each sperm cell could either have the dominant or the recessive allele for that trait

What describes the man's trait and the alleles in his sperm cells if he inherited the dominant allele from his mother and recessive allele from his father?
As long as you aren't talking about a trait or gene that behaves co-dominately or some other exception, the man would have the dominant trait show up and his alleles would be dominant and recessive (or Dd if you are using letter symbols for the alleles- upper case being the dominant allele from the mom's egg and lower case for the recessive allele from the dad's sperm). So for example if we are talking about the gene for earlobes we can use the letter E to represent the two alleles or genetic variations: E for un-attached earlobes and e for attached earlobes. A sex cell (sperm or egg) has one allele each so that when they unite to make an embryo the new person has 2 alleles- one from each parent. So if the man inherited a dominant allele E from his mom and a recessive allele e from his father then he would have Ee as his "genotype"(what alleles he has). His "phenotype" is what trait he shows, which would be what ever is dominant-- in this case E equals un-attached earlobes.
Is a sperm cell a haploid cell?
Sperm cells are haploid as they contain half the original starting material from the parent cell.
What does it mean if a plant is true breeding?
Mendel started out with plants that "bred true". That is, when tall plants were self-pollinated (or cross-pollinated with others like them), plants in following generations were all tall; when the short plants were self-pollinated (or cross- pollinated with others like them) the plants in following generations were all short.
What is the vehicle which transport the chromosomes from each parent to create a new human life?
the sperm and the egg
Is it true that egg and sperm each have twice the number of chromosome as parent organism?
No. Egg and Sperm gametes actually have half the number of chromosomes as the cells of the parent organism.
If the male parent cell is heterozygous for a traitTt what alleles could the sperm cells possibly have?
If a man has the genotype Tt, then he is heterozygous. Homozygous would be TT or tt. If a man has Tt, then he can either donate a T or a t to the sperm, but not both.
What alleles would be found in a horse's sperm?
A stallion's sperm carries a representative sample of all the stallion's alleles. Each sperm will have 50% (1N) of the stallion's 2N complement of alleles.
How many alleles does a parent pass on for each gene?
Only one allele of that gene. remember, meiosis halves the genetic material so that in sperm and egg there is a haploid count and only half the genetic material is passed on to the children; one half from each parent is is proper in sexually reproducing species. ( generally )
What is the sex cell from male parent?
sperm
How are genetics passed from parent to offspring?
sperm
What is the principle that each parent passes only one allele for a trait to its offspring?
-Each Parent Only Contributes One Allele Because It Only Need Half Of Each Allele To Make The Offspring. If The Same Person Gave All Of There Alleles It Would Be The Exact Same.
Gametes sperm and eggs contain the number of alleles found in other cell in the body of an organism?
one-half
Is a sperm cell is haploid?
Sperm cells are haploid as they contain half the original starting material from the parent cell.

Does sperm dies immediately?
Definitely not....sperm can live in a woman's body for 6 day's, possibly even 7!
