A cross between a plant with red flowers (R = dominant) and a plant with white flowers (r = recessive) yielded 47 plants with re

d flowers and 51 plants with white flowers. What are the genotypes of the parent plants? Explain.
A. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the parents are Rr and rr.
B. The results should yield plants with red flowers and plants with white flowers in a 3:1 ratio due, so the geneotype of each parent is Rr. The number of offspring was not large enough to produce the expected results.
C. The results differ from the predicted values. Therefore, the genotypes of the parents cannot be determined.
D. The results should show a ratio of 3 plants with white flowers to 1 plant with red flowers, so the genotypes of the parent plants are RR and rr.

If a cell loses control of gene expression, what happens?
kipiarov [429]

Answer:

Abnormal, unhealthy cells develop

Explanation:

Gene expression is the process through which genes are turned on through transcription, and to some extent through the translation of the mRNA.

Gene expression is highly regulated to ensure the cell can create the correct combination of proteins to carry out it's tasks. If gene expression is out of control, the mRNAs that are transcribed in the cell are not properly regulated, and therefore the proteins in the cell are not regulated. Since proteins carry out essentially every function in the cell, the cell becomes unhealthy, and incorrectly uses its resources.

Accurate control of gene expression also ensures that the cell can perform specialized functions, it is what makes a heart cell distinct from a brain cell, for example. Therefore, if it is out of control, cells will not be specialized correctly.

Biology question 3
mamaluj [8]
The muscle cells divide through Mitosis, a cellular division comprised of several other substeps. 

The final step of the cell division is the cytokinesis by which two new cells are formed from cell with a multiple number of nucleus after the replication process. This steps follow the telophase.

What is biogeography and what does it provide?
Dennis_Churaev [7]

It provide evolution in many ways because organisms are not distributed evenly throughout the world, but related organisms are found in the same isolated parts of the world and this is not explained by climate.
