What must be the genotype?​

Biology
1 answer:
Sonbull [250]2 years ago
7 0

Answer:

XnY

Explanation:

II-2 is a male so the genotype must have a Y in it. Majority of the other options do not have Y, so they are incorrect. Because the individual is male, the father has passed a Y chromosome, while the mother has passed an X chromosome. The X chromosome is Xn because the mother is hemolytic, which is a recessive trait. So both the mother's X chromosomes carry the hemophilia trait.

What do we mean when we refer to a cell as differentiated?
Otrada [13]

Answer:

We mean that a cell changes to another type of cell.

Explanation:

<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally.

Then, a differentiated cell is a cell that had gone under the previously described process.

Why are manure better than fertilizers​
Irina18 [472]

Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility. On the other hand, fertilisers harm these microbes and cause health issues in the consumers since they are synthesised chemically.
