In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr

swat32

The correct answer is optionD 134/200.

The frequency of the dominant allele can be calculated by the summation of the frequency of the homozygous individual frequency that has dominant allele and half of the heterozygous individuals, as half of the heterozygotes have dominant allele.

The frequency is no of individual of desired trait divided by total number of individual.

The calculation is shown below: $frequency of dominant allele=frequency of dominant individual+\frac{1}{2} frequency of heterozygotes\\frequency of dominant allele=\frac{50}{100} +\frac{1}{2} (\frac{34}{100} )\\frequency of dominant allele=\frac{50}{100} +\frac{34}{200} \\frequency of dominant allele=\frac{2(50)+34}{200}\\ frequency of dominant allele=\frac{134}{200}$

Secretion of which hormone is NOT controlled by a negative-feedback mechanism?

dem82 [27]

Hello there,

Your correct answer would be "oxytocin".

This would be your answer because oxytocin is the only hormone that has a positive feedback loop. The other one's do not have positive. They contain negative loop's.

Hope this helps.
