<h2>Peptidoglycan Cell Wall </h2>

Explanation:

A cell wall containing peptidoglycan and distinctive ribosomes
Bacterial cell dividers are made of peptidoglycan (additionally called murein), which is produced using polysaccharide chains cross-connected by irregular peptides containing D-amino acids
Gram-positive microscopic organisms have a thick cell divider containing numerous layers of peptidoglycan and teichoic acids
Ribosomes are small particles which is related proteins that capacity to synthesize proteins and comprising of RNA
Proteins are needed for many cellular capacities, for example, directing chemical procedures and repairing damage
Ribosomes can be discovered drifting inside the appended to the endoplasmic reticulum or cytoplasm

Answer:

If the genotype of the parents are Iᵃi and Iᵇi, then four type of offspring will be produced.The genotype of the offspring are, IᵃIᵇ, Iᵃi,Iᵇi, and ii.

Explanation:

IᵃIᵇ = As the alleles are co-dominant in nature, so both type of alleles are expressed. The blood group will be AB. So, both A and B type of antigen will be found in plasma membrane of RBC.

Iᵃi= In this type of genotype only A type of antigen will be expressed in the membrane of RBC. The blood group will be A type.

Iᵇi= In this type of genotype only B type of antigen will be expressed in the membrane of RBC. The blood group will be B type.

ii= This is a recessive type of genotype. So, no antigen will be found on the membrane of the RBC. And the blood group will be O type.

The offspring's ratio will be 1:1:1:1.
