In mice, agouti fur is a dominant trait resulting in individual hairs having a light band of pigment on an otherwise dark hair s

haft. A mouse with agouti fur is shown here, along with a mouse with solid color fur, which is the recessive phenotype (A = agouti; a = solid color).
A separate gene, which is not linked to the agouti gene, can result in either a dominant black pigment or a recessive brown pigment (B = black; b = brown).
A litter of mice from the mating of two agouti black parents includes offspring with the following fur colors:___________
a) solid color, black
b) solid color, brown (sometimes called chocolate)
c) agouti black
d) agouti brown (sometimes called cinnamon)

Answer:

The answer is given below

Explanation:

The 2 traits of the agouti fur mice are determined by non linked genes, which assort independently.

For this purpose we will use the multiplication rule to calculate the probability of agouti brown offspring  (A_ bb) from AaBb parents.

The probability of A_ offspring is 3/4 and the probability of offspring bb is 1/4.

The total probability will be 3/4 x 1/4 = 3/16.

A4 kg object possesses 18 J of kinetic energy. What is its velocity?
Digiron [165]

Answer:

velocity = 3 m/s

Explanation:

kinetic energy = 1/2 * mass(kg) * velocity²

Using the formula:

                                     18 = 1/2 * 4 * velocity²

                                      9 = velocity²

                                     velocity = 3 m/s

The main organic source of energy for living things is
neonofarm [45]

Answer:

The Sun

Explanation:

Nearly everything eats sunshine – or eats something else that ate sunshine. The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter.

The clinical manifestation which supports this conclusion is that an injury to the brachial plexus which happens during birth. Erb is termed as a paralysis of the arm which is caused by an injury on upper arm's main nerves to be specifically the C5-C6 nerves.
It arrives most commonly on shoulder dystocia when there is a difficult birth. This paralysis can resolve on its own depending on nature of the damage.

When Mendel crossed a plant homozygous for round seeds to another plant homozygous for wrinkled seeds, he found that all the pro
deff fn [24]

Answer:

a. The allele for round seeds is dominant to the allele for wrinkled seeds.

Explanation:

Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.

A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".
