Answer:

The correct answer is - homologous chromosome exchange genetic information during prophase I.

Explanation:

Genetic variation or diversity in the offspring of an organism comes from the process of crossing over which takes place in gametes formation during meiosis.

In prophase I of meiosis I, the recombination or crossing over takes place in which the homologous chromosomes pair joins with a structure called synapsis, and segments or the arms of the non-sister chromatids are exchanged during the production of the gamets.

What modern process is thought to be similar to the way crust formed before plate tectonics began? The principles of convection
dlinn [17]

The formation of the Hawaiian Islands.

Explanation:

A modern process that is believed to be similar to the way crusts formed before the advent of plate tectonics about million of years ago is the formation of the Hawaiian Islands.

The Hawaiian Island is a series of volcanic Island which forms as result of volcanic activities on the oceanic plate.

  • Hawaiian Islands forms from a hotspot that supplies the ocean floor with sufficient magma as it rides.
  • This is similar to the volcanic activities that initially sculpted the surface of the earth.
  • During the early history of the earth, our very hot and restless planet poured out lava to the surface through which the crust formed.

Karen's blood type is b+. Jeremy's blood type is a+. Karen and jeremy have a child together, tommy. Tommy's blood type is o
Sophie [7]

It is possible for a child to have the blood type O if the parents have A+ and B+. However, this blood type has the lowest probability of occuring (6.25%),

The highest probability for an offspring with parents like Karent and Jeremy is AB with a chance of 56.25%. Next are A and B each with a chance of 18.75%.

However, if one of the parents is AB, then the chances for an offspring with O blood type is zero.
