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
Channel proteins, also known as transport proteins, allow the passage of molecules in and out of the plasma membrane.
A, the independent variable is the thing you change, the dependent is the variable you measure.
I would say physical though.
Your breathing rate goes up when you exercise and slows down when you sleep.
