what is a roan color in cattle is controlled by codominant genes for both red and white hair. if a roan cow is crossed with a white bull, what percentof offspring would be white?

50%

Explanation:

Roan color is controlled by two codominant alleles. Let us assume that the red color allele is R and the white color allele is W. Thus, the roan color would be RW.

Roan color cow is crossed with a white bull;

    RW   x   WW

RW   RW   WW   WW

RW = roan = 50%

WW = white = 50%

1/2 or 50% of the offspring would be roan color while the remaining 1/2 or 50% would be white in color.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
