Answer:

Communication is the important phenomena that helps in the interaction between the people. Communication can be done in the form of language, signs and gestures.

The communication gap between the parents and children might creates a problem in their relationship. The parents should talk politely with their children if they do not want to talk with them. The parents should start communication with the topics in which their children are also interested. They should ask them about the children daily routine and their friends.

Answer:

D. The enteric nervous system will slow down digestion to conserve energy.

Explanation:

The enteric nervous system is like the digestive system's very own brain. It controls the way the digestive system functions. In a fight or flight response, the enteric system slows down the digestive system, this is to make sure that the body has enough energy to course through our muscles and brain to prepare for a "fight" or "flight."

Answer:

The most likely genotype of the male parent is RrBbmm.

Explanation:

First of all, we have 3 genes and 6 alleles:

For color pattern:

- RR or Rr: Solid tail color

- rr: Spotted tail

For coat color:

- BB or Bb: Black coat color

- bb: Brown color

Expression of gene B/b depends on M:

- MM or Mm: B/b is expresed.

- mm: B/b is not expresed, yellow coat.

So, a cross between a solid yellow-tailed male and a solid brown-tailed female was made, and the offspring was:

- 6 solid yellow

- 2 spotted yellow

- 3 solid black

- 1 spotted black

- 3 solid brown

- 1 spotted brown

Total: 16

If it was produced all possible phenotypes, it means that parents have to be carriers of R/r, B/b, and M/m alleles. Male parent is yellow, so he has to be mm for this gene, but for the two other alleles he should be heterozygous:

RrBbmm

And female parent is solid brown-tailed, so she has M allele, (probably heterozygous), and Rr and bb (color brown),, like this:

RrbbMm

When these two genotypes are crossed, 8 gametes are generated for each parent, and 64 possible combinations. This cross in the attached Punnett Square.

As a result, the phenotypicial ratios are in the attached table and they are the same as the reported in the question:

Punnett Square

- 24 (6) solid yellow

- 8 (2) spotted yellow

- 12 (3) solid black

- 4 (1) spotted black

- 12 (3) solid brown

- 4 (1) spotted brown

Total: 64
