In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey

Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM

The combined observations of Matthias Schleiden, Theodor Schwann and Rudolph

kobusy [5.1K]

Answer:

The option 'All cells contain a nucleus' is not a part of the cell theory.

Explanation:

The cell theory proposed by scientists illustrates that every organism whether prokaryotic or eukaryotic is made up of a cell or different kinds of cells. It also that explains that cells are made from living things. According to the cell theory, cells are termed as the basic unit of life, without which life is not possible.

The cell theory does not claim that every cell must have a nucleus because many cells like cells of prokaryotes lack nucleus. Their genetic material is dispersed in the cytoplasm.

Identify the four spheres of the carbon cycle

diamong [38]

The biogeochemical cycle in which carbon is exchanged between Earth's terrestrial biosphere, hydrosphere, geosphere, and atmosphere is called the carbon cycle. The global carbon budget is the balance of the fluxes of carbon between these four reservoirs.

A chronic bone disease that is characterized by the abnormal breakdown of bone followed by abnormal bone formation is known as

Sidana [21]

Answer:

Paget's disease

Explanation:

When cellular deforming and remodelling of many bones takes place and this occurs as a chronic condition then this is known as Paget's disease.
There is excessive breakdown of bone as well as disorganised formation of new bones.
Such problem leads to weakening of the bone due to which complications such as deformity, fracture and arthritis occurs.
The disease does not spread from one bone to another and the entire skeleton is not affected in such a disease, it only affect few or more bones.
There is currently no known cure for the disease.
