Answer:
Frequency of homozygous dominant genotype = 0.25
Frequency of heterozygous dominant genotype = 0.50
Frequency of homozygous recessive genotype = 0.25
Frequency of allele for left handedness = 0.5
And, frequency of allele for right handedness = 0.5
Explanation:
Allele frequencies:
Given that the frequency of recessive trait (left-handedness) is (q2) = 0.25
Frequency of recessive allele (q) = square root of 0.25 = 0.5
Since p+q= 1; so, p= 1-q = 1 - 0.5 = 0.5
Therefore, frequency of allele for left handedness (q) = 0.5
And, frequency of allele for right handedness (p) = 0.5
Genotype frequencies:
Frequency of homozygous dominant genotype (p2) = 0.5 x 0.5 = 0.25
Frequency of heterozygous dominant genotype (2pq) = 2 x 0.5 x 0.5 = 0.50
Answer:
Explanation:
Learning is a function of adaptation in which the nervous system changes in the relation to the environmental stimulus. This results in the change in the behavioral responses. There are three types of learning:
Classical conditioning can be defined as the process by which learner learn through specific events. For example, the dog hear the sound of bell which is indicative of lunch time.
Operant conditioning is a process by which a learner is either punished or rewarded to diminish or enhance a particular response.
Observational learning is a process by which a learner learn by observing others behavior.
DNA profiling. They compare his DNA profile to that of the Childs to see if they are related.
Oxygen, it takes in Carbon Dioxide and releases Oxygen as a waste :)
