Explanation:
both IA and IB are dominant- A and B groups show co-dominance
Inheritance describes the way in which certain traits are passed onto offspring of sexual reproduction. For co-dominance, both of a gene's alleles are present, and notable in the phenotype.
Blood glycoprotein alleles are crucial to blood type determination for the ABO system in humans- i does not lead to modifications, while IA leads to the modification of adding N-acetylgalactosamine to the H-antigen on red blood cells; and IB adds galactose
= blood type AB while
= blood type A while
= blood type B. Since
are both dominant over ii, those with that allele have blood type O.
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.
