Crossing-over of chromatid segments during meiosis division I results in the formation of genetic variation.
<span>Crossing-over is an event during the meiosis (during prophase I)<span> and represents the exchange of genetic material between non-sister chromatids of homologous chromosomes. As a result of it, the creation of new combinations of genes on each chromosome occur. The exchange can happen many times within the same pair of homologous chromosomes, creating unique combinations of alleles.</span></span>

Crossing over of chromatid segments during meiosis division 1 results in new gene combinations.  Cross over occurs between prophase 1 and metaphase 1 and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. Additionally, it can happen during mitotic division ; which may result in loss of heterozygosity.

What is the major cause of phytoplankton blooms in the Gulf of Mexico?
3241004551 [841]

Answer:

Excessive nutrients from fertilizer run off.  

Explanation:

Scientists have suspected that phytoplankton blooms might be connected to agricultural run-off. They got some evidence from a recent study by comparing the timing of irrigation along the west coast of Mexico and phytoplankton blooms in Mexico’s Sea of Cortez. During the comparison, they had found a close correlation. Phytoplankton blooms occurred in the Sea of Cortez shortly after the irrigation. This happened because of carried fertilizers after irrigation and other agricultural run-offs into the sea.

The bloom detected in the Gulf of Mexico on December 13 might be similarly linked to agricultural run-off.

The x chromosome is found ________. the y chromosome is found ________. in both males and females; only in females only in males
elixir [45]

The answer is both in males and females; only in males. Males have one Y chromosome and one X chromosome, while females have two X chromosomes. In mammals, the Y chromosome controls a gene which is the SRY, which produces embryonic improvement as a male. The Y chromosomes of males and other mammals also contain other genes needed for normal sperm production.
