7.1 Is There a Trade-Off between Current andDelayed Reproduction in the Collared Flycatcher?Suppose that you were studying a different population ofcollared flycatchers (Ficedula albicollis) and that you monitoredthe survival and reproduction of each bird throughout its entirelife. Some females reproduced for the first time when they were1 year old ("early breeders"), while others reproduced for thefirst time when they were 2 years old ("late breeders"). Theaverage number of eggs laid by early breeders and late breedersof a given age are reported in the table.Average number of eggs.Age (years)EarlybreedersLate breeders14.125.17.534.77.144.56.9Question 1. Graph the average number of eggs (on the y axis)versus age (on the x axis) for both early breeders and latebreeders. Please use MS Excel and copy your graph into yourMS Word assignment.Question 2. Do the results suggest that it would beadvantageous for birds to delay reproduction until they were 2years old? Explain.Question 3. Do the results indicate that allocating resources tocurrent reproduction can reduce an individual's potential forfuture reproduction? Explain.

Polyploidy is very common in flowering plants: approximately 40% of all flowering plant species are polyploids. Although polyploidy exists in many different animal groups, it is much less common. Why is polyploidy more common in plants than in animals? Give one or more possible reasons.
In c. elegans, genetics model organism, movement problems (unc) and small body size (sma) are encoded by two mutant alleles that are recessive to those that produce wild-type traits (unc+ and sma+). A worm homozygous for movement problems and small body is crossed with a worm homozygous for the wild-type traits. The F1 have normal movement and normal body size. The F1 are then crossed with worms that have movement problems and small body size in a testcross. The progeny of this testcross is: Normal movement, normal body size 210 Movement problems, normal body size 9 Normal movement, small body size 11 Movement problems, small body size 193 a)From the test cross results, can you tell if the two genes are on the same chromosome or not? Explain your reasoning. b)What phenotypic proportions would be expected if the genes for round eyes and white body were located on different chromosomes? (please explain hot to get to these conclusions)
The Forbes sea star and common sea star are broadcast spawners that are known to hybridize, yet they exist as separate, genetically distinct species (unique branches on the tree of life). One mechanism that may contribute to their uniqueness is prezygotic reproductive isolation, which is the incompatibility of gametes (sperm and eggs) from separate species. We know they hybridize, so the eggs and sperm are compatible, but could gametes from the different species be less compatible than the gametes from each individual species? Harper & Hart (2005) addressed this question in a series of cross-fertilization experiments. Did they find evidence that gametes ‘preferred’ to cross with gametes of the same species? Explain your answer.
Molecular geneticists have performed experiments in which they altered the number of copies of the bicoid gene in flies, affecting the amount of Bicoid protein produced. a. What would be the effect on development of an increased number of copies of the bicoid gene? b. What would be the effect of a decreased number of copies of bicoid? Justify your answers.
You are performing a series of experiments on fruit flies. You have a true breeding population of flies with red eyes, and a true breeding population of white eyes. You breed the population of flies to each other to get an F1 generation. In this F1 generation, 75% of the flies have Red eyes, 25% of the flies have white eyes. All the female flies have red eyes, half of the male flies have white eyes and the other half have red eyes. A statistically significant number of baby flies were produced in this cross. 1) What is that number? 2) What is the genotype ratio of the F1 generation? Give the genotypes.

On an island with no large predators, some ducks are born with a mutation that gives them stubby little wings. These ducks can’t fly, but there’s really no need to fly since there are no predators. In fact, they have an advantage because they don’t have to eat as much to support those big wings like the other ducks. Over time, the flightless ducks reproduce better than the regular ducks, and eventually all the regular ducks die out. What characteristic of life is being demonstrated here? Group of answer choices development high complexity evolution requirement for resources irritability
Scientists have also noticed unusual coloration among certain condor populations. Andean condors are typically black in color. However, a few unique white feathered individuals have occasionally been noted. These white feathered individuals are not well-camouflaged, and are easily spotted by larger predators. Recently, scientists noted that a black feathered condor had mated with a white-feathered condor, and their three chicks all appeared to have gray feathers. Closer examination of these condor chicks revealed that the chicks actually possessed a mixture of black feathers and white feathers, giving them a gray appearance from a distance. Please NAME and EXPLAIN the genetic phenomenon described here.
In marsupials, X inactivation occurs exclusively to paternally derived chromosomes. Which genes will ALWAYS be expressed in this situation? A. maternal X-linked genes B. paternal X-linked genes C. maternal Y-linked genes D. paternal Y-linked genes
Question 4 The sequenced genomes of many vertebrates have multiple Hox gene clusters. Why might these have been selectively advantageous in the evolution of vertebrates? In case of a Hox mutation, an embryo is more likely to be able to develop normally. A B) Having multiple Hox clusters ensures proper mouth-first gastrulation of the zygote. Having multiple Hox clusters allows vertebrates to evolve faster. D) In case of a Hox mutation, an embryo will be able to evolve new traits. 2 Points Question 5.
