It is C as to have freckles you have to have a dominant and recessive gene (can be worked out using a punnett square) as the child has 50% of not having freckles like his dad or 50% having freckles like his mom. 
                     male genes(homozygous recessive)
                     f            f
female    F    Ff           Ff
genes
              f     ff             ff
so ff is not having freckles and being homozygous recessive, or Ff having freckles and being heterozygous.
So the child is heterozygous  so C
        
             
        
        
        
Answer:
1/4 suffer from hemophilia 
1/4 are heterozygous 
Explanation:
So since they are normal but their son isn't it is assumed that the mom is the carrier since the dad has to be X^HY
 X^HY x  X^HX^h
Set up a pedigree 
X^HX^H X^HX^h
X^HY     X^hY
1/4 suffer from hemophilia (X^h)
1/4 are heterozygous (X^HX^h) 
 
        
             
        
        
        
Answer:
Phenotypes
Explanation:
Heritability refers to the extent to which trait variations among individuals are attributable to their differing observable and most often definitive or measurable physical features, often called phenotypes. Examples of this variation could be something like height or eye colour. Basically it has to be traits that depend on genetics that environmental factors
 
        
             
        
        
        
Antlers are generally only found on male deer in other species of deer. Females with higher-than-normal testosterone levels, on the other hand, can grow antlers.
<h3>
Why Do Deer Grow Antlers?</h3>
Antlers are grown by male deer to lure female deer for mating. Females will be shown a display as the antlers are developing during mating season, with each male attempting to become the most dominating.
Deer utilize their antlers to protect themselves from predators and other deer. When deer attack each other, their antlers might lock together, forcing the deer to starve to death.
