Replace null values in duplicates

[Anonymous]

If I have a sorted table like below:

Fruit	Colour
Apple	null
Apple	Red
Banana	Yellow
Pear	null

How can I replace the null value in "Colour" with the correct value based on matching values in "Fruit"? The table I would want is:

Fruit	Colour
Apple	Red
Apple	Red
Banana	Yellow
Pear	null

The query I am trying is: 

= Table.ReplaceValue(#"Sorted Rows", null, each [Colour]{List.PositionOf([Fruit],[Fruit], 2)},Replacer.ReplaceValue,{"Colour"})

but this is not working.

= Table.Combine(Table.Group(#"Sorted Rows","Fruit",{"n",each Table.ReplaceValue(_,null,List.Last([Colour]),Replacer.ReplaceValue,{"Colour"})},0)[n])
