figure abcd is reflected across the x-axis.

what are the coordinates of a' , b' , c' , and d' ?

enter your answer in each box.

a' ( , )
b' ( , )
c' ( , )
d' ( , )

A'(-1,-4)

B'(-5,-8)

C'(-5,-4)

D'(-4,-2)

Step-by-step explanation:

We have been given a graph of a quadrilateral and we are asked to find the coordinates of our quadrilateral after reflecting it across the x-axis.

We can see that coordinates of quadrilateral ABCD are:

A (-1,4),

B (-5,8),

C (-5,4),

D (-4,2).

Since we know that rule for reflecting an image across x-axis is . This means that y-coordinates of our given image will be negative.

So after reflecting our given quadrilateral across x-axis, coordinates will be:

Your answer is A. Individual #8 must be heterozygous for the trait.

Step-by-step explanation:

So the way a Pedigree Diagram works is vertical lines extending downward from a couple represent their offspring. The oldest individuals are found at the top of a pedigree, with each subsequent generation occupying the next level below.

When analyzing the pattern of inheritance of a particular trait, it is common to shade in the symbol of all individuals that possess that trait.

•If a parent is homozygous, having two of the same type of alleles for a given trait, all of the offspring inherit that allele.  

•If a parent is heterozygous, the offspring each have a 50/50 chance of inheriting either allele from that parent.  

Dominance determines if a given trait is exhibited by an organism.

•In complete dominance, the presence of a dominant allele (in either genotype: XX or Xx) means the phenotype of the organism is the dominant trait.  

•If only recessive alleles are present (xx), the phenotype of the organism is the recessive trait.
