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:

the answer is "a.) well–developed vascular system."

explanation:

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
