In a large population of mice, 0.58 have the recessive genetic condition rsiancer (fictional). Assume the Hardy-Weinberg distribution. What fraction of mice are carriers? Giver your answer with two digits parts the decimal point.
WRITE ABOUT A THEME: INFORMATION The continuity oflife is based on heritable information in the form of DNA. In ashort essay (100–150 words), relate the structure and behaviorof chromosomes to inheritance in both asexually and sexuallyreproducing species.
Identify the most accurate statement about population variation. a. Allopolyploidy occurs when chromosomes fail to separate during gametogenesis and then self-fertilization results in a tetraploid offspring. b. Chromosomal duplications and deletions cause large changes due to the changes in gene dosage. c. Traits that are influenced by both environment and genetics are unlikely to be influenced by evolution. d. Gene duplications and deletions occur frequently during equal crossing over that occurs during meiosis I.
list and describe the ways meiosis increases variability; be able to discuss importance of genetic diversity. list and describe the processes of the central dogma of biology – the flow of information from DNA to protein.
In a population of 100 individuals, there are exactly 16 individuals expressing the recessive phenotype for a trait controlled by a single diallelic locus (i.e. a diploid organism). If the population is at genetic equilibrium, how many heterozygous individuals would you expect to find? 48 36 84 cannot be determined 16
Which statement best fits the principle of segregation? a. Units of heredity are transmitted to offspring. b. Two genes of a pair separate from each other during meiosis. c. Members of a population become segregated. d. A segregating pair of genes is sorted out into gametes independently of how gene pairs located on other chromosomes are sorted out.
Different populations of the tiny freshwater snails pictured in FIGURE 12.1 reproduce sexually, or asexually. Individuals of the sexual populations are diploid; those in asexual populations are diploid (3n, having three sets of chromosomes). Huge populations of asexual snails are disrupting ecosystems worldwide. Fertilizers and detergents contain a lot of phosphorus. So does DNA. Explain why you might expect to find more sexual snail populations in an unpolluted river, and more asexual ones in a river polluted by agricultural and urban runoff.
The idea that asexually reproducing populations might acquire and maintain (and not "breed out") harmful genes is summed up in which? Group of answer choices that meiosis reduces the chromosome number in half "adverse parental genome applicational theory" the lock & key hypothesis of random fertilization "Mutational Reducto Theory" Muller's Ratchet theory
Explain how meiosis and mutation can cause variation of traits within the population. In your explanation, be sure to include: crossing-over/synapsis, formation of haploid cells variations caused by mutations
