A plant can either have a smooth seed (p) or a rough seed (q). Rough seeds are recessive and smooth seeds are dominant. In a population of 100 plants, 32 of them have rough seeds.p^2 + 2pq + q^2 = 1
a) What is q^2?
b) What is q?
c) What is p?
d) If there are 19 plants with rough seeds in a population of 100, what is the allele frequency for smooth seeds?
Answers
p² + 2pq + q² = 1 and p + q = 1
where p and q are the frequencies of the alleles (p - dominant, q - recessive), and p², q² and 2pq are the frequencies of the genotypes.
a) Since 32 plants have rough seed (recessive genotype: q²) out of 100 plants in total, then
q² = 32/100 = 0.32
b) q = √q² = √0.32 = 0.56
c) Since p + q = 1, then
p = 1 - q = 1 - 0.56 = 0.44
d) 19 plants with rough seeds (recessive genotype: q²) in a population of 100 means that q² = 19/100 = 0.19
We need to calculate p (the allele frequency for smooth seeds).
We can find q because we know q²:
q = √q² = √0.19 = 0.44
Since p + q = 1, then
p = 1 - q = 1 - 0.4 = 0.56
I followed what the other user said and I think it's correct!
a) 0.32
b) 0.56
c) 0.44
d) 0.56

Answer:
Step-by-step explanation:
Given is a graph with more than 2 periods shown. The wave represents that it is the sine function.
From the graph we find that the graph gets its maximum at y=-2 and minimum at y =-6
Hence range =[-6,-2]
Amplitude = 2
There is no x intercept but y intercept =-4
Hence the possible equation would be
y = 2sin(bx+k)-4
for some real b and k
Since sine max value is 1, we have
Maximum value is 2-4 =-2

Anyways, we have to put one side of the ratio and match it to 48.

Or even better...

MAKE!!
A!!
PROPORTION!!
.
So... Let's say 7 is proportional to 48... so 7/5 = 48/x, where x is the number equivalent to ratio of 5.
.
Cross multiply!!
.
7x = 240.
.
Divide 7 on both sides.
.
x = 34 2/7.
