To test the hypothesis that sperm animals are parasites, George Newport poured some sperm animals over some frog eggs. Based on the parasite hypothesis, the eggs should Shrivel and Die What was the dependent variable in Newport's experiment mentioned abov e ? extent of egg development G=Gamete A= 4 pairs Process occurs in the nuclei of reproductive cells within all organisms that reproduce sexually. Depicted process is meiosis What evidence did biologists use when working with Parascaris roundworms to test the hypothesis that the chromosome number is cut in half during gamete production? circumstantial When the leaves are removed from parent plants, the offspring plants have leaves. result The parents' observable characteristics are not directly transmitted to their offspring. conclusion Offspring body cells might resemble parent body cells due to hereditary instructions that are transmitted by chromosomes contained in egg and sperm cells. hypothesis/theory When the leaves are removed from parent plants, the offspring plants have leaves. result Cells are the structural and functional units of all living things. conclusion Genes are transmitted unchanged from one generation to the next. hypothesis or part of a theory 85 plants with purple flowers and 81 plants with white flowers were counted in the next generation. Or Assume fruit fly eye color is influenced by a pair of genes in which the gene for red eyes (R) is dominant over the gene for brown eyes (r). Also assume that the gene for normal wings (N) is dominant over the gene for shriveled wings (n). According to Mendel's theory, how many genes for eye color will end up in each sperm? 1 Suppose a male fly with an RrNn genotype produces sperm. What is the probability that any single sperm will have an RN genotype? 25% When calculating a chi square statistic for Mendel's cross of heterozygous pea plants (i.e., those presumably with the YyRr genotype), one obtains a chi square value of 0.51 and a probability estimate of about 0.92 (i.e., 92%). This high probability means that the observed results did not differ significantly from the predicted results. Therefore Most likely, Mendel's theory is correct. A plant that is heterozygous for tallness and red flowers is self-pollinated and has several offspring. Assuming that tallness and red flowers are dominant, what is the approximate probability of the following types of offspring? tall and white(19%) short and white(6%) tall and red(56%) Which of the following is not true of early embryonic development? Cells increase rapidly in size. According to the mosaic hypothesis, cell differentiation occurs because new cells come from different parts of the egg cell's cytoplasm.
