Assume that you are a genetic counselor and that a couple seeks genetic counseling from you. Both the man and the woman are phenotypically normal, but the woman is heterozygous for a pericentric inversion on chromosome 8. The man is karyotypically normal. What is the probability that this couple will produce a child with a genetic syndrome as the result of crossing over within the pericentric inversion

Answers

Answer 1

Answer:

50%

Explanation:

An inversion is a genetic phenomenon that occurs when a chromosome breaks into two genomic sites, thereby the resulting DNA fragment is reversed and subsequently inserted into the same chromosome location. A pericentric inversion occurs when the chromosome breaks are located on opposite arms or sides of the chromosomal centromere. Moreover, crossing over (or recombination) is the exchange of genetic material between non-sister chromatids during gamete production. An inversion carrier, as in this case the woman who is heterozygous for a pericentric inversion, can produce four types of gametes. If there is no crossing over, half the chromatids will produce normal gametes (without the recombination event) and half the chromatids will produce balanced gametes that will transmit the pericentric inverted chromosome. On the other hand, if there is crossing over, half the chromatids will have one duplication on the first chromosome arm together with a deletion on the second chromosome arm, and the remaining half of the chromatids will have an inverse arrangement.

What is responsible for the red tide phenomenon? It is a phenomenon that usually coincides with storm surges; the name comes from the red kelp that often washes ashore as a result of rough weather. Red tide occurs in patches of water where certain species of dinoflagellates flourish. They are so abundant that the water becomes discolored and takes on a red hue. Red tides occur once a year and in accordance with the lunar cycle. The water appears red as a result of reduced levels of photosynthetic pigmen

Answers

Answer:

Red tide occurs in patches of water where certain species of dinoflagellates flourish.

Explanation:  

Red tides refer to the noticeable microalgae proliferation that can be recognized for being a big spot in the sea of a characteristic coloration. This phenomenon is caused by two microalgae groups: diatoms and dinoflagellates, both part of phytoplankton.

Red tides occur when certain environmental factors -such as temperature, light, nutrients availability, ph, etcetera- favor the overproduction of these organisms. These species produce toxins that turn to be dangerous for other animal species that feed on them.

Because these microorganisms produce pigments, their accumulation on the sea surface can be noticed as reddish, brown, or greenish color spots of variable extension.

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier. Group of answer choices

Answers

Complete question:

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.

Group of answer choices

A) behavioral . . . prezygotic

B) mechanical . . . postzygotic

C) temporal . . . prezygotic

D) gametic . . . postzygotic

Answer:

A) behavioral . . . prezygotic

Explanation:

The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.

There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.

Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.

There are different types of reproductive barriers.

Pre-copulatory o pre-ziygotic:

Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.  

Postzygotic mechanisms or barriers include

Hybrid inviability,   Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.

Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.
