Chapter 10.4, Problem 1HYEW
Summary Introduction
To explain:
The reason behind the sterility of mules.
Introduction:
Reproduction is a way of maintaining the continuity of race. The reproduction can be asexual or sexual. The sexual reproduction involves two different parents. Each of the parents forms gametes, which at the time of fertilization fuses and leads to the formation of zygote which is genetically different from both the parents.

Rainbow trout go through a unique genetic reproductive process. Female eggs are diploid, while male sperm are haploid. In the wild, when the sperm fertilizes an egg, the extra set of chromosomes is kicked out, resulting in a diploid offspring.Triploid trout are produced in the lab to provide sterile fish stock for lakes. Shortly after the eggs are fertilized, scientists place them in a warm water bath to prevent the extra chromosomes from being removed. The result is a triploid fish that cannot reproduce.Rainbow Trout: n = 30Select the row that correctly shows the ploidy for the trout at different reproductive stages.

Global warming is an issue affecting many species around the world. Warming has caused the temperatures in lakes and rivers to increase and stay elevated for longer periods of time. Select the FOUR numbers that describe the possible effects of global warming on the reproduction of rainbow trout in the wild and on biodiversity.

The extra set of chromosomes is removed.
The offspring are diploid (2n).
The offspring are triploid…
A prairie grass species called "little bluestem" is tetraploid. It has four complete sets of chromosomes. There are ten kinds of chromosomes; in other words, each complete set of chromosomes has a total of 10 chromosomes. A single somatic cell (e.g., a cell in a leaf) will have 40 chromosomes, 4 of each kind of chromsome, i.e., 4 of the number 1 chromsome, 4 of the number 2 chromsome, etc. The illustration below shows prophase of meiosis 1 in chromosome number 10. In a diploid cell, there would be one tetrad (group of 4 chromatids) for each kind of chromosome. For example, there would be one tetrad for chromosome 8, one for chromsome 9, etc. When the tetraploid little bluestem undergoes meiosis, how many of chromosome number 10 will each sperm cell carry?

- Certain varieties of chrysanthemums contain 18, 36, 54, 72, and 90 chromosomes; all are multiples of a basic set of nine chromosomes. How would you describe these varieties genetically? What feature do the karyotypes of each variety share? A variety with 27 chromosomes has been discovered, but it is sterile. Why?arrow_forwardDuring meiosis, when crossing-over occurs between two homologous chromosomes, it does not happen at a single point, but rather two points with a stretch of DNA in between. What are the two junction points called?What is the region between the two points called and what is different about this region compared to how double-stranded DNA usually is?If the region described in b.) is located within a gene and the two homologues have different alleles of this gene, what might happen that is a direct violation of Mendel’s first law? (Describe the process with 2-3 sentences of detail.)arrow_forwardHomologous chromosomes only pair during meiosis. Why is this pairing important?arrow_forward
- In mammals, there are two sex chromosomes, X and Y, which behave like homologous chromosomes during meiosis. Normal males have one X chromosome and one Y chromosome, and normal females have two X chromosomes. Males with an extra Y chromosome (XYY) occasionally are found due to inappropriate segregation of the chromosomes (i.e. non-disjunction). Which of the following could give rise to such an XYY male? Answer Yes or No for each situation. nondisjunction in the first meiotic division of spermatogenesis; normal meiosis in the mother nondisjunction in the second meiotic division of spermatogenesis; normal meiosis in the mother nondisjunction in the first meiotic division of oogenesis; normal meiosis in the father nondisjunction in the second meiotic division of oogenesis; normal meiosis in the fatherarrow_forwardWith two pairs of homologous chromosomes, four kinds of gametes can be produced. How many kinds of gametes can be produced with three pairs of homologous chromosomes? What does this suggest for the 23 homologous pairs of chromosomes in human cells?arrow_forwardin metaphase 1 of meiosis, the homologous chromosomes line up side by side along the equator so that crossing over can occur between the homologous pairs and the homologous chromosomes can be pulled to opposite poles during anaphase 1. in mitosis, by contrast, homologous chromosomes line up single file along the equator. what benefits are derived from these two different ways that homologous chromosomes are positioned at metaphase in meiosis and mitosis?arrow_forward
- A cytogeneticist has collected tissue samples from members of a certain butterfly species. Some of the butterflies were located in Canada, and others were found in Mexico. Through karyotyping, the cytogeneticist discovered that chromosome 5 of the Canadian butterflies has a large inversion compared with chromosome 5 of the Mexican butterflies. The Canadian butterflies were inversion homozygotes, whereas the Mexican butterflies had two normal copies of chromosome 5. 1) Would a cross between Mexican and Canadian butterflies produce phenotypically normal offspring? and 2) Would the offspring of the cross (so F2 generation) be fertile?arrow_forwardPart C is actually 13 chromosomes in a cell of a pea plant that is monosomic for a single chromosome.

Why is this statement misleading? , Two famous male actors had twins using a surrogate mother who carried two embryos that hadbeen fertilized in vitro, one with one man’s sperm and the other with the other man’s sperm. In terms of genetics, how closely are the babies, a boy and a girl, related to each other if they have different fathers?arrow_forward
- . With regards to the grasshopper testes experiment, diakinesis is an ideal stage to determine chromosome number due to the degree of condensation of the chromosomes? Count the chromosomes at this stage. Does it represent a diploid or a haploid number?arrow_forwardYou are transported to a fantasy world where legendary creatures actually exist. In this world, a rhinoceros has 56 chromosomes and a horse has 54 chromosomes. When a female rhino mate with a male horse, a unicorn (!) is produced, but sadly it is usually sterile (cannot produce offspring). 5a. How many chromosomes does a unicorn have? 5b. Give one reason to explain why most unicorns are sterile.arrow_forwardIn a sample of 1000 patients with Down syndrome, a geneticist discovers that 95% of them are trisomic, while 5% have diploid number of chromosomes.
