For example, if we are talking about a population of beetles, and the females prefer to mate only with larger males if they can, then the alleles present in the smaller beetles will be less likely to pass on than the alleles in the larger beetles.

Genotype association. How is the gene pool of a Mendelian population usually described? a. the same allele on both homologous chromosomes b. two different alleles of a gene c. a haploid condition, in genetic terms, The combination of alleles that independently assort is usually higher than the number of chromosomes because A. gene linkage B. crossing over C. segregation D. translocation E. jumping genes, One gene influences multiple characteristics: A.
