A biologist doing a long-term study on a wild spider population observes increased variation in silk thickness. Which of the following could the spider population be experiencing? A) directional selection B) stabilizing selection C) disruptive selection D) genetic drift

The third mode of natural selection is disruptive selection (Figure 13.3). Here phenotypes close to the average have reduced fitness compared to phenotypes at the extremes. Disruptive selection appears to be the rarest form of natural selection and, indeed, there are few well-documented cases of it. There does not appear to be a good

Diploid organisms generate less variation in each generation, leading to less genetic variability on which selection can act. c . Haploid organisms have only one copy of each gene, which allows selection to act directly without recessive alleles being hidden in dominant phenotypes.

Males and females have equal variation in reproductive success… A biologist doing a long-term study on a wild spider population observes increased variation in silk thickness. Which of the following could the spider population be experiencing? Disruptive selection.

answer choices. Sharp reduction in population size due to an environmental disaster, often results in loss of variation. When individuals survive and reproduce at a higher rate than others in the same population. Process by which populations have become adapted to their environment over time.

Why does the fitness of a phenotype depend on frequency-dependent selection? A) Because selection favors the least common phenotype. B) Because the least number of alleles are at that locus. C) Because sexual selection produces dimorphism. D) Because frequency-dependent selection acts against extreme phenotypes.

For each group, we calculated the proportion of females that had a young infant (0–3 mo old) at any time during the study period. We included only infants <3 mo because they have a contrasting coat color and receive higher rates of natal attraction and infant handling than older infants with a black-and-white coat (Bădescu et al. 2014). We determined group stability as the number of years with stable female group membership, i.e., without female emigration, death, or immigration.

We applied a new method to develop uniform 10 μm thickness of high porous scaffolds using a computer-controlled knife coater with a motion stage and exploiting phase transition properties of a combination of salts and water in salt-leaching method. We then verified in vitro the effect of fast degradation by assessing the viability of primary mouse aortic smooth muscle cell cultured in the three-dimensional scaffolds.

A less invasive procedure (important in cases when GA is contraindicated or in bleeding disorders) 5. Less disruption of orbital tissues – chance of injury to EOM ,nerves and fat atrophy is reduced – Relationships between the muscles, globe, eyelids, and fornices remain undisturbed – Less chance of spread of infection to nervous system 15.
