Answer:
1/64
Explanation:
<em>The probability of the offspring being homozygous dominant for the three alleles is 1/64.</em>
Since the three characters assort independently, the probability of the offspring being homozygous dominant for all the three traits is an independent event.
For independent events, the probability of all the events happening together is the multiplication of individual event's probability.
For a cross involving two heterozygotes, taking tall/dwarf for example:
Tt x Tt = TT, 2Tt, tt
The probability of obtaining a homozygous dominant genotype is 1/4.
Hence, the probability of the offspring being homozygous dominant for the three alleles will be:
1/4 x 1/4 x 1/4 = 1/64
Ssris alleviate symptoms of depression by increasing the<u> level of serotonin at the synapse
.</u>
Answer: Option C
<u>Explanation:</u>
Ssris (Selective serotonin re-uptake inhibitor) is a drug that is been prescribed to the people with depression and anxiety disorders. In the brain the information and messages are passed from one nerve cell to the other.
People with disorders find difficulty in transmitting the information. Hence a drug like SSRI's are prescribed to increase the level of serotonin at the synapse as the nerve cell passes the information through synapse the small gap between the cells.
DNA fingerprinting is used to analyze the DNA sample and identify the criminal. The DNA has a set of the portion, which is different in all unrelated people, and this is unique to every person. This is used as a fingerprint and is used to identify a person, in a crime scene.
Explanation:
when the red blood cells are placed in the water, differences in concentration causes haemolysis to occur at a point,excess pressure in the cell on cell membrane causes the cell to burst, diffusion then takes places causing the molecules of the red blood cells to be distributed evenly throughout the distilled water
Does should be do. Thanks have a great day.
