14. what are the genotypes of the brown and yellow labs who have all black puppies? show all your work using punnett squares.
Varvara68 [4.7K]

There are two different genotypes of brown labs and three different genotypes of yellow labs (eeBB, eeBb, and eebb) (Eebb and EEbb).

Let's examine genotypes, a different table now: As a result, a brown or yellow lab couple can have both brown labs and black or yellow labs.In actuality, neither brown nor chocolate dogs are permitted. Only yellow puppies can ever be born to a yellow lab couple. Even stranger, two brown labs can have yellow or brown puppies, whereas two black labs can have yellow or black puppies. Only yellow labs are capable of independently producing several shades of colour.

A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. When the rock is cut in half, what is the volume and d
spayn [35]

Answer:

Volume= 4 cm³

Density= 2 g/cm³

Explanation:

We have the following data:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³
