Sorry, in the present scenario the son will get your caste only.

Had your wife separated from you and the son was brought up solely by his mother only then he could have applied for caste certificate of his mother

if your son has been brought by his mother ie your wife as scheduled tribe then your child can be granted Sc certificate .

The SC held , "It also needs to be considered how far it would be proper to invoke the customary Hindu law to alter the caste status of a woman in an inter-caste marriage or a marriage between a tribal and a non-tribal and to assign the woman the caste of her husband when such a marriage may itself be in complete breach of the Hindu customary law."

It said there was a general presumption in inter-caste and tribal-non-tribal marriages to assign caste and tribe status of the father to the children, especially when the father belonged to upper caste or was a non-tribal.

"By no means is the presumption conclusive or irrefutable and it is open to the child from such marriage to lead evidence to show that he/she was brought up by the mother who belonged to the Scheduled Caste/Scheduled Tribe," it said.

In such cases, despite being born to a upper caste father, the child did not have an advantageous start in life and continued to suffer the deprivations, humilities and handicaps like any other community to which his mother belonged, it said.

I am quoting a SC judgment to your question. "In an inter-caste marriage or a marriage between a tribal and a non-tribal there may be a presumption that the child has the caste of the father. This presumption may be stronger in the case where in the inter-caste marriage or a marriage between a tribal and a non-tribal the husband belongs to a forward caste. But by no means the presumption is conclusive or irrebuttable and it is open to the child of such marriage to lead evidence to show that he/she was brought up by the mother who belonged to the scheduled caste/scheduled tribe. By virtue of being the son of a forward caste father he did not have any advantageous start in life but on the contrary suffered the deprivations, indignities, humilities and handicaps like any other member of the community to which his/her mother belonged. Additionally, that he was always treated a member of the community to which her mother belonged not only by that community but by people outside the community as well. In the case in hand the tribal certificate has been taken away from the appellant without adverting to any evidences and on the sole ground that he was the son of a Kshatriya father. The orders passed by the High Court and the Scrutiny Committee, therefore, cannot be sustained. The orders passed by the High Court and the Scrutiny Committee are, accordingly, set aside and the case is remitted to the Scrutiny Committee to take a fresh decision on the basis of the evidences that might be led by the two sides. "

The above mentioned decisions of the Hon'ble Supreme Court of India provide the answers to your question.

No. Son acquires the caste of his father only, not mother.

Son cannot acquire the caste of his mother.
