Brown mice disappear from the mouse population for two generations and then reappear in the third generation. Give two possible
gizmo_the_mogwai [7]

Answer:

The trait is inherited in the homozygous recessive pattern

Possible mating is between two heterozygous individuals

Explanation:

One possible explanation for this is that the trait for this brown mice has to inherited in the homozygous recessive condition. It is possible for this trait to skip two generations and then reappear if it has to be inherited in the homozygous recessive condition.

Another explanation to complement the first is that for this trait to reappear, there was mating between two heterozygous individuals (with one allele being domiant and the other being recessive). It is possible that all matings within the two skipped generations was between an heterozygous and a homozygous dominant or between two homozygous dominant individuals which will not produce the brown mice..

Match each moon or planet to the most accurate characteristic.
Olegator [25]

Each moon or planet matched to the most accurate characteristic;  

1. It contains large amounts of frozen water - C. Europa

2. High levels of carbon dioxide increase the temperature of its atmosphere - B. Venus

3. It does not have enough gravity to have an atmosphere - A. Earth's moon

4. Astronomers believe there is a good chance it contains liquid water - D. Mars

Europa is the smallest of the four Galilean moons of Jupiter. Others are Io, Ganymede, and Callisto. An outer layer of water, about 100 km (62 mi) thick, covered the surface of Europa. A part of the outer layer (crust) is said to be frozen, while the other part is a liquid ocean below the ice.

Venus is the second planet from the Sun and the hottest planet in the solar system. The atmosphere of Venus is dense, and it is composed mainly of carbon dioxide (roughly 96.5 percent), which traps heat and causes a greenhouse effect.
