Some people have freckles, and some people do not
have freckles. If a child has freckles, at least one parent
has freckles. However, the child may have a sibling that
does not have freckles. Which statement best describes
the presence of freckles? 1.Freckles are not determined
by DNA. 2. There are two alleles for freckles. 3.There is no
dominant allele for freckles. 4.Freckles are determined by
two genes instead of by one. If Mendel had crossed a true
breeding dominant plant with a true breeding recessive
plant, in which of the three generations is the recessive
trait visible? 1.F1 generation 2.P generation 3.F1 generation
and F2 generation 4.P generation and F2 generation.

I think freckles are not determined by DNA

Step-by-step explanation:

I have freckles and none of my parents do or ever have had freckles.

There are two alleles for freckles

Step-by-step explanation:

100 on edg

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
