1. A founder effect is a process in which some individual of a population deviate from the original population and travel to a different location and populates that area and form a new population. In the bottleneck affect a large population is destroyed by natural calamity leaving a small population behind. In natural selection, a gene that can adapt to the changing environment is flourished and the remaining genes are extinct. As we can see that some birds deviate and lands on a new island to populate that area. So this is a founder effect.
The answer is B.

Nitrogen fixation is a key component of biogeochemical cycling. It also represents an important inter-species interaction, which is: A. Commensalism between bacteria and animals B. Competition between plants and fungi C. Predation of bacteria by plants D. Mutualism between plant and bacteria In 1983, a population of dark-eyed junco birds became established on the campus of the University of California, San Diego (UCSD), which is located many miles from the junco's normal habitat in the mixed-coniferous temperate forests in the...
i need a drawing of a concept map for this article. The format of the concept map should be the is shown below, pick one that is suitable for this article. The concept map should be related to this article with explanation For a start, male & female African elephants (Elephas maximus) differ in tusk development. Most males have tusks, while many females are tuskless, or have small tusks. (This suggests that the genetic contol of tusk development must be...
According to Robert Trivers, why are men generally larger and more physically aggressive than women? Because women are more reproductively “valuable” than men, hence competition for mates is fiercer among men Because men invest more heavily in reproduction than women Because men secrete more testosterone Trivers’ theory does not speculate on the origin of the sex difference in size and physical aggression Although some women are interested in casual sex (short-term mating), research has suggested that there are differences in...
Practice questions for BIO 340 (Exam 2) I need help with these questions Please. WILL GIVE GOOD RATING 1. Wild type blue-eyed mary has blue flowers. Two genes control the pathway that makes the blue pigment: The product of gene W turns a white precursor into magenta pigment. The product of gene M turns the magenta pigment into blue pigment. Each gene has a recessive loss-of-function allele: w and m, respectively. A double heterozygote (Ww Mm) is self-pollinated. What proportion...

need help with this .. From the pages 571-587 attached below. 1a) Suppose a population of guppies was infected with a parasite. In that population a mutation results in a parasite resistant genotype that spreads through the population through natural selection. A subsequent mutation in the parasite results in a genotype that is unaffected by the newly evolved resistant guppy genotype. What is the name of the hypothesis that explains this host parasite “arms race”.? 1b) What is this name...
