Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.
Explanation:
Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)
Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. <u>It results in new combinations of genes on each chromosome.</u>
After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, <u>this means different chromosomes segregate independently of each other.</u>
Answer:
I would expect them to perform similar.
Explanation:
Studies suggest that intelligence has a genetic component and can, in part, be passed from parent to child - but not only that. There are outer components that contribute to the formation of intelligent individuals. Better nutrition and more access to education would be possible explanations for the progressive increase in intelligence test scores over time.
Homozygous twins are those that are mainly characterized by similarity between individuals. These twins are formed from the same zygote, ie after the fertilization process. Because of this characteristic, they have the same genetic heritage and are therefore considered identical.
As the homozygous twins in their classroom have the same genetic heritage and attend the same environment, we can conclude that their intelligence is influenced by the same factors. For this reason, a teacher who taught these two brothers might have expectations that they would perform similarly in the classroom.
Answer:
B. There is less biodiversity in the high tide zone because the tidal changes make survival difficult.
Explanation:
The high tide and low tide zones are located on the seashore as the ocean water merges with land.
High tide zones are usually covered with water during high ocean tide while low tide zones are always submerged in water.
There is low biodiversity in the high tide zone because the tide here changes rapidly and organisms find it difficult to adapt. Organisms that inhabit here must be welll adapted to withstand peroids of high tides.
