Answer 1

First of all if you want value of radio then make sure you have proper validation in place.
If you don't know how to validate then have a look at following link
https://laravel.com/docs/5.5/validation#validation-quickstart
Furthermore
If you want some default value for radio button then make sure you have a hidden field that will have default value is this case you dont need validation.
So the basic example would be
<input type="hidden" name="gender" value="bading" class="form-control">
The radio btn will always have bading as default weather its selected or not. But If you add
<input type="radio" name="gender" value="male" class="form-control">
<input type="radio" name="gender" value="female" class="form-control">
Then the hidden field is replaced with the selected value.

Answer 2

As #Sree mentioned, You need to give gender to the fillable.
protected $fillable = ['gender', ....];
As from the documentation :
Mass Assignment You may also use the create method to save a new model
in a single line. The inserted model instance will be returned to you
from the method. However, before doing so, you will need to specify
either a fillable or guarded attribute on the model, as all Eloquent
models protect against mass-assignment by default.

Answer 3

It might be because you forgot to add gender in your Mass Assignment. In your model add,
protected $fillable = ['gender', ....];
