Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.
Explanation:
Answer:
frequency of dominant and recessive alleles - 0.6, 0.4
frequency of individuals with dominant, heterozygous and recessive genotypes - 0.36, 0.48, 0.16
Explanation:
Given -
Short ears (S) is dominant over floppy ears.
Total population of rabbits 
Population of rabbits with floppy ears 
Population of rabbits with short ears 
Frequency of rabbits with floppy ears is equal to

Thus as per Hardy weinberg's equation, frequency of recessive phenotype is represented by 
Thus,

Thus,

Frequency of rabbits with short ears only

Frequency of heterozygous rabbit (Ss)

Answer:
the light-colored form of the peppered moth has different genes from the dark form. The black color of the dark form was due to a mutation in the DNA of the light-colored form
