. Some small plants cannot adapt well in the home environment, so they can be grown in the terrarium. If they are properly planted and taken care of they can grow with minimum care. By this we can grow indoor plants with less care.
