An organism shows the dominant phenotype, then one of its genes has to be the dominant allele,
but you cannot be sure of the identity of the other allele
unless you do a test cross to see if the dominant parent
breeds pure. let's pretend that you are in the dog-breeding
business. you know that long hair on a “pooch hound” is a
dominant allele and short hair is recessive. you purchase
a male long-haired "pooch hound." how do you figure out if your
male “pooch hound” is homozygous or heterozygous for long hair?
which genotype of female should you breed him to?
if a proper test cross is used, what phenotypes of puppies would you see
if your male dog is heterozygous dominant?
what puppy phenotypes would you see if your male dog is homozygous
dominant?
- complete the punnett square to
show the test cross that would convince someone that your "pooch hound"
is homozygous for long hair.
male genotype: -
female genotype:

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
