The combination processes that can transform a metamorphic rock into sediment are the following;
• Exposure – this is the process where the material is being exposed in weathering conditions and it changes its appearance as time passes by.
• Weathering – this is the process in which the minerals, rocks or soil are being break down with the association of it with the earth’s atmosphere.
• Erosion – this is the action in which is where the rocks, soil or material are being removed and are being relocated into another location.

In holstein cattle, the allele for black hair color (b) is dominant over the allele for red hair color (b), and the allele for p

ELEN [110]

I hope you meant, a cross between BbPp and BbPp, else for bbpp x bbpp, all the progeny will be bbpp.

We need to work out a Punnett square to determine the genotypes resulting from the cross between BbPp and BbPp. The dyhybrid cross results in 16 different genotypes, of which a few have the same phenotypes.

It can be seen that there are 4 different kinds of phenotypes present, in the ratio 9:3:3:1.
