If grey feathers is a recessive trait, then 72.8% of the population is heterozygous for this trait.
Explanation:
The concept used here is of Hardy Weinberg principle, 
+2pq =1
The homozygous dominant genotypeis represented as 
= 84
Red = dominant
The homozygous recessive genotype trait is represented as 
= 16
grey = recessive
2pq = heterozygous individual
Thus for dominant homozygous the alleles are given as
p= 
= 9.1
q = 
= 4
for heterozygous individual 2pq
2 x 9.1 x 4
= 72.8
72.8% population is heterozygous for the trait.

Thyroid gland is an endocrine gland that is found in front of the neck, it consists of two lobes connected by isthimus. It is in front of the neck lying against and around the front of larynx and trachea. Thyroid gland secretes three hormones which are thyroxine, triiodothyronine and calcitonin. Thyroxine and trio doth tribune are thyroid hormone. The parathyroid glands are tiny structures found in the thyroid gland. A thick connective tissue separates the parathyroid glands from thyroid tissues. The thyroid gland is controlled by thyroid stimulating hormone called thyrotropin which is released from the anterior pituitary gland which triggers the release of thyroid hormones.
