The purpose for which a pedigree chart might be prepared is to identify the pattern of inheritance of a particular trait.
This pedigree chart is created so as to see which traits this new offspring has inherited from its ancestors and which may possibly be transferred onto a new offspring later on in its life. It is formed in order to find patterns of inheritance and see what the most important traits that get inherited are.
Answer:
A. Some pea plants grow slowly and have few offspring
Explanation:
This contrast the reason why Mendel chose pea plants.
They grow rapidly and produce a lot of offspring.
Answer: supersaturated
Explanation: A supersaturated solution is a solution in which the dissolved solute is more than the solvent can hold at that particular temperature.
A solution is a substance which sontains a dissolved solute. A solution can be saturated, unsaturated or supersaturated.
A saturated solution contains the maximum amount of dissolved solute a solvent can hold at that temperature.
An unsaturated solution contains less amount of solute than the solvent can hold at that temperature, this means that more solute can still dissolve in the solution.
A supersaturated solution contains more solute that can be dissolved in the solvent at that temperature.
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
