Answer #1

When two similar mutants are crossed and their F1 resembles either of the parents, it shows that both the mutants are allelic to each other i.e. they are located at the same locus.
When two similar mutants are crossed and their F1 does not resemble either of the parents, it shows that both the mutants are not allelic to each other i.e. they are located on different loci.
(This principle is applicable only to recessive mutations)

+ = WT phenotype = Non-allelic
-/0 = Mutant phenotype = Allelic

Complementation groups:
1. m = o = p = q = r
2. n = s

    A group of physics students collected data from a test of the projectile motion problem that was analyzed in a previous lab exercise (L5). In their test, the students varied the angle and initial velocity Vo at which the projectile was launched, and then measured the resulting time of flight (tright). Note that tright was the dependent variable, while and Vo were independent variables. The results are listed below. (degrees) Time of Flight (s) Initial Velocity V. (m/s) 15 20...

    Explain the following in terms a highschooler would understand (from article Expression of HoxD Genes in Developing and Regenerating Axolotl Limbs, 1998): DISCUSSION: Expression of HoxD genes in developing axolotl limb buds. We have examined the expression of Hoxd-8, Hoxd10, and Hoxd-11 genes in axolotl limb buds and find many similarities between the patterns of expression in axolotls and those described for other vertebrates. Similarities are most pronounced in phases I and II (Nelson et al., 1996; Shubin et al.,...

    2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
