Answer:

Gametes from both dogs are needed to maintain the correct number of chromosome in the offspring

Explanation:

Reproduction in dogs is a <u>sexual process</u>. During the process, haploid gametes from both the male and the female (sperm from males and eggs from females) fuse together in a process known as fertilization in order to produce <u>diploid offspring.</u>

The haploid gametes ensure that the offspring produced during fertilization has the correct (diploid) number of offspring. Because the production of gametes involves <u>meiosis and crossing over of genetic materials between chromosomes, offspring produced by sexual reproduction are usually genetically different from one another. </u>The random fusion of gametes further ensures that offspring from the same parents are different from one another.

Explain how the melting of the sea ice may affect<br><br> people living on the coast of Florida.
Levart [38]

Since 2000, melting ice from the continent totaled enough to raise sea levels globally by about four tenths of an inch, according to the report which relied on the work of 90 scientists.  With what’s already baked into the atmosphere, faster melting land ice will likely add between 7.5 and 9.8 inches to earlier U.N. estimates by 2100, the report said.  And because of its position downstream, in an area of “preferential excitement,” South Florida could experience rise at the high end as water sloshes around the planet, Kirtman said.  “Think of it as pushing down the ocean [in Greenland]. The ocean is fluid, so it’s going to respond somewhere else and that somewhere else is down here,” he said.  In South Florida, planners already confronting flooding from sea rise have been more aggressive in assessing sea rise.

At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concl
Ray Of Light [21]

Answer:

The correct answer would be - Characteristics can be lost in evolution.

Explanation:

The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution

This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
