Mendel carried out his research on garden peas. You should remember that he used seven pairs of traits. Modern geneticists have

mapped the genes for Mendel's pairs of traits. Two of them are on chromosome 1, yet when Mendel carried out a dihybrid cross using these genes, his results led him to the conclusion that they assorted independently. This makes sense if:A. the two genes on chromosome 1 are more than 50 mu apart.B. the two genes on chromosome 1 are very close together.C. the two genes on chromosome 1 are at least 20 mu apart.D. the two genes on chromosome 1 never recombine.

Answer:

A. the two genes on chromosome 1 are more than 50 mu apart.

Explanation:

Two or more genes present on the same chromosomes are the linked genes. Linked genes do not assort independently and do not exhibit crossing over. Therefore, the linkage of genes results in deviations from Mendel's law of independent assortment. However, if the linked genes are present far from each other on the same chromosome, they may exhibit crossing over.

The greater the distance between the linked genes, the higher are the chances of crossing over. Crossing over of linked genes would result in some of the progeny to have the new gene combinations as it occurs during an independent assortment of two genes. Therefore, Mendel observed an independent assortment of two genes present together on chromosome 1 since they were present far apart from each other (more than 50 mu apart).

According to this article, why does the immature prefrontal cortex lead to<br> conflict for teens?
aivan3 [116]

Answer:

The immature prefrontal cortex lead to  conflict for teens because the teenagers when they try to use the frontal lobe for reasoning, they tend to overdo it and then giving their brain much work to do. This leads to conflict in teens.

Explanation:

In teens, the prefrontal cortex is immature and develops until the mid-20s of their age. It covers the front part of the frontal lobe. As a result of the immaturity of the prefrontal cortex in teens, they do not think or make decisions like that of adults. When they try to overdo with their immature prefrontal cortex, they end up in conflicts.

In connective tissue, the role of elastic fibers is to __________. provide tensile strength retain fluid provide flexibility for
Svetllana [295]

Answer:

provide flexibility

Explanation:

According to my research on studies conducted by various medical professionals, I can say that based on the information provided within the question the role of elastic fibers is to provide flexibility. Elastic fibers contain elastin, a protein that acts like rubber and allows them to stretch and recoil like rubber bands, making them very flexible.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
