Answer:
Frequency of B allele is 0.6681
Explanation:
If p represents the frequency of dominant allele and q represents the frequency of recessive allele, according to Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where p² = frequency of homozygous dominant genotype
q² = frequency of homozygous recessive genotype
2pq = frequency of heterozygous genotype
Given that number of recessive chestnut horse = 28
Total horses = 226 + 28 = 254
frequency of b² genotype = 28/254 = 0.1102
frequency of recessive b allele = √0.1102 = 0.3319
So, frequency of B allele =
1 - 0.3319 = 0.6681
Hence frequency of B allele is 0.6681
Dna extration from a onion and from a cauliflower would be different because even though all DNA is composed by the same nucleotides (A, T, C and G), the sequence of their genes will be different. That difference is why a cauliflower doesn't look like a onion. The cauliflower has genes that, when expressed, make the organism look like cauliflower and nothing else..

<h2>Succession </h2>
Explanation:
Succession is a phenomenon in which older communities are replaced by advanced and newer communities
- Primary succession is the one in which succession occurs at newer area where none of the community previously evolved
- Secondary succession is the one in which the substrate has already been prepared by the older communities so that the newer community which will arrive grow faster that is why secondary succession has faster pace
- Glacial retreats leave behind nothing but bare rock as they retreat from an area, leaving barren land from which primary succession can occur which enables scientist to study plant succession
Answer:
Ovaries
Explanation:
The function of the ovary is to produce the egg which develops in the Graafian follicle. The ovary is also responsible for the production of the hormones progesterone and estrogen.
