The cross of YyRr will produce 16 distinct genotypes.
If the two alleles are far enough on the same chromosome, then the Y and R alleles will be distributed independently of one another, so that the genotypic ratio among each allele would be 1:2:1 (YY:Yy:yy, and similarly for the R allele). Then the dihybrid cross will yield a genotypic ratio of 1:2:1:2:4:2:1:2:1 (YYRR:YYRr:YYrr:YyRR:YyRr:Yyrr:yyRR:yyRr:yyrr).
Now, assuming perfect Mendelian inheritance (complete dominance), the phenotypes exhibited by YY and Yy will be considered equivalent, and similarly for RR and Rr, so the phenotypic ratio would be 9:3:3:1 (YR:Yr:yR:yr).
Question 1: The correct answer is Option 3: 20
Question 2: The correct answer is Option 3: 27
Step-by-step explanation:
We put the term number as value of n in explicit formula to find the term.
<u>Question 1:</u>
Given
To find t4, we will put t=4 in explicit formula
The correct answer is Option 3: 20
<u>Question 2:</u>
Given, the explicit formula
We have to find the 5th term, putting n=5 in the explicit formula
The correct answer is Option 3: 27

Answer:
121.5
Step-by-step explanation: so what u are supost to do is multiply the sides which will give you your answer of 121.5.
Y = 8x + 12
if x = -6
y = 8(-6) + 12
y = -48 + 12
y = - 36
if y = 13
13 = 8x + 12
13-12 = 8x
8x = 1
x = ¹/₈ ≈ 0.125
Answer
-6x+7y=11
Step-by-step explanation:
I don’t know if this is the right way
The slope of the line is y=6/7x+b
If you plug in the 2nd point
2=3/7+b
B=11/7
Y=6/7x+11/7
7y=6x+11
-6x+7y=11
