Which of the following is most likely to produce an African butterfly species in the wild whose members have one of two strikingly different color patterns? Select one:

Exercise II: Monilophyta Part A: Ferns The ferns differ from other seedless vascular plants in their possession of megaphylls, larger leaves with multiple veins. Examine the many living fern sporophytes. There is much diversity in megaphyll morphology. (See also text Figures 17-23, 24, 26, and 36, pages 413, 414, 416, and 424). Identify the frond, the rhizome, and the roots. Most fern fronds are compound, with the blade divided into separate leaflets. If young leaves are present, notice how they unfold. These young leaves are often called fiddleheads. Examine the leaves for the presence of sporangia. Notice if they are grouped together in sori (singular: sorus), distributed evenly over the lower surface of the leaf, or in other patterns. The sporangia of some species may be protected by specialized outgrowths of the leaf called indusia (singular: indusium) (See text Figure 17-32, page 420). 6. Is the indusium diploid or haploid?. Obtain a small square of a fern leaf with one associated…

A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers. But caterpillars that hatch in summer feed on oak leaves and look like oak twigs. How does the same population of moths produce such different-looking caterpillars on the same trees? To answer this question, the biologist caught many female moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light Temperature Day Length Springlike Springlike conditions listed below. Springlike Summerlike Summerlike Springlike Summerlike Summerlike In each of the four environments, one of the caterpillars was fed oak…

Salamanders have a male heterogametic system for sex determinations where females are ZZ and males are ZW. The allele for the color of the tail is sex linked and the red allele is found on the W chromosome and the blue allele is found on the Z chromosome. You mate a male and female and they have 3 female offspring. What is the phenotypic ratio for tail color for their offspring? Group of answer choices 2 Blue : 1 Red 0 Blue : 3 Red 1 Blue : 2 red 3 Blue : 0 Red
