Can you please help me!? ​
monitta

Answer:

You need to compare the location of bands for X and X's child. X is the mother, so the child will have half of all its bands from its mother, and the other half must be from the father. Some bands that X and X's child have in common are at around 185bp and 130bp (it is difficult for me to determine the exact position). Then look at the bands which X and X's child do not have in common. Those bands must have come from the father. So now you compare the remaining bands to all the bands of Megabucks and see if they match up. You can see a band at around 60bp that the child has. The mother did not have this band, so it must have come from the father. Megabucks does not have this band, so he is not X's father.

Explanation:

I hope this has helped you a little. The main thing to know is that a child's bands come from their mother and father, so if half the bands match up to the mum, the other half have to match up to some of the father's bands. But a child will never have the same set of bands as one of their parents - it will be a mix of both parents' bands.

Animal regeneration can produce whole organism or parts of organism and repair injury.

Clones today are done at genetic level by using molecular biology techniques as compared to old days when only nucleus would be removed from the egg cell and desired nucleus is inserted for cloning.

Explanation:

Regeneration is a process in which whole organism or part of which is produced from pre existing cells or group of cells and tissue. Regeneration helps in maintaining the integrity of morphology and physiology.

In lower animals like hydra and planaria whole organism is generated by existing parts. This process is termed as totipotency.

In higher animals however injury repair by mitosis is an example of regeneration.

Plant structure involved in vegetative propagation are: bulbs, rhizomes and tubers.

Vegetative propagation can be done by grafting, cutting, bulb formation, tuber, layering and tissue culture methods.

Cloning is a process in which a genetical or identical copy of an organism or the cell is made by molecular biology techniques. The use of DNA sequences, molecular scissors, stem cells and plasmid are the latest techniques of cloning.

Cloning is used for treating serious diseases as diabetes and heart injury.

In old days one cell would have its nucleus removed and placed into the egg and eventually organism produced

Advantages of tissue culture:

From a single explants, large number of plants can be made.

Obtaining plants of desired trait from tissue culture is easy in short span.

No seeds are required for the growing of new plants.
