An organism has the allele frequency of a a=0.4 and b=0.3. What's the frequency for allele=c?

The frequency of allele c = 0.3

Explanation:

An allele frequency is determined by dividing the number of occasions the allele of intrigue is seen in a population by the complete number of duplicates of the considerable number of alleles at that specific hereditary locus in the population. Allele frequencies can be represent to as a decimal, a rate, or a division.  

the frquency of the dominant (ordinary) allele in the population (p) is essentially for example 1 - 0.02 = 0.98 (or 98%).

so, the frequency of allele c will be

1 (p)= a + b+ c

1 = 0.4+0.3 +c

1- 0.7 = c

c = 0.3

the frequency of allele c = 0.3

b. heterotroph

explanation:

this is a good question! i'll do some research and come back when i have the answer!
