Answer:
Number 3
Explanation:
Dominant: 20, Recessive: 20
An allele is the alternative of a gene. On his case, these beans represent the alleles for a simple Mendelian trait, where red is dominant (R) and white is recessive (r).
As states earlier there are 20 red beans (20 dominant alleles) and 20 white beans (20 recessive beans) and each beach represent an allele.
The arc length is calculated by using the equation below:
Arc length = 2πr ( C/360)
where r is the radius and C is the central angle.
<span>Arc length = 2π(6) ( 65/360)
</span>Arc length = 6.81 inches
Therefore, the correct answer is option C.
