In Holstein cattle the allele for black hair color (B) is dominant over the allele for red hair color (b), and the allele for po
torisob [31]

Answer:

A dominant trait can be described as the one which masks the effect of a recessive trait. The alleles for a recessive trait gets suppressed by the dominant one.

A punnet square can be described as a diagram which depicts the outcomes of a cross. For single traits, the cross is monohybrid. For studying two traits at a time, a dihybrid cross can be made.

The punnet square for the following Holstein cattle can be shown as:

           BP           Bp          bP             bp

BP     BBPP     BBPp     BbPP         BbPp

Bp     BBPp     BBpp     BbPp          Bbpp

bP      BbPP     BbPp     bbPP          bbPp

bp      BbPp      Bbpp     bbPp          bbpp

The results show the phenotypic ratio to be 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned

The replica fossil you just created models the actual formation of fossils on Earth. In your replica, what do the clay and the p
LenaWriter [7]

The making of replicas of the original fossils, is pretty much the say way, just different materials, in which the fossils originally have been formed and preserved.

When an organism dies, be it a plant or an animal, it gets fossilized only if very quickly after the death it is covered with sediments or mud. The sediments or the mud protect the plant or animal from the outside influences, so once it is kind of in a vacuum, or protective layer if you will, in which parts of the plant or animal that are long-lasting are preserved.

The clay and plaster used for the replica, work in the same way, because they wrap around the fossil tightly and isolate it from outside influences, with the result being different though, as they just make a copy of the fossil.
