Complete question:
Suppose a graduate student is studying a loss-of-function mutation in the mouse gene zigzag. Whereas wild type mice have straight tails, zigzag mutant mice have tails with two sharp kinks, so that the tail looks like the letter Z. To determine how the zigzag phenotype is inherited, he performs the crosses listed in the first column of the table below, using parents from true-breeding lines. Three possible sets of results from these crosses are shown. Determine the mode of inheritance of the zigzag gene that would yield each result set.
Mode of inheritance Options:
cytoplasmic-linked recessive inheritance, maternal effect inheritance, genomic imprinting (paternal allele is inactive), genomic imprinting (maternal allele is inactive), x-linked recessive inheritanceNote: You will find the table in the attached file
Answer:
Set A: X-linked recessive inheritanceSet B: maternal effect inheritanceSet C: genomic imprint (paternal allele is inactive)Explanation:
SET A:
X-linked recessive inheritance: This pattern refers to a recessive mutated allele that expresses the abnormal character and is linked to the X chromosome.
Cross 1: zig zag female x wild type maleParental) Xz Xz x X+Y
F1) Phenotype---> 50% zigzag (all males) ; 50% wild type (all females)
Genotype---> ½ X+ Xz ; ½ Xz Y
Cross 2:Parental) X+ Xz x Xz Y
F1) Phenotype---> From the whole progeny: 25% wild type females ; 25% wild type males ; 25% zigzag females ; 25% zigzag males - 50% wild type animals + 50% zigzag animals
Genotype---> ¼ Xx Xz ; ¼ Xx Y ; ¼ Xz Xz ; ¼ Xz Y
Cross 3: wild type female x zigzag maleParental) X+ X+ x XzY
F1) Phenotype---> 100% wild type animals (50% females + 50% males)
Genotype ---> ½ X+ Xz ; ½ X+ Y
Cross 4:Parentals) X+ Xz x X+Y
F1) Phenotype---> From the whole progeny: 50% wild type females ; 25% wild type males ; 25% zigzag males
Genotype ---> ¼ X+ X+ ; ¼ X+ Xz ; ¼ X+ Y ; ¼ Xz Y
SET B:
Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. The progeny genotype is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. This effect is commonly seen in insects, but it might also occur in mammals and plants. A much known experiment about this effect is the one performed on Limnea sp snail.
Cross 1: zig zag female x wild type maleParental) Xz Xz x X+Y
F1) Phenotype-->100% zigzag animals, due to the female´s phenotype, Xz Xz
Genotype--> ½ X+ Xz ; ½ Xz Y
Cross 2:Parental) Xx Xz x Xz Y
F1) Phenotype-->100% wild type animals, due to the female´s phenotype, Xx Xz
Genotype--> ¼ Xx Xz ; ¼ Xx Y ; ¼ Xz Xz ; ¼ Xz Y
Cross 3: wild type female x zigzag maleParental) X+ X+ x XzY
F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+X+
Genotype --> ½ X+ Xz ; ½ X+ Y
Cross 4:Parentals) X+ Xz x X+Y
F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+ Xz
Genotype---> 100% wild type animals
SET C:
Genomic imprint (Paternal allele inactive): Refers to a pattern that characterizes for epigenetically inheritance and for unequally functional paternal and maternal genomes. Males X chromosomes are inactive or imprinted and have a different function from those females X chromosomes. This is a common pattern in some mammals, insects and angiosperms. The paternal allele can not be expressed which causes an unequal contribution to the progeny phenotype.
Cross 1: zig zag female x wild type maleParental) Xz Xz x X+Y
F1) Phenotype--->100% zigzag animals, because the male´s X chromosome is imprinted or inactive
Genotype--->½ X+ Xz ; ½ Xz Y
Cross 2:Parental) Xx Xz x Xz Y
F1) Phenotype--->50% wild type animals ; 50% zigzag animals. Due to both the female´s chromosomes, Xx Xz
Genotype---> ¼ Xx Xz ; ¼ Xx Y ; ¼ Xz Xz ; ¼ Xz Y
Cross 3: wild type female x zigzag maleParental) X+ X+ x XzY
F1) Phenotype--->100% wild type animals, due to the female´s phenotype, X+X+
Genotype ---> ½ X+ Xz ; ½ X+ Y
Cross 4:Parentals) X+ Xz x X+Y
F1) Phenotype--->50% wild type animals ; 50% zigzag animals
Genotype ---> ¼ X+ X+ ; X+ Y (Wild type)
¼ X+ Xz ; ¼ Xz Y ( zigzag)

How does Islands formed?Oceanic islands are those islands which rise to the surface of land from the floors of the ocean basins. Continental islands are simply the unsubmerged parts of continental shelf which are entirely surrounded by water from all the sides. Many of the larger islands of the world are of the continental type only.
As volcanoes erupt, they build up different layers of lava which may eventually break the water surface. When the tops of these volcanoes appear above the water level, an island is formed. While the volcano is still beneath the ocean surface, it is known as a seamount. Oceanic islands can form from the different types of volcanoes.

In which layer of the ocean are you likely to find microscopic plants called phytoplankton?
Answer:
The Epipelagic Zone (sunlight zone)
Explanation:
The depth of this zone is about 200 meters (656 meters) below the ocean's surface. Phytoplanktons dwell there because sunlight penetrates this zone which facilitates the process of photosynthesis.

Water molecules are able to attach to
other substances, particularly if they are
also polar.
Answer:
Water molecules form hydrogen bonds with each other and are strongly polar. This polarity allows it to dissociate icons in salts and bonds to each other polar substances such as alcohols and acids thus dissolving them.

The siboglinid tube worm, found at deep-sea hydrothermal vents and cold seeps, has no digestive tract. It relies on symbiotic bacteria that live in the tube worm’s tissues. The bacteria oxidize hydrogen sulfide or methane for the worm.
What type of relationship is this?
Answer:
mutualism
Explanation:
There is a mutual benefit in both parties.
The relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism, a type of symbiotic relationship in which both organisms benefit from the interaction.
What is a mutualistic relationship?In a mutualistic relationship, both organisms benefit from their interaction with each other. This is different from parasitic or commensal relationships, where one organism benefits at the expense of the other, or where one organism benefits while the other is neither helped nor harmed. In the case of the siboglinid tube worm and the symbiotic bacteria that live in its tissues, the tube worm benefits from the bacteria's ability to oxidize hydrogen sulfide or methane, which provides the worm with a source of energy and nutrients. This is important because the tube worm has no digestive tract of its own and cannot obtain food directly from the environment.
Hence, the relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism.
