HELP PLEASE In the following cross, assume simple dominance and independent assortment for each trait. What proportion of the progeny will be expected to phenotypically resemble the second parent? AABB x Aabb

1. 1/4

2. 1/8

3. 3/4

4. 3/8

0

Explanation:

This question involves two genes; A and B. According to the question, two parents are crossed as follows: AABB × Aabb. The parents will produce the following gametes:

AABB- AB, AB, AB, AB

Aabb - Ab, Ab, ab, ab

Using these gametes in a punnet square (see attached image), the offsprings in the following proportion will be produced:

AABb = 4/16 = 1/4

AaBb = 4/16 = 1/4

Therefore, none (0) of the offsprings will resemble the phenotype of the second parent (Aabb).

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
