a monohybrid cross between two heterozygous individuals results in 48 progeny with the dominant phenotype and 12 progeny with the recessive phenotype. You would like to determine if these results are significantly different from the expected ratios and you conduct a chi-square-test. What is the chi-square value?

    A mating between a heterozygous individual and a homozygous recessive individual results in 11 heterozygous progeny and 22 homozygous individuals. Do these observations fit a hypothesis of a 1:1 ratio of phenotypes? Conduct a Chi-square test to determine if these observations fit the hypothesis. Include: 1. The Chi-square value 2. The number of degrees of freedom 3. The p-value 4. Interpret what the p-value means. HTML Editor

  • In his analysis of F2 individuals in his one-factor ("monohybrid") crosses

    In his analysis of F2 individuals in his one-factor ("monohybrid") crosses, Mendel inferred the genotypes associated with dominant phenotypes by examining F3 produced by selfing the F2. You decide instead to test cross the dominant phenotype F, crossing them to recessive parents. Because you are busy with classes, you examine only eight progeny from each test cross to determine whether an individual F2 is pure breeding" or "hybrid like." What fraction of the dominant-phenotype F2 would you identify as "pure...

  • what is the difference between heterozygous and homozygous individuals

    What is the difference between heterozygous and homozygous individuals? Homozygotes have one chromosome while heterozygotes have two similar chromosomes. The homozygote will express the dominant trait and the heterozygote will express the recessive trait. All of the gametes from a homozygote carry the same version of the gene while those of a heterozygote will differ. Heterozygotes carry two copies of a gene while homozygotes only carry one. When constructing a Punnett square, the symbols on the outside of the boxes...
