Bear pigmentation is subject to epistasis of the B alleles by the d alleles. B (black) is dominant over b (brown). D is dominant

White raven [17]

Answer:

9/16 black, 3/16 brown, 4/16 white

Explanation:

BD Bd bD bd

BD BBDD BBDd BbDD BbDd

Bd BBDd BBdd BbDd Bbdd

bD BbDD BbDd bbDD bbDd

bd BbDd Bbdd bbDd bbdd

A punnet square can be described as a diagram which is made to predict the genotype as well as the phenotypes of the offsprings of a cross.

To study the epistatis nature of the pigmentation in bear, a punnet square was made and the results of the punnet square are shown above.

The results of the punnet square show that the cross between two bears will have the chances of producing 9/16 black bears, 3/16 brown bears and 4/16 white bears.

You are analyzing a human pedigree for a new disease and discover that the disease occurs with the same frequency in both sexes

Natasha_Volkova [10]

Answer:

The correct answer is A. autosomal recessive

Explanation:

In an autosomal disease, the mutation occurs in the autosomal chromosome, not in the sex chromosome. In autosomal recessive disease if both the defected allele from parent comes in the child then only the child would be affected by the disease. If the offspring have single defected allele than he is said to be a carrier.

So as the defect is not in sex chromosome the disease will occur in the same frequency in both the sexes and if parents are carriers which means they are not affected by disease than 25% offspring can have the disease because out of four offspring one can get both the defected allele, one from each parent. So the correct answer is A.

Classify the following gas planets as terrestrial planets or gas giants

kkurt [141]

<h2>Answer:</h2><h3>Part 1.</h3><h3> Celestial body A is the largest planet in the solar system.</h3>

It is Jupiter which is a <u>Gas giants.</u>

Jupiter is mostly made of gas.

According to above statement, It is the Jupiter which largest planet in our solar system. Jupiter's mass is more than 300 times that of Earth, and its diameter, d, at 140,000 km.

<h3>Part 2. </h3><h3>Celestial body C has optimum conditions to sustain life.</h3>

It is earth which is a<u> terrestrial planet.</u>
Because it is mostly made of silicate rocks and minerals.

According to statement, earth is that planet because it has living optimum conditions. Like the oxygen concentration, water, plants etc.

Celestial body E has the most volcanoes in our solar system apart from earth. It is the second closest planet to the sun.

It is Venus and it is a<u> terrestrial planet.</u>

Venus orbits sun every 224.7 Earth days.

It has the longest rotation period of any planet and it rotates in opposite direction to most of the planets in the Solar System.

<h3>Part 4.</h3><h3>Celestial body H is the second largest planet in the solar system and has visible rings.</h3>

It is Saturn which is a <u>gas giant.</u>
Because it is mostly consists of gases and it also has ring of gases around itself.

it is 9.4 times as large as the Earth. It also has a large and bright ring system.

<h3>Part 5.</h3><h3>Celestial body D has 17 times more mass than earth and has gravity that is 1.14 times that of earth. </h3>

It is Neptune and it is a <u>gas giant</u>.
It has mostly gaseous composition, such as hydrogen and helium.

Neptune is the eighth and farthest known planet of the Solar System. It is also the third most massive planet.

<h3>Part 6.</h3><h3>Celestial body G has a core that consists of iron sulfide mixed with nickel and is the second smallest planet in the solar system.</h3>

It is mars and it is a<u> terrestrial planet</u>.
Mars is the second smallest planet while mercury is first smallest planet after the exclusion of Pluto from solar system.

The surface of mars is covered by talcum powder type dust. It contains elements besides silicon and oxygen, are iron, magnesium, aluminum, calcium, and potassium.

<h3>Part 7.</h3><h3>Celestial body I had a core composed of nickel iron alloy rock surrounded by an outer layer of hot fluid. The fluid contains water, ammonia, and methane body I has 27 moons .</h3>

This is Uranus and it is a<u> gas giant</u>.
is the seventh planet of the Solar System.

According to radius, it is on third number and according to mass it is forth largest planet. Its composition is more similar to Neptune.
