Answer:
Explanation
Water in a lake freezes from the bottom up, killing most aquatic organisms. When water in a lake freezes, it floats, providing insulation for organisms below. ... If water were most dense as a solid, lakes would freeze from the bottom up, eventually freezing solid.
9:3:3:1 is the ratio.
From the given data,
We have a 9.8 two, ratio since we have 49/5, 15/5, 18/5, and 5/5.
This ratio resembles nine a little bit, which is what we inferred from the opposition's score.
When the two relevant genes exhibit independent assortment, this is the result. Therefore, the chromosomes/genes are not connected.
We are finally getting a ratio of 9:3:3:1
In flies, two possible outcomes for the body color phenotype is black and brown.
Whereas in eye color we have white eye and red eye.
Here, white eye is recessive and red eye is dominant
<h3>What does the independent assortment law entail? </h3>
- According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes.
- In other words, an allele for one gene does not affect the allele for another gene that a gamete acquires.
<h3>Where can I find independent assortment?</h3>
- Meiosis I of gamete production, when homologous pairs line up in random orientations at the center of the cell as they prepare to split, provides the physical foundation for the law of independent assortment.

Answer:
Totipotential.
Explanation:
There are different cell potencies. A <u>totipotent</u> cell is a stem cell that can divide itself and <u>differentiate in any cell </u>that the organism needs. That is to say, endodermal cells, ectodermal cells, mesodermal cells, or extra-embryonic tissues. As cells differentiate themselves, they can gradually lose their potential. The cell's category that follows is pluripotent cells. These are stem cells that can only differentiate into ectoderm cells, endoderm cells, or mesoderm cells. Then we have multipotent cells, which differentiate into tissue cells. The next category is oligopotent cells. They give a limited number of specific cells, and lastly unipotent cells, only differentiate in one type of cell.
A person with this genetic disorder has an extra x-chromosome. Their genotype is XXY.
Answer:
1. 0% of probability, 2. 50% of probability, 3. 75% of probability.
Explanation:
In order to find the probabilities we have to draw Punnet squares. The mutated gene will be symbolized with a *.
1. Male CC with female CC, there is no mutation, the probability will be 0%.
X Y
X ║ XX ║ XY
X ║ XX ║ XY
2. The male has not got a mutation and the female has. When we draw the Punnet square, with one female X mutated, we find that there is a 50% of probability of mutation.
X Y
X* ║ X*X ║ X*Y
X ║ XX ║ XY
3. Now both, the female and the male, has the mutation. When we draw the Punnet square with mutations in the female and in the male, we find that there is a 75% of probability of mutation.
X* Y
X* ║ X*X* ║ X*Y
X ║ XX* ║ XY
