Answer: Maybe if you knew the def's you could answer it.

Initial Decay – Bacteria located mainly in the lower intestine begin decomposition, giving a greenish color to the lower abdomen. Stage 2: Putrefaction – Bacteria grow throughout the body, releasing gases, including cadaverine, which in turn bloat the body and cause unpleasant odor.

putrefaction

the process of decay or rotting in a body or other organic matter.

Black putrefaction occurs, which is when noxious odors are released from the body and the parts of the body undergo a black discoloration. 2 weeks: The abdomen is bloated; internal gas pressure nears maximum capacity. 3 weeks: Tissues have softened. Organs and cavities are bursting.

Fermentation occurring in putrefaction and apparently in the digestion of herbivorous mammals in which butyric acid is produced by certain chiefly anaerobic bacteria acting upon various organic substances (such as lactic acid or butter)

A dry body will not decompose efficiently. Moisture helps the growth of microorganisms that decompose the organic matter, but too much moisture could lead to anaerobic conditions slowing down the decomposition process

[Chapter 3-4] A cross was carried out between the following two pureline parental strains:Parent 1: A/A; b/b; D/D; e/e; F/FParen

andrew-mc [135]

Answer:

Following the selfing of the F1 from the cross between the two parental strains, what proportion of the F2 individuals will phenotypically resemble either one of the two parental lines?

= 7.03% of F2 progeny will resemble parent 1

= 2.34% of F2 progeny will resemble parent 2.

Explanation:

Parent 1: AA; b/b; D/D; e/e; F/F

Parent 2: a/a; B/B; d/d; E/E; f/f

F1 Progeny: A/a; B/b; D/d; E/e; F/f

knowing that the F1 progeny is selfed, the possible gamete outcomes are:

ABDeF , ABDEf, ABdeF, ABdEf

AbDeF , AbDEf , AbdeF , AbdEf

aBDeF , aBDEf , aBdeF , aBdEf

abDeF , abDEf , abdeF , abdEf

All gametes are either eF or Ef (the two parental genotypes) and never EF or ef.

At the A, B and D loci, the F1 are heterozygotes. Therefore, in the F2 progeny, for each locus, 3/4 of the progeny will have the dominant trait while 1/4 will have the recessive phenotype. Further, 1/2 of all F2 progeny will have the haplotype eF and the other half will be Ef.

<u>Proportion of progeny resembling Parent 1: </u>

Parent 1 has the Phenoytpe AbDeF. As previously discussed, 3/4th of all F2 progeny has the phenotype A, 1/4th of F2 progeny has the phenotype b, 3/4th of F2 progeny has the phenotype D and 1/2 of F progeny has the phenotype eF.

Thus, the proportion of progeny resembling Parent 1

= 3/4 x 1/4 x 3/4 x 1/2 = 0.0703125

= 7.03% of F2 progeny will resemble parent 1.

<u>Proportion of progeny resembling Parent 2</u>:

Parent 2 has the Phenoytpe aBdEf. As previously discussed, 1/4th of all F2 progeny has the phenotype a, 3/4th of F2 progeny has the phenotype B, 1/4th of F2 progeny has the phenotype d and 1/2 of F progeny has the phenotype Ef.

Thus, Proportion of progeny resembling parent 2

= 1/4 x 3/4 x 1/4 x 1/2 = 0.0234375

= 2.34% of F2 progeny will resemble parent 2.
