Use the punnett square to determine the ratio of offspring with: brown body and red eyes : brown body and brown eyes : black body and red eyes : black body and brown eyes :

because brown body color is dominant over black color

and red eye color is dominant over brown color.

hence brown body with red eyes will be in 3 , and brown body with brown eyes in 1 in first generation

it would lead to upper respiratory infections and pneumonia.
