Answer:
6 offsprings with white fur
Explanation:
The gene involved here codes for fur colour in mice where the allele for brown fur (B) is dominant over the allele for white fur (b) i.e. the B allele will mask the expression of b allele in an heterozygous state (Bb).
Since allele B is dominant, in an heterozygous state (Bb), the mice will be brown-furred. Hence in a cross between two Bb parents, a phenotypic ratio of 1:2:1 will be produced where;
1 is BB (homozygous brown fur), 2 is Bb (heterozygotic brown fur) and 1 is bb (homozygous white fur).
Hence, 1/4 × 100= 25% offsprings will be white furred. If 24 mice result, 25/100 × 24 = 6 offsprings will be white.
Answer:
Original Remains Fossil
Explanation:
Fossils that are the actual bodies or body parts of organisms are called original remains fossils. A Mold fossil is a fossil formed when complex parts of an organism are trapped in sediment dissolved away leaving behind a hollow area with the organism's shape. A cast fossil is a fossil formed when sediment fills in the hollow space of the shape of an organism. A carbonized fossil is a fossil when a dead organism is compressed over time and the pressure drives out the liquids and gases leaving behind an outline of the organism
Answer:
The concept of immense periods of geological time are necessary to account for the possibility of the small changes resulting slowly into major changes. Thus long periods of time are essential for Darwin's theory of slow uniform biological changes being responsible for the Origin of the Species.
