Answer:
p = 0.36
q = 0.64
p² = 0.13
2pq = 0.46
q² = 0.41
Explanation:
We need to use the Hardy-Weinberg equations:
p + q = 1
p² + 2pq + q² = 1
p: the frequency of the dominant allele
q: the frequency of the recessive allele
p²: the frequency of homozygous dominant
2pq: the frequency of heterozygous
q²: the frequency of homozygous recessive
Here, we know that 328/800 people are homozygous recessive, which means that q² = 328/800 = 0.41.
Then, q = √0.41 = 0.64, and p = 1 - q = 1 - 0.64 = 0.36.
Now, we have p² = (0.36)² = 0.1296 ≈ 0.13 and 2pq = 2 * 0.36 * 0.64 = 0.4608 ≈ 0.46.
The answers are:
p = 0.36
q = 0.64
p² = 0.13
2pq = 0.46
q² = 0.41
Like plants, fungi often grow in soil. Unlike plants, Fungi cannot produce their own food. Instead they absorb nutrients from their surroundings.
Answer:
All the offspring have genotype RrTt
Phenotype is Pink and tall snapdragon
Explanation:
Given
Tallness ( T) is dominant to dwarfness (t)
Red (R) flower color is dominant to white (r)
It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance
Genotype of dwarf red snapdragon is RRtt
Genotype of a plant homozygous for tallness and white flowers is rrTT
The punnet square representing the cross between RRtt and rrTT is as given below-
Rt Rt Rt Rt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
Thus all the offspring have genotype RrTt
Phenotype is Pink and tall snapdragon
