Chapter 23, Problem 4RQ
Summary Introduction
To determine: The names of different thyroid hormones.
Introduction: Thyroid hormones are produced by the thyroid glands present in the front side of the trachea. The thyroid gland is an endocrine gland, and the secretions are released in the blood to reach the target cells. Iodine is a crucial mineral which is used by the thyroid gland as a precursor to produce thyroid hormones.
Summary Introduction
To determine: The name of the thyroid hormone that has the highest activity.
Introduction: Thyroid hormones are produced by the thyroid glands present in the front side of the trachea. The three different types of hormones produced by the thyroid gland are triiodothyronine (T3), thyroxine (T4), and calcitonin.
Summary Introduction
To determine: The region where thyroid hormone that has the highest activity is mostly produced.
Introduction: Thyroid hormones are produced by the thyroid. The three different types of hormones produced by the thyroid gland are triiodothyronine(T3), thyroxine(T4), and calcitonin. The highest concentration of thyroid hormone produced is T4 almost 80 % of the T4 is produced by the thyroid gland but the highest activity is shown by T3 hormone.

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW). If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?
None
Question #3:
In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would
transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming
there was just one gene conferring gametophytic obligate apomixis, and that the two parents are
inbreds, what would be the consequences of such a cross if:
a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non-
apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic
and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female
first (left side) in the parental cross.
b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non-
apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic
and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female
first (left side) in the…

- Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:arrow_forwarda. What percentage of a drug is eliminated after 4 half-lives?
