Answer:

The correct answer is 1. EEG.

EEG or electroencephalography is a technique used to measure the electrical activity of the brain.

8 to 16 pairs of electrodes are placed on the scalp which record the electrical activity or impulses (in volts) generated by thousands of neurons or nerve cells present in the brain.

It provides the real-time imaging of the electrical activity of the brain.

The recorded impulses are first sent to the amplifier as the magnitude of the brain's electrical impulses is very low.

The amplifier then amplifies the results and show it on the screen in the form of voltage units.

Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if both dogs are heterozygous (Ll)
Brut [27]

Answer:

75% would have the dominant traits for coat length, 25% would have recessive trait for coat length.

Explanation:

After completing a punnet square, we could find that our genotypes are 25% LL, 50% Ll, and 25% ll.

If these genotypes were to be physically expressed, LL and Ll would both be expressed as showing the dominant trait.

This means that 75% would have the dominant traits for coat length and 25% would have recessive trait for coat length.

I hope this was helpful! Let me know if you need any clarity.
