Fur color in mice is determined by the same two genes that determine coat color in Labrador retrievers (gene B for coat color an

d gene E for deposition of pigment). If a brown female (her father was white) is crossed with a black male from a true breeding line, what colors and proportions would you expect in their offspring?

What is the process that occurs in the Vesicle? (Biology)
Mariulka [41]
Vesicles form naturally during the process of secretion(exocytosis), uptake (phagocytosis and endocytosis) and transport of materials within the cytoplasm. Alternatively, they may be prepared artificially, in which case they are called liposomes.

What is the process where organisms that are better suited to their environment reproduce and pass on their genes more successfu
maxonik [38]

Answer:

Natural selection

Explanation:

Natural populations have variations. Organisms of a population have various genetic traits. Some of these genetic variations make the organisms better suited to the prevailing environmental conditions. These organisms are more likely to produce more progeny. Over generations, the frequency of the beneficial genetic traits increases in the population due to the higher reproductive success of the organisms with these genetic traits.

This process of differential fitness of organisms of a population where the organisms with adaptive genetic traits have survival and reproductive benefits is called natural selection.

Population A consists of 100 hens that are fully isogenic and that are reared in a uniform environment. The average weight of th
qaws [65]

Answer:

a. the environmental variance (VE) = 3.5 g ²

b. 17.5 g ² for population

c. the heritability of broad sense (H2) = 0.83

Explanation:

a.With the information we have we can infer that environmental factors influence A, which is considered isogenic, thus, the environmental variance (VE) = 3.5 g ²

b.When studying population B, comparing it without environmental changes with respect to population A, we found that its total variance (VT) = 21.0g ²

We generate the following formula with the data obtained previously to find the genetic variation

VT = VE + VG

then VG = VT-VE

replacing data:

VG = 21.0 - 3.5 = 17.5 g ² for population

c. Regarding the heritability of broad sense (H2) in population B, we can reach the result with the data previously obtained like this:

H2 = VG / VT = 17.5 / 21.0 = 0.83

When wind slows down, it deposits sediment. What feature is created by the deposition of loosely packed, mineral-rich soil?
tamaranim1 [39]

The feature that is created by deposition of the loosely packed and mineral-rich soil is Loess.

Loess is a loosely packed soil deposition due to blown wind of sediment rocks. The geography of loess is in between soil and clay. It is finer in texture than soil but has the coarse structure than the clay. This loess contains certain clay portions in order to hold the soil particles properly.

It can be mostly seen in Great Plains of North America, northern china, and other places around the world.
