If black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be ind
ludmilkaskok [199]

Answer:

Option B, Co-dominance

Explanation:

This is an example of codominance inheritance pattern.

When two alleles representing two different characteristic traits are expressed equally in the offsprings resulting from a cross, then this genetic inheritance pattern is called as codominance .

For example -

A red flower with genotype "RR" is crossed with a white flower "rr" resulting into pink color offsrping with genotype "Rr"

Here, both the red and white traits of flower color are expressed equally thereby giving pink color to the offspring flower.

The same thing is happening in case of true breeding black and white mice.

Hence, option B is correct

Why is the ability of the cell membrane to be "picky" important?
Yuliya22 [10]

Answer:

Hi there!

Your answer is:

It is very important for the cell membrane to be <em>semi-permeable</em> because the ability to pick and choose what comes in and out of the cell keeps the cell safe! The membrane can choose to block out nasty germs and can also choose to get rid of internal waste.

An example of when this is important is in this scenario:

Let's say the cells are in a really salty solution. Naturally, salt will want to pull the water out of the cell. If the membrane <u>wasn't</u><u> </u> semi permeable, the water would listen to the salt and leave the cell. This would cause cell death. <u>BECAU</u><u>SE</u> the membrane is semi permeable, they can choose <em>not</em> to give the salt any water, keeping them alive

Hope this helps
