Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.

Answers

Answer:

The correct answer is -

Phenotype: 3:1 (dominant black mice: recessive brown allele)

genotype: 1:2:1 (purebred dominant : heterozygous: purebred recessive)

Explanation:

In the given question there is a cross that takes place between two heterozygous black mice. LEt assumes B is black which is the dominant allele and b is the recessive allele or brown. As it is given in heterozygous condition black mice are present which means the B is dominant over b.

Now cross:

Gametes: B and b for each mice

      B        b

B     BB      Bb

b    Bb       bb

By the cross, there are two phenotypic offspring that produce 3 black mice out of four and 1 brown or recessive allele out of four

And, genotypically three offspring in the ratio of 1:2:1 (purebred dominant : heterozygous: purebred recessive)

. The small fish are not affected by the pesticide, but death occurs in the bird, at the top of the food chain. Why do you think that happens?

Answers


Small fish absorb minute amounts of pesticides.

The birds of prey consume many fish to satisfy their dietary needs. The pesticides accumulate and concentrate in the bird, continued exposure overwhelm the predator.

your skin is made up of two layers the epidermis and the dermis. The epidermis produces an oily protein that repels water. When you soak in the bathtub for a long time or Swim for a long time the protein is sloughed off. As a result, your skin cells begin to swell from the excess water and they look wrinkled.

A helpful shortcut our brain makes in scene recognition is to assume that lighting comes from:

Answers

Answer: A. Above

Explanation:

Scientists believe that in order for humans to see things, the brain has to make certain assumptions which are done based on previous scenes that it has interpreted before because the eyes do not provide it with complete data. .

One of those assumptions is that light comes from above which is why the shape of a picture can change depending on the lighting in it.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.

Answers

Answer:

Phenotype: 3 black mice: 1 brown mice

Genotype: 1 BB: 2Bb: 1bb

Explanation:

This question involves a single gene coding for fur color in mice. The allele for black color (B) is dominant over the allele for brown mice (b). This means that a mouse that is heterozygous will be black.

If two heterozygous black parents are crossed i.e Bb × Bb, the gametes produced by each parent are: B and b. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:

BB, Bb, Bb, and bb

- The phenotypes of this cross is  3 black mice: 1 brown mice

- The genotypes of the cross is 1 BB: 2Bb: 1bb
