What is independent assortment during meiosis 1? if two individuals mate, and each is capable of producing over 8 million potential gametes, the randorm chance of any one sperm and egg coming together is a product of these two probabilities - some 70 trillion different combinations of chromosomes in a potential offspring O a process where a single cell divides twice to produce four cells containing half the original amount of genefic information O homologous pairs of chromosomes line up in random orientations at the middle of the cell as they prepare to separate O swapping of genetic material

Meiosis Explains Mendels Results: Genes Are on Chromosomes The following diagram shows a hypothetical diploid cell. The recessive allele for albinism is represented by a, and d represents the recessive allele for deafness. The normal alleles for these conditions are represented by A and D, respectively. a. According to the principle of segregation, what is segregating in this cell? b. According to Mendels principle of independent assortment, what is independently assorting in this cell? c. How many chromatids are in this cell? d. Write the genotype of the individual from whom this cell was taken. e. What is the phenotype of this individual? f. What stage of cell division is represented by this cell (prophase, metaphase, anaphase, or telophase of meiosis I, meiosis II, or mitosis)? g. After meiosis is complete, how many chromatids and chromosomes will be present in one of the four progeny cells?
in the expermient of following chromosomal dna movement through meiosis, how many chromosomes were present when meiosis I started? How many nuclei are present at the end of meiosis ll? How many chromosomes are in each? What is the ploidy of the DNA at the end of meiosis l? What about at the end of meiosis ll? How are meiosis l and meiosis ll different? List two reason
Let’s suppose a pea plant is heterozygous for three genes, Tt Yy Rr, and each gene is on a different chromosome. How many different wayscould the three pairs of homologous chromosomes line up during metaphase of meiosis I?
in the experiment of following chromosomal dna mvement througgh meiosis, why. do you use non-sister chromatids to demobstrate crossing over? what combinatiobns of alleles could result from a crossover between BD and bd chromosomes? Identify two ways that meiosis contributes to genetic recombination. Why is it necessary to reduce the number of chromosomes in gametes, but not in other cell?
During zygotene stage of meiosis I, a remarkable pairing of chromosomes occurs. Look at the bottom part of As shown in which “mitosis: growth of the body” has produced cells with four different types of chromosomes. The black ones came from the sperm nucleus. The red ones came from the egg nucleus. If one of these nuclei were to undergo meiosis, which chromosomeswould pair during zygotene (which are homologous)— the long black one with the short black one or the long black one with the long red one?
If a diploid organism has 14 chromosomes (2n=14) a. How many chromosomes will its gametes have? b. After meiosis I during gamete formation, how many chromosomes are in each daughter cell? c. After meiosis I during gamete formation, how many chromatids are in each daughter cell?
If sisiter chromatids of one daughter cell from meiosis l failed to separate during meiosis ll, what would the resulting gametes look like? a. 2 gametes will have 2 of the effected chromosomes, and 2 gametes will have 0 of the effected chromosomes. b. non of the gametes will have any of the effected chromosome. c. 2 gametes will be normal, 1 garmete will have 2 of the effected chromosoms, and 1 gamete will have 0 of the effected chromosome. d. 2 gametes will be normal, and 2 gametes will have 2 of the effected chromosome. e. 2 gametes will be normal, and 2 gametes will have 0 of the effected chormosome
Why the concepts of haploid number, diploid number, andhomologous chromosomes are important for understandingthe process of meiosis ?
the Cavendish banana, the world's most popular fruit, is currently threatened by extinction due to a fungus. This banana variety is "triploid" and can only reproduce through cloning by cultivaors. Ginven what you know about meiosis, expalin how the banana's triploid number accounts for its inablility to form normal gametes. Considering genetic diversity, discuss how the absence of sexual reproduction might make this domesticated species.
If a hypothetical cell (2n=4) undergoes normal meiosis I, but during meiosis II, nondisjunction happens in one of the two daughter cells, how many of the four total gametes will have 2 chromosomes? 0 1 2 3 4
Assuming that such a fly would be viable, what would be the sexof a fruit fly with the following chromosomal composition?A. One X chromosome and two sets of autosomesB. Two X chromosomes, one Y chromosome, and two sets ofautosomesC. Two X chromosomes and four sets of autosomesD. Four X chromosomes, two Y chromosomes, and four sets ofautosomes
. In a certain strain of turkeys, unfertilized eggs sometimes develop parthenogenetically to produce diploidoffspring. (Females have ZW and males have ZZ sexchromosomes. Assume that WW cells are inviable.)What distribution of sexes would you expect to seeamong the parthenogenetic offspring according toeach of the following models for how parthenogenesisoccurs?a. The eggs develop from oogonial cells that neverundergo meiosis.b. The eggs go all the way through meiosis and thenduplicate their chromosomes to become diploid.c. The eggs go through meiosis I, and the chromatidsseparate to create diploidy.d. The egg goes all the way through meiosis and thenfuses at random with one of its three polar bodies(this scenario assumes the first polar body goesthrough meiosis II).
