The original population of 200 was hit by a flash flood and 100 organisms were wiped out, leaving 16 homozygous recessive out of

Scrat [10]

Answer:

frequency of homozygous recessive = q² = 0.16

the predicted frequency of heterozygotes = 2pq = 2 × 0.4 × 0.6 = 0.48

the predicted frequency of homozygous dominant = p² = 0.6² = 0.36

Explanation:

Given that:

Number of recessive homozygous survivors = 16

Total number of population survivors = 100

Predicted frequency of homozygous recessive individuals (q²) = 16/100 = 0.16

Frequency of recessive allele (q) = √0.16 = 0.4

p + q = 1

∴ p = 1 - q = 1 - 0.4 = 0.6

Frequency of dominant allele (p) = 0.6

frequency of homozygous recessive = q² = 0.16

the predicted frequency of heterozygotes = 2pq = 2 × 0.4 × 0.6 = 0.48

the predicted frequency of homozygous dominant = p² = 0.6² = 0.36

p² + q² + 2pq = 1

0.16 + 0.36 + 0.48 = 1 (proved)

The reduction in population due to some event in the original gene is no longer in the surviving population. Since the population is now small, there is likely to be genetic drift.

The flash flood caused change in allele frequency leading to a micro evolution.

If a segment of DNA were replicated without any errors, the replicated strand would have the following sequence of nucleotides:

Cerrena [4.2K]

5'-ACTCGTGA-3'-frameshift mutation (number of nucleotides in a DNA sequence is not divisible by three). deletion, one nucleotide in DNA is deleted, in this case A

5'-ATTACGTGA-3'- base substitution, C is substituted with T

5'-ACTACGTGT-3'- base substitution, A is substituted with T

5'-ACTAAGTGA-3'- base substitution, C is substituted with A

Substitution is a type of mutation in whichonly one base is changed. They can be:

• Nonsense mutations-when substitution leads to the formation of a stop codon instead of a codon

• Missense mutations-when one nucleotide is substituted and a different codon is formed

• Silent mutations-when a nucleotide is substituted and the same amino acid is produced

2018 liu comparative study of phrenic and partial ulnar nerve transfers for elbow flexion after upper brachial plexus avulsion a

aniked [119]

The broadly used nerve switch sources for elbow flexion in sufferers with pinnacle brachial plexus avulsion UBPA encompass partial ulnar nerve phrenic nerve and intercostal nerves.

A retrospective evaluation of twenty-one sufferers treated with phrenic and partial ulnar nerve transfers for elbow flexion after UBPA become executed.

In the phrenic nerve transfer institution, the phrenic nerve changed into transferred to the anterolateral package of the anterior department of the upper trunk; inside the partial ulnar nerve switch corporation, one fascicle of the ulnar nerve became transferred to the biceps department. The British scientific studies Council MRC grading machine, the attitude of elbow flexion, electromyography EMG, and the Disabilities of the Arm, Shoulder, and Hand dash questionnaire scoring were used to evaluate the recovery of elbow flexion at least three years postoperatively.

The performance of motor features in phrenic nerve switch establishments come to be eighty- percentage while it modified to 80 percentage in partial ulnar nerve transfer enterprise. The exceptional costs of the angle of elbow flexion were sixty-four percent and seventy percentage in phrenic and partial ulnar nerve transfer businesses, respectively.
