Answer:

The correct answer is - T4, and T3.

Explanation:

The Thyroid glands are butterfly shape glands madeup of microscopic spherical structures known as thyroid follicles made up of cuboidal follicular cells. These cells produces the both major hormones of thyroid gland T4, and T3.

The majority of thyroid hormones are produced as T4 hormones approximately 80% but a small amount of 20% is released in the form of T3 hormones. However, the most active form of the thyroid hormone is T3 and to act on target cells, one iodine molecule have to be removed to convert T4 to T3.

Dvinal [7]

Answer:

Phenotype genotype Number of individuals

Red RR 245

Pink Rr 210

White rr 45

Number of alleles in total

R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency

r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency

Predict (Hardy Weinberg) genotype frequencies=

p^2 + 2pq + q^2 = 1

p= 0.7

q=0.3

0.49 + 0.42 + 0.9 =1

According Punnett Squares in F1 we have=

Rr* rr = Rr 50% and rr 50%
