Question

IQ had a high testability in twin studies however, environmental effects were negligible. however, we cannot assume differences among human population are genetic. therefore, differences among human populations must be genetic. therefore, intelligence is highly dependent on genotype. therefore, environment has little affect on intelligence. Which of the following is true regarding determining the number of alleles in a population sample? It may be impossible to count the number of alleles if one allele is dominant. When counting X-linked alleles it is only important to count the different alleles in males. Codominant alleles can always be counted because they produce unique phenotypes. 1 2 3 1 and 2 Alt of these In a population that experiences migration (i.e the merging of two separate populations), why are observed allelic and genotypic frequencies different than what is predicted by the Hardy-Weinberg equilibrium? The observed genotype frequencies were not created by random mating within the entire merged population. The observed genotype frequencies were created by random mating within the entire merged population. The observed genotype frequencies were subject to inbreeding. The populations experienced unequal survival rates. None erf these Which type of selection creates a dynamic equilibrium in which different alleles are retained in a population despite their being harmful in homozygotes? Balancing selection Disruptive selection Stabilizing selection Directional selection None of these Inbreeding within a population decreases the probability of finding identical between individuvals. Single nucleotide polymorphtsms can be identified in the human genome via Southern biotting. Blood vessels are induced to grow among cancer cels through a process known as angiogenests. The number of genes influencing a trait can be estimated by phenotypic segregation. When a population is a single interbreeding unit, it is said to be heterozygous. Genetic drift is as effective at fixing the recessive allele in a population as it is a domainant allele if no other factors are acting on the population. When conforming paternity it would be best to use unknown samples of DNA to prevent bias.
