They have 3 parts in the human brain.
Answer:
5. 100% of the F1 plants will have flowers with no dots.
Explanation:
When a gene is haploinsufficient, the wild type allele needs to be present in two copies to produce the phenotype. In heterozygous condition, the phenotype wont be produced even though one wild type allele is present. The product produced by single wild type allele is insufficient to produce the phenotype.
Here, gene A is haploinsufficient. Wild type allele A1 will produce flowers with dots when it is in two copies. Null allele A2 and mutant allele A3 wont produce flowers with dots. If a wild type (A1A1) is crossed with A2A3 :
A1 A1
A2 A1A2 A1A2
A3 A1A3 A1A3
Since all the plants in F1 progeny have only one wild type A1 allele, its product will be insufficient to produce dots pattern. 100% of the plants will have flowers with no dots.
The correct answer is an Arachnid.
<h2>Answer:</h2>
That's the protein in red blood cells that carries oxygen to the tissues of the body. So, sickle cell disease interferes with the delivery of oxygen to the tissues. Red blood cells with normal hemoglobin are smooth, disk-shaped, and flexible, like doughnuts without holes. They can move through the blood vessels easily.
So, due to change in the structure of protein, cells are not able to do their work properly. It means that protein structure is very important for its proper functioning and functioning of the cell.
