Consider the population of the jumping spider Marpissa muscosa from Homework 5 and 6. It is polymorphic for a 7 base-pair deletion. The presence and absence alleles are denoted by+ and-, respectively. Eggs of different genotypes have the following probabilities of surviving to adulthood Genotype Viability 55% 64%, 47%; How would you describe natural selection at this locus? O The allele is beneficial and dominant The+ allele is beneficial and recessive The alale s daids ddat O The +allele is deleterious and recessive O The + allele is neutral ° There is heterozygote advantage (overdominance) O There is heterozygote disadvantage (underdominance)
