Answer #1

Question

1. The hemoglobin binding with oxygen show cooperative binding. This is because when oxygen bind to one subunit of oxygen it increases the affinity of oxygen to the hemoglobin. Hence option c is correct.

2. If both parents are the carrier of the disease then it is 25 chance of getting this disease in the offspring. Hence option a is correct.

Allele “A” is the normal form of the gene and codes for a part of the protein complex called hemoglobin. Hemoglobin is required for your blood cells to carry oxygen. Allele “a” is an abnormal form of the gene. The hemoglobin protein made from the “a” allele is defective. Red blood cells containing the defective protein are very fragile. This disease is recessive–meaning...

    On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky...
