Autopolyploidy - Study guides, Class notes & Summaries

Adaptive Radiation - An evolutionary pattern in which many species evolve from a single ancestral species Allele - An alternative form of a gene. Allele Frequency - Number of times that an allele occurs in a gene pool in comparison to the total number of alleles allopatric speciation - The formation of new species in populations that are geographically isolated from one another. allopolyploidy - a species with multiple sets of chromosomes derived from different species Alpha (origination...

3 transfers of DNA - Transformation: bacteria takes up naked DNA Transduction: a virus transfers the genes Conjugation: a hollow tube, or pilus transfers genes between organisms A population has 700 individuals, 85 of genotype AA, 320 of genotype Aa, and 295 of genotype aa. What are the allele frequencies of A (p) and a (q)? A. p = 0.58, q = 0.42 B. p = 0.35, q = 0.65 C. p = 0.65, q = 0.35 D. p = 0.50, q = 0.50 - Total number of alleles = 700 x 2 = 1400 p = ((85x2)+320)/1400 = 0.35 q ...

fruit development ~ what happens when auxin is applied to the stigma of a unpollinated flower ? Provide food to animals eating the fruit even if pollination isn't successful à Maintaining dispersers alive for seeds that do develop ~ Advantage of having some parthenocarpic fruits for the plant? when there are more than 2 sets of chromosomes ~ what is polyploid Autopolyploidy ~ polyploid product of intraspecific crossing (2 parent cells from the same species) gibberellin ~ pl...

adaptative radiation - diversification of a group of organisms into forms filling different ecological niches allopatric speciation - aka geographical isolation: biological pops of the same species become isolated from each other to an extent that prevents or interferes with gene flow allopolyploidy - individual or strain whose chromosomes are composed of more than two genomes each of which has been derived more or less complete but possibly modified from one of two or more species -matin...

Interpret this statement: Extinct fossil species are typically succeeded by similar living species - Answer Extinct and living forms represent ancestors and descendants Which is an example of developmental homology a) gene content b) similar organismal structures c)vestigial traits d) similar embryonic traits - Answer d) Which is not one of Darwin's 4 Postulates: a) Individuals in a population vary in their traits b) These differences are not heritable; they are not passed onto offs...

Aberrant - Answer- Inappropriate recombination that results in the loss of genes from a chromosome Addition Rule - Answer- The probability of obtaining one or the other of 2 mutually exclusive events is the sum of their individual probabilities Alleles - Answer- Alternative forms of genes having the same position or locus on a pair of homologous chromosomes Amniocentesis - Answer- Fetal cells are analyzed for abnormalities of chromosome number and structure, generate a karyogram Amin...

CHAPTER CONCEPTS ■ ■ The failure of chromosomes to properly separate during meiosis results in variation in the chromosome content of gametes and subsequently in offspring arising from such gametes. ■ ■ Plants often tolerate an abnormal genetic content, but, as a result, they often manifest unique phenotypes. Such genetic variation has been an important factor in the evolution of plants. ■ ■ In animals, genetic information is in a delicate equilibrium whereby the gain or loss of a ch...
