8 0

Answer:

1 out of 4

or

25%

Explanation:

First we draw a Punnett Square for this:

          R      r

   R    RR    Rr

   r     Rr     rr

So here we have the following genotypes possible for this cross:

RR = homozygous dominant

Rr = heterozygous dominant

rr = homozygous recessive

As you can see out of the four (4) possible outcomes, one (1) of them is rr. So the probability is 1 out of 4 chances or 25%.

Helppppp pls ! I can’t understand this question.
Artist 52 [7]

Answer:

The correct option is D. The nerve and red blood cells will turn on and off different portions of their DNA, using different genes to make different proteins.

Explanation:

A zygote is totipotent which means it has the ability to differentiate into any cell type found in the body along with the placental cells.

The nerve and red blood cells are specialized cells and they cannot differentiate into any other cell type.

All cells in the body are formed from the zygote. All the cells in the body have the same chromosomes and the same genes. However, these cells become specialized because certain part of the DNA is activated in one type of cell which helps it perform its function. Different genes are activated in different specialized cells which are able to transcribe and translate.
