Answer:
Water is contaminated with animal waste
Explanation:
DNA replication follows the base pairing rule (A with T and G with C). This ensures identical replication of the genetic information; hence it's conservation. Each daughter DNA double helix contains one old strand of DNA and one newly-synthesized strand of DNA. This is known as the semi-conservative mechanism.
DNA replication also occurs during mitosis which produces haploid gametes. Each parent contributes half of the genetic information during fertilization of two gametes, thus regenerating the diploid number. Genes from both parents are transmitted to the offspring.
Tadpoles are baby's and Frogs are grown. Tadpoles have tails and are beginning to develop and Frogs are fully or mostly developed.
A: Traits may be determined by multiple genes is the answer ...
The correct answer is: B) The F1 variance is due only to environmental factors.
According to Mendelian genetics: he crossed two purebred parents with differing traits to be sure that there were no other factors contributing to the outcome of the cross. When two purebred parents are crossed, all of the offspring should be genetically the same (heterozygous).
In the example above, we can see that there is phenotypic variance among the offspring, so we can conclude that it must be due only to environmental factors.
