Question.241 - Steps of MEIOSIS Which cell below is considered to be haploid? a zygote , Not Selected a somatic cell , Not Selected a germ cell, Not Selected Correct answer: a sperm cell Independent alignment of chromosomes occurs during prophase , Not Selected does not increase genetic diversity , Not Selected is the exchange of DNA fragments during prophase , Not Selected Correct answer: increases genetic diversity Which event occurs when a Germ cell is in S phase of the cell cycle? A spindle forms. , Not Selected Chromatin condenses into chromosomes. , Not Selected Correct answer: The cell replicates all of its nuclear DNA. Sister chromatids separate and move to opposite poles of the cell. Non-Mendelian Genetics A black eyed cat mattes with an orange-eyed cat and all of their offspring from this pairing have black eyes. Assuming these genes follow Mendelian genetics, what is the expected phenotypic ratio of a cross between two orange-eyed cats? Correct answer: all the offspring will have orange eyes. all the offspring will have black eyes., , Not Selected 2 black eyed and 2 orange eyed kittens. , Not Selected 1 black eyed and 3 orange eyed kittens. An individual who is heterozygous for an autosomal recessive disorder will Correct answer: not be sick or disabled can not pass this gene on to 100% of their offspring. , Not Selected will be sick or disabled from this disease , Not Selected will pass this faulty gene on to 100% of their offspring. During meiosis, genes separate equally when forming gametes so that each offspring has an equal chance of inheriting any particular gene. This is called Law of Independence , Not Selected Sexual Reproduction , Not Selected Random fertilization , Not Selected Correct answer: Mendel's law of segregation Cell Division Wrap Up During meiosis, how many times does the cell go through interphase and replicate its DNA? It depends on whether the cell is a germ cell or a somatic cell. , Not Selected Correct answer: once twice , Not Selected zero Genetics When Mendel mated a dominant purple flowered pea plant with a recessive white flowered pea plant, what did he discover? All the offspring in the F1 generation had white flowers. , Not Selected All the offspring in the F2 generation were hybrid. , Not Selected Correct answer: All the offspring in the F1 generation had purple flowers. Purple and white flowered pea plants do not produce offspring. Mendel mated purple flower plants with white flower plants and produced a number of generations. In the F2 generation of this experiment, Mendel found 100% of the F2 generation had white flowers. , Not Selected 100% of the F2 generation had purple flowers. , Not Selected Correct answer: None of these statements are correct. 50% of the F2 generation had purple flowers and 50% had white flowers. Variations of genes that exist at the same locus (location on the chromosome) are called mutations , Not Selected dominant , Not Selected Correct answer: alleles loci
