Answer:
Yes.
Probability of such child = 1/2 or 50%
Explanation:
According to the question, below are the genotypes and phenotypes possibilities:
aa = normal vision & no headache
Aa = normal vision & no headache
AA = blindness & headache
                                                                       Male                       Female
                                                                         Aa                            aa
Possible genotypes of progeny:            Aa        Aa           aa         aa
So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.
Mathematical expression is as under:
 2/4 = 1/2 that means 50% progeny. 
 
        
             
        
        
        
Answer:
- GgLl    x    Ggll ---> grey long x grey short 
 - Ggll    x    Ggll ---> grey short x grey short 
 - GgLL    x    ggLL   or   GgLL    x    ggLl ---> black long x grey long 
 - GGLl    x    GGLl    or  GGLl    x    GgLl ---> grey long x grey long  
 - GGLl     x     GGll    or   GgLL    x     GGll ---> grey short x grey long

Answer:
<h2>Gold</h2>
Explanation:
Assume Gold trait =P ,
Purple= p,
Given:
Gold (P) is dominant over purple(p), so P is dominant over p.
If the bear is homozygous pp ( recessive)  then bear will look purple,
If the bear is heterozygous Pp, then bear will look gold,
If the bear is homozygous DD( dominant), then the bear will look GOLD,
