B) Cc

C) CC or cc

D) CC or Cc

Answers

Answer: Option A) cc

Explanation:

  • For a given gene, there are 2 or more alternative forms present, and they are known as alleles.
  • The alleles are of two types - dominant and recessive.
  • The dominant allele is the one which expresses itself in both heterozygous and homozygous condition in the phenotype.
  • The recessive allele is the one which is only able to express itself in homozygous condition.
  • Since, the right thumb over left allele c is recessive, the person who crosses right thumb over left must be a homozygote, and hence his genotype should be cc.
