Assume that a cross is made between AaBb and aabb plants and that the offspring occur in the following numbers: 106 AaBb, 48 Aab
Elenna [48]

Answer:

linkage with approximately 33 map units between the two gene loci

Explanation:

If two genes are not linked, number of recombinants and parental offspring will be equal. Here it is clearly visible that recombinants are less than parental offspring hence the genes are linked. Given, the offspring are in following numbers:

AaBb = 106 = Parental

aabb = 94 = Parental

Aabb = 48 = Recombinant

aaBb = 52 = Recombinant

Recombination frequency = (Number of recombinants/ Total progeny) * 100 = (100/300) * 100 = 33.33 %

1% recombination frequency= 1 map unit of distance between the two gene loci. So here the distance between the two gene loci is approximately 33 map units.

Hence, these results are consistent with linkage with approximately 33 map units between the two gene loci

larisa [96]

Answer:

The three basic items to make an electromagnet are a source of current, conducting wire, and a metallic core. Electromagnetic is a type of magnet which is formed with the help of electricity.

When the current is allowed to pass through the wire and the metallic core, the magnetic field is generated around the metallic core and when the current is turned off, the metallic core losses the property of magnetism.
