9. In guinea pigs, rough coat is dominant (R) to smooth coat (r) and black coat (B) is dominant to white coat (b). A rough black
lisabon 2012 [21]

Answer:

the genotype of the parent guinea pigs are as follows:

RrBb (rough, black) and Rrbb (rough, white)

Explanation:

Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.

After making the dihybdrid cross, the probability obtained for each phenotype is given below:

rough black: \frac{3}{8}

rough white: \frac{3}{8}

smooth black: \frac{1}{8}

smooth white: \frac{1}{8}

Hope that answers the question, have a great day!

How does an area's weather differ from the area's climate?
DerKrebs [107]

C

Weather is the day-to-day changes in the atmospheric conditions of  regions. Weather parameters are usually temperatures, humidity, rainfall, air pressure, and etcetera. These vary greatly every so often on a daily basis. Climate, on the other hand is categories into arctic, subarctic, subterranean, Mediterranean, temperature, equatorial, and etcetera.

Explanation:

When weather is studied for a long time, such as for over 30 years, general weather patterns can be discerned that will determine the climate of the region. These general weather patterns over a region will make up its climate. Climate does not change considerably. Therefore the climate of a region remains steady. If the climate of a region changes it does so ever so slightly over millennia  and would change because of phenomena like earth’s tectonic plate movements, space phenomenons, and human activities.

Jenny is trying to describe a wave. Which example would be the best description?
hoa [83]
<span>I believe the answer would be B - the toy car would hit another toy car that would in turn hit another toy car, and so on. A wave has a ripple effect, so it will continue to happen down the line, until there is a force that stops it, or there are no more cars to hit.</span>
