During which stage of meiosis does crossing-over occur?

Biology
1 answer:
Delicious77 [7]3 years ago
7 0

Answer:

Prophase I

Explanation:

Meiosis is the cellular division that produces the gametes and results in 4 haploid cells. Since these cells will go on to become the offspring, it's important for genetic variation.

Crossing-over is one contribution of genetic variation because it is where the homologous chromosomes exchange parts of their genes. In meiosis, it occurs in Prophase I.

Hope this helps!

Which is a dominant genetic disorder?
ikadub [295]

Answer:

<em>The correct option is A) achondroplasia</em>

Explanation:

Achondroplasia is a genetic disorder which is caused in an autosomal dominant pattern. This means that an individual who even has a single allele for the gene will have the disorder. This is because a dominant allele masks the effect of the recessive allele.

Achondroplasia is a disorder in which the cartilage of the long bones of the arms and legs does not get converted into bones. It is a type of dwarfism.

Which two of your senses are linked together (i.e., influence your perception of both)?
Oduvanchick [21]

The correct answer is smell and taste.

The sense of taste and smell are related to one another because they have the same types of receptors. Odor comes from the molecules that is present in the air that stimulates the receptors that is present inside the nose. If one is not able to smell the or its sense of smell is non functional then it cannot have the sense of taste for the same food. This is caused due to the relationship between the smell and taste receptors.

nirvana33 [79]

Answer:

mutation affecting the biochemical pathway leading to the synthesis of leucine.

Explanation:

According to my research on studies conducted by various biologists, I can say that based on the information provided within the question this strain has a mutation affecting the biochemical pathway leading to the synthesis of leucine. Since a mutation is a permanent alteration in the DNA sequence, thus changing its affects.
