If you want to put a value into an input via js, add an ID to the inputs and do the following:
JS:
document.getElementById('//inputId').value = '';
Jquery:
("#//inputId").val("");

How do I access the data inside the object?
You can check the request and response in f12 developer tool Network tab, like below.
and implement frontend code to populate input field(s) in ajax success callback function based on your actual returned data.
For example:
success: function (data) {
$("#fa-fatherhorse").val(data.fatherHorse);
//populate other inputs based on your actual returned data
How to replace Drop Down list ?
If you want to dynamically set the selected value/option of the dropdown, you can try:
$("#dropdown_id_here").val(value_of_selected_option);
If you want to dynamically append <option> to your dropdown, you can try:
var newoption = "<option value='" + option_val + "'>" + option_text + "</option>";
$("#dropdown_id_here").append(newoption);
