dusya [7]

Answer:

y = -5/2x - 4

Step-by-step explanation:

(0,-4) and (-4,6)

Slope:

m=(y2-y1)/(x2-x1)

m=(6+4)/(-4-0)

m=10/-4

m= -5/2

Slope-intercept:

y - y1 = m(x - x1)

y + 4 = -5/2(x - 0)

y + 4 = -5/2x

y = -5/2x - 4

MrRissso [65]

Answer:

For bbff we have only 6.3% probability

Step-by-step explanation:

If the parents are heterozygous for both traits, them they are represented by:

BbFf × BbFf

Parent 1: BbFf

Parent 2: BbFf

We have to find the percentage of occurence of bb × ff, which is a child that has blue eyes and no freckles, with no dominant factor.

By distributing the possibilities in a Punnett square, <em>vide</em> picture. We have the following possibilities:

Genotype Count Percent

bBfF 4 25

BBfF 2 12.5

bBFF 2 12.5

bBff 2 12.5

bbfF 2 12.5

BBFF 1 6.3

BBff 1 6.3

bbFF 1 6.3

bbff 1 6.3

For bbff we have only 6.3% probability
