Which type of mutation does the model demonstrate?

inessss [21]

Answer:

The bottleneck effect, also known as a population bottleneck, is when a species goes through a "bottleneck" event that suddenly significantly reduces its population. ... The bottleneck effect is a type of genetic drift, which is defined as a random change in allele frequencies.

Which type of phagocytic disorder (formerly known as Job syndrome) occurs when white blood cells cannot initiate an inflammatory

Ber [7]

Answer:

Hyperimmunoglobulinemia E Syndrome

Explanation:

Hyperimmunoglobulinemia E Syndrome or Job syndrome is an immunodeficiency disorder in which the white blood cells are incapable of producing an inflammatory response to infectious organisms. It is an autosomal dominant disorder. It is characterized by recurring bacterial infections, specially of lung and skin. There are also other symptoms like abromalities in vascular or skeletal system and elevated IgE level.

Symptoms like frequent formation of pus pockets in skin, lungs or joints usually begin during infancy. These pus pockets are formed due to infection by staphylococcal bacteria. Treatment usually consists of antibiotics to fight infection and anti histamines to relieve the symptoms like rash and itching. Sometimes drugs can also be administered to modify immune system.

In one or two sentences, identify a change (either increase or decrease) in supply or demand that would cause the equilibrium pr

Contact [7]

A supply curve is a graph that show the number of goods that a producer supply at a certain price at a given point in time. A decrease in supply will cause the equilibrium price to increase. When there is a decrease in supply, the price of the product in the market will increase and the equilibrium price will also increase.

A corn plant known to be heterozygous at three loci is testcrossed. The progeny phenotypes and numbers are as follows:+ + + 455a

astraxan [27]

Answer:

The progeny phenotypes and numbers are as follows:

+ + + 455-------- parental

a b c 470-------- parental

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

+ b + 460---------- parental

a + c 475----------- parental

Total 2,000

+ + + 455-------- parental

a b c 470-------- parental

+ b + 460---------- parental

a + c 475----------- parental

It is two point testcross

So the parental ++ (455+460); ac (470+475)------------------++/ac

Gene order is ------------- ++/ac

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

sum of recombinants--------------140

Frequency of recombintion= recombinants/total x100

Map distances between a-c = (140/2000) x 100 = 7 mu

a------------------7 mu -----------------c
