Extra Credit Question: A wholphin is a rare hybrid animal born from mating a female bottlenose dolphin with a male false killer whale. Wholphins are diploid. Interestingly, wholphins are fertile. What can you conclude from the fact that wholphins are fertile? One of the parents must have been aneuploid Dolphins and false killer whales likely have the same number of chromosomes Wholphins are allotetraploid Dolphins and false killer whales are actually the same species

GENETICS In a sexually reproducing diploid organism in which 2n=6, a normal meiocyte in reduction should exhibit a total of 3 bivalents at the metaphase plate. Consider the following organism in the previous statement. if there is no crossing over, the number of possible haploids (gamete) genotypes generated by "chromosome shuffling" during meiosis is _____?
Corn has a chromosome number of 2=20. Supposing there are different aneuploidy/polyploidy in corn, provide the correct answer in the table below. 1. Type of aneuploidy/polyploidy Formula Chromosome Chromosome Types of gametes (n, n+1, n+2, n-1, n-2) number Configuration 1. monosomic 2. trisomic 3. double trisomic 4.nullisomic 5.tetrasomic 6. Autotetraploid 7. allotetraploid
Progeny of triploid tomato plants often contain parts of an extra chromosome, in addition to the normal complement of 24 chromosomes . Mutantswith a part of an extra chromosome are referred to as secondaries. James and Margaret Lesley observed that secondaries arise from triploid (3 n), trisomic (3 n + 1), and double trisomic (3 n + 1 + 1) parents, but never from diploids (2 n). Give one or more possible reasons that secondaries arise from parents that have unpaired chromosomes but not from parents that are normal diploids.
Chromosomes and Genetics Name 1. Edward and Jenna had 4 children together. They have a few "interesting" traits, shall we say! Look at the chromosome combinations that each child received and list their genotype and phenotype. Key: D= long eyelashes B = brown eyes F= freckles G = vampire teeth T= tall W = werewolf fur d = short eyelashes b = red eyes f= no freckles g = no vampire teeth t = short w = no werewolf fur
You are an allele on a single uncondensed chromosome in a Yellowfever-carrying mosquito (Aedes aegypti) diploid cell (2n = 6). Demonstrate in as much detail as possible (1) how you will get to each genetically identical diploid cell of the multicellular offspring; (2) how you will get to the next generation of sexually reproduced progeny. Help, I no understand. Perhaps you will?
Picture name - Tradescantia spathacea meiotic cell. HPO (400x)Shown below are photomicrographs of Rhoeo tradescantia cells undergoing meiosis. Answer the following question for each of the photomicrographs: Identify the cytogenetic abnormality observed (ex. ring, chain, laggard, bridge). Identify the meiotic stage in which these aberrations are observed (as shown in the photomicrograph). Explain how these aberrations are formed and relate to the possible causal mutation(s). Will this result to sterile and/or fertile gametes? Explain.
At the end of Meiosis II in human cells (specifically in males, for example), how many gametes are made from one original parent cell, how many chromosomes are in each gamete, and what is each chromosome made of (that is, if you compared, say, chromosome #1 in a gamete with the two #1 chromosomes the person inherited from his parents)?
The organism you are working with has the following chromosomes. Place the chromosomes of this organism onto the cell below such that the diagram accurately shows a primary meiocyte from this organism in metaphase I of meiosis. Note 1: Only place chromosomes you need. You don't need them all. Note 2: You can place the "Blank Box' image if you don't think you need a chromosome at a particular position. Dashed line - the metaphase plate 1.
In an electrophoretic gel across which is applied a powerful electrical alternating pulsed field, the DNA of the haploid fungus Neurospora crassa (n = 7) moves slowly but eventually forms seven bands, which represent DNA fractions that are of different sizes and hence have moved at different speeds. These bands are presumed to be the seven chromosomes. How would you show which band corresponds to which chromosome?
Please answer appropriately and do not copy-paste from Chegg or anywhere else. Give explanations to your answer. Diagram the types of gametes you would expect from a ++/yw female, given no crossovers, one crossover, two crossovers, three crossovers, and fours crossovers between non-sister chromatids of homologous chromosomes?
Diploid Number of chromosomes, Sex Chromosomes, (+/- whole) Chromosome (+/- partial) e.g. 47, XY, +14 = male with trisomy of chromosome 14 e.g. 46, XX, 1q+ = female with a partial increase to the length of the long arm of chromosome 1 (partial increases or decreases to a single chromosome still have the same diploid number) What is the notation for the following case? A man having Klinefelter syndrome and one Barr body.
While most animals cannot tolerate polyploidy, somemollusks, such as oysters, can. Although wild oystersare diploid, farmed oysters are often made triploid.The advantage of triploidy is that the oysters are sterile, so they expend the energy that would otherwise beused to make unappetizing gametes in the productionof delicious muscle. These meaty triploid oysters aremore valuable commercially than diploids.a. To make triploid oysters, researchers used cytochalasin B, a chemical that can inhibit cell division ineither meiosis I or meiosis II during oogenesis.This drug does not interfere with chromosomereplication. Explain how triploid oysters could begenerated using cytochalasin B.b. Cytochalasin B is toxic to humans, so oyster farmerscannot use this drug. Can you think of an alternatemethod that might enable oyster farmers to producelarge numbers of triploid oysters?
