The baby would have 22 pairs of chromosome and an another pair that determines its sex. XX will make the baby a female and an XY make it a male. (there are no recessives of these sex alleles, just two different types: X or Y)
Then, the rest of the baby's traits are determined by the alleles each parent contributed for each trait. In complete dominance, one allele is dominant to the other (M=dominant m=recessive) and so the following combinations will express the dominant trait: Mm or MM. If both parents contributed a recessive allele, then the recessive trait will show, e.g. mm) In incomplete dominance, a mix of both alleles will show as a trait (e.g. a white flower and red flower making a pink flower) Finally in co-dominance, BOTH alleles will be expressed. Hope this is the info you were looking for.
