1 answer:

3 0

<span>Polydactyly in its most common form, is an autosomal dominant mutation. Let's represent the mutation as P and the normal state as +. Thus, if both parents are heterozygous (P+), both would have the mutation (and thus have six fingered). They have 3/4 chances of having a child with the extra digit, 1/4 normal. </span>

2) How many solutions does the equation 4x + 2(x-5) = 3(2x - 4) have? Write down the final form as well as if it has no solution

Brilliant_brown [7]

Answer:

0 = -2, hence no solution.

Explanation:

4x + 2(x-5) = 3(2x-4)

4x + 2x - 10 = 6x - 12

6x - 6x = -12 + 10
