  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

Crickets who cannot make a sound are less likely to find a mate and reproduce. For this reason, there are few crickets that cannot make a sound. This is an example of — (CHOICES: natural selection, replication, learned behavior)
NATURAL SELECTION
The process of choosing organisms for the most desirable traits for mating is known as –
SELECTIVE BREEDING

Two of the same alleles (both dominant or both recessive) HH or hh
What does heterozygous mean?
Hh, different alleles, one dominant allele and one recessive allele

What is budding?
a type of asexual reproduction in which a new organism develops from an outgrowth or bud
