This all depends on if you breed the Homozygous form of the Co-dom or the Heterozygous
But
recessive x recessive = all visual recessive (assuming your meaning the Homozygous form of the recessive gene)
recessive x dominant = Het's 50% of which are normal looking and 50% of which look like the dominant gene (assuming your meaning the Homozygous form of the recessive gene and the statics on the dominate gene play out right)
