6-2y.
1) -y - y + 7 - 1
2) -2y + 7 - 1
3) 6 - 2y
Step 1:
-y-y = -2y. If you want, you can reorder the terms first (this helps some people organize, separating the variables), making it 7 - 1 - y - y, but this is not necessary to solving the problem.
Explanation:
Variables can be added or subtracted like normal numbers as long as they have a common base (y, in this case) and the same exponent (The exponent is not written, so it is one. If you have not yet learned exponents, ignore this rule.) Variables are added or subtracted like regular numbers, so saying -y - y = -2y is like saying -1 - 1 = -2
Step 2:
Now we have the expression -2y + 7 - 1. Next, we add or subtract. (The order or operations is PEMDAS: after you've dealt with the variables, the order is Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.) So, 7 - 1 = 6.
This leaves us with our answer: -2y + 6, or 6 - 2y (they mean the same thing).
It is 0. Anything minus itself alone is 0.

-y is the additive inverse of y.
YY is phenotype Yy is not yy is a phenotype
yY
As of July 2014, the market cap for YY Inc. (YY) is $4,131,123,992.20.
The symbol for YY Inc. in NASDAQ is: YY.
In mice the YY genotype is lethal during embryonic development. This means that the mating of heterozygous individuals will produce a ratio of 2:1 Yy to yy offspring.A 'YY' genotype is homozygous dominant for that particular trait. If it is Yy, it will be heterozygous.
Crossing Yy x Yy yields YY, 2Yy, yy. Since Y is dominant over y, then YY and 2 Yy all result in the same phenotype. Therefore 3/4 of the offspring will resemble their parents.
Yy
Make two punnett squares- one for Yy x YY and one for rr x RR the possible outcomes for Yy x YY are: YY Yy the only outcome for rr x RR is Rr. so the gametes of the two could be either YY Rr or Yy Rr
here is an example: lets say you are crossing yy * Yy.. first separate the letters (they are called alleles by the way) so for yy --> you have y and y for Yy--> you have Y and y For the first gene yy --> put each corresponding letter on top as shown in the picture.. so horizontally. Now do the same thing for Yy but this time vertically. Then in the corresponding boxes combine the letters and there u have it
homozygous-2 genes that are the same ex. YY or yy heterozygous-2 genes that are different ex. Yy
