To ensure that the drinking
water for the public is safe, the Safe Drinking Water Act (SDWA) is
promulgated. The EPA is required to set standards for drinking water quality
and oversee all states in the area are implementing these standards.
Answer:
The F1 progeny is completely heterozygous for the <em>loci</em> of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids
Explanation:
An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single <em>locus</em>, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing).
The last answer box: Can be depended on
Answer:
Explanation:
Based on the scenario being described within the question it can be said that this can be confidently decided if you could show that the ranges of two mice overlap without hybridization occurring. This would allow you to safely predict whether or not two species of mice have mated with one another or if it two populations are one in the same.
