Expert Solution & Answer

Explanation of Solution

Animals must exchange gases, nutrients, and waste products with the environment. This requirement imposes an additional limitation on body plans. A single-celled animal can perform its exchange activities easily as it is composed of sufficient membrane surface area compared to large animal. The rate of exchange is proportional to the membrane surface area involved in exchange, whereas the amount of material that must be exchanged is proportional to the body volume. The spherical-shaped large animal has the minimum surface area per unit volume, the ratio of surface area to body volume decreases, as body size increases. Hence larger animals with a spherical shape would face many challenges in carrying out exchange with the environment due to their body plan.

Conclusion

As evolution results in many changes in the elements like shape and size of animals, some evolutionary changes cause difficulties in their survival. The exchange of materials with the environment takes place across the membrane surface area of the animal. As there is no sufficient membrane surface area for spherical-shaped large animals, they face many complications in their exchange of material with the environment.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes.

Genes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be. What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle? What classes would be least frequent if locus f is in the middle? What classes would be least frequent if locus w is in the middle?
