A yellow female Labrador retriever was mated with a brown male. Half of the puppies were brown, and half were yellow. Explain ho
Over [174]

Answer:

The first male was bb Ee, and the second male was bb EE.

Explanation:

In Labradors coat colour is controlled by two genes. Suppose the two genes are B and E. B produces black colour and recessive form bb gives brown colour. Gene E is epistatic over gene B in its recessive form which means that ee will produce yellow colour regardless of the genotype present of B gene.

The first case is possible if the female lab is bbee (yellow) and the male lab is bbEe (brown):

bbee X bbEe

        bE      be

be  bbEe    bbee

So half of the offspring will be brown (bbEe) and half of them will be yellow (bbee)

The second case is possible if the same female bbee mates with a brown male of different genotype which can be bbEE:

bbee X bbEE

         bE

be   bbEe

So all offspring will be brown (bbEe)

Hence, the first male was bbEe and the second male was bbEE.

This is a DNA mutation that does not result in a change to the amino acid sequence of a protein.
ohaa [14]

Answer: silence point

A silent point mutation may be an effect of a base-pair substitution (substitution of one base pair with another in DNA). However, silent point mutations are a special case where no amino acids are affected. As a result, since the monomers of proteins are amino acids, there is no change to the sequence of a protein.

These waves are traveling at the same speed. Which wave has the highest frequency?
Dmitry [639]

Wave of option A has the highest frequency.

Option A.

<h3><u>Explanation:</u></h3>

Frequency is defined as the total number of complete waves in an unit time. A complete wave consists of a complete cycle of the amplitudes of waves.

In all the figures, we see transverse waves. They have the mean position denoted by a straight line, and the waves do oscillate up and down to complete a full cycle. The most number of waves in a given time has the highest frequency. If we count the full number of waves in the particular given time, Wave A has 5.75 complete waves, wave B has 3.5 complete waves, wave C has 2 complete waves and the wave D has 2.75 complete waves. So the wave A has highest number of complete oscillations in a given time. So wave A has highest frequency.
