Evgen [1.6K]

Upon crossing BB with bb, we will get a hybrid of Bb.

  • Codominance is a phenomena in genetics where two alleles (different forms of the same gene) express themselves equally in an organism. As a result, characteristics linked to each allele are shown at the same time.
  • The MN blood group system in humans is an illustration of codominance. M and N alleles control the MN blood type. Red blood cells from people who are homozygous for the M allele carry a surface molecule known as the M antigen. On their red blood cells, those who are homozygous for the N allele contain the N antigen. A heterozygote is a person who carries both antigens.
  • (a) Genotype of blue scales fish will be BB.
  • (b) Genotype of blue scales fish will be bb.
  • (c) Genotype of blue scales fish will be Bb.

So, in this case B and b alleles will express equally.
