IRISSAK [1]

Answer:

A) Calcitonin injection

Explanation:

Parafollicular cells or C-cells of the thyroid gland produce a hormone which is involved in the regulation of calcium levels in the blood. This hormone is Calcitonin. It works in an antagonistic manner with the Parathyroid hormone (PTH). Calcitonin decreases the calcium level in the blood by increasing absorption of calcium ions in bones.

In chickens the dominant allele Cr produces the creeper phenotype (having short legs). However, the creeper allele is lethal in
Svetllana [295]

Answer:

66.6% of the living progeny would be creepers

Explanation:

The creeper allele is Cr for both parents this means that there is a 50% chance that they will pass the C or r trait to their progeny. In this scenario the deleterious inheritance of rr will be 25% so this will not be factored in this answer. The other progeny is CC 25% and Cr 50% for genotype only

The new calculation for living progeny is this: Of the chances of three living progeny there could be one normal CC and two creepers Cr. This means that 33.3% of the living progeny is normal CC and 66.6% of the living progeny are creepers Cr.
