Heterozygotes - Study guides, Class notes & Summaries

Imagine these genotype frequencies in a population: p2 = 0.49, 2pq = 0.42, q2 = 0.09. Now assume that there is nonrandom mating where individuals with one genotype will only mate with individuals that also have their genotype. Assume this pattern of mating goes on until the frequency of heterozygotes is effectively zero. In addition, there is also inbreeding depression such that individuals with the genotype represented by p2 die before they can reproduce. What will be the eventual frequenc...

McMaster Bio 1M03 Exam Questions with 100% Correct Answers | Latest Version 2024 | Verified Why might Pasteur's experiment be inconclusive? - The swan-necked flask broth may not support cell growth, or the broth was poisoned. Experiment did not confirm hypothesis that all cells come from pre-existing cells Why are replicates important in experiments? - To ensure that results were not achieved by random chance What is the definition of a replicate? - Unit that shares a common thi...

In cats, white fur results from a gene that codes for tyrosinase, an enzyme that catalyzes the product'n of pigment. A mutat'n in this gene creates an allele coding for enzyme that cannot funct'n. Consequently, the cat fails to produce pigment and remains white. correct answer: False The F1 generat'n consisted of heterozygotes for the gene that codes for color. T/F correct answer: true None of the black cats in the F1 generat'n could have the mutant allele, b/c they lack white fur. ...
