In a population with two alleles, B and b, the allele frequency of B=0.59. What would be the frequency of the heterozygotes if t
Levart [38]

Answer:

0.483

Explanation:

The given population is in Hardy-Weinberg equilibrium. If the gene has two alleles, the sum total of the frequencies of these two alleles will be one.  

Therefore, the total of the frequency of allele B and frequency of allele b will be 1. f(B) + f(b)=1

If the frequency of allele "B" is 0.59, then the frequency of allele "b" will be=1-0.59= 0.41

The frequency of heterozygous genotype in the population= 2pq

p= frequency of the dominant allele

q= frequency of the recessive allele

So, 2pq= 2 x 0.59 x 0.41 = 0.483

garik1379 [7]

The question is incomplete as it does not have the options which are:

  • Adjusts the positions of the head, the neck, and the trunk
  • Perform respiratory movements
  • Stabilize or position parts of the appendicular skeleton
  • All of the above

Answer:

All of the above

Explanation:

The axial skeleton is the group of bones which forms the centre of the skeletal system. The central portion of the skeletal system includes bones of the skull, bones associated with the skull, the thorax, and the vertebral column (spinal cord).

There are 80 axial skeletal bones out of which 22 bones are present in the skull, 7 attached to the skull, 25 in a thoracic cage and 26 in the vertebral column.

The axial skeleton help maintains the position of the appendicular skeleton, maintain the posture of the body by maintaining the posture of the neck, head and trunk and also help in the respiratory movements.

Thus, all of the above is correct.
