Can recessive genes produce dominant traits

Or vice versa?

First of all, let me use an example to show you.
Let the recessive allele be a and let the dominant allele be A.

To produce recessive trait, the genotype needs to be aa(homozygous recessive)
To produce dominant trait, the genotype needs to be AA (homozygous dominant) or Aa(heterozygous dominant).

To answer your question, I think is no. This is based on the assumption from your question that both genes are recessive. By using punnett square method, the results will be all recessive(aa).

On the other hand, I think that dominant traits can produce recessive gene beacuse dominant traits can carry the genotype of Aa. AA cannot be the genotype of the dominant trait as it will lead to all dominant genes being formed. Hence, by using punnett square method, when Aa crosses with Aa, one of the results will be aa, which is the recessive genes.

Yes, if it is sex-linked. For example, a recessive allele that causes baldness but that is found on the x chromosome will cause baldness in men, since men only have one x chromosome. Since it is recessive, it will only cause baldness in women if they have 2 copies of the same recessive allele.

A "dominant" allele may be one of many different dominant alleles of the same gene. If it is not as dominant as another allele, then it will act as though it is recessive in a heterozygote with 2 different dominant alleles.
