The roan coat color in cattle is an example of codominance. This means both alleles are clearly expressed.

If a white cow is crossed with a red cow, the offspring will have a coat made of both red and white hairs.

1. If two roan cattle were crossed, what percent of the offspring would you expect to have a roan coat?

50 % of the offspring are expected to have roan coat If two roan cattle were crossed.

Explanation:

In codominance both alleles from the parents are expressed and the phenotype is different from the parents.

Roan is a type of coat colour where there is even occurrence of coloured and white hairs on the coat of the cattle.

The genotype of Roan cattle is CRCW  (CR red, CW-white)

If two roan cattles are mated:

CRCW X CRCW

punnet square shows:

       CR       CW

CR CRCR    CWCR              the genotype ratio = 1:2:1

CW  CWCR  CWCW            phenotype ratio = 1:2:1

1  pure white cattle

1 pure red cattle

2 roan cattle

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.
