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.

Describes a trait or an allele that is expressed only when two of the alleles for the saame characteristic are inherited?
I believe the answer is dominant. Please don't be rude if this isn't the correct answer.
How are dominant and recessive alleles are represented in a punnet square?
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
What type of alleles mask recessive alleles?
Dominant alleles :-)
What is recessive and dominant mean?
I am pretty sure the recessive and dominant alleles you are talking about are covered in Biology. Recessive alleles are basically alleles that are received from both parent's DNA that are carries, (dd). However, dominant alleles are (exactly what it says) always expressed. If there is one dominant allele and one recessive allele the dominant allele overpowers the recessive. (DD) and (Dd)overpowers (dd).

What can be dominant or recessive?
Alleles can be dominant or recessive
How are dominant and recessive genes?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.

Are dominant alleles naturally better for an organism?
No, recessive alleles are equally likely to be inherited (if your dealing with only those two types of alleles). BUT, dominant alleles are the ones that show up. That is precisely why they are called dominant. Compared to recessive alleles, dominant ones will overrule the others, making it the one inherited.

How are Dominant and recessive alleles are represented in Punnet Square?

What is gene pair consists of two dominant alleles or two recessive alleles?
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
How dominant and recessive alleles are represented in a Punnett Square?
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
What type of alleles mask recessive alleles?
Dominant alleles :-)
A person with the alleles ii has what blood type?
Which statement describes the blood type of a person with the alleles IAi? It is type AB because I and i are codominant. It is type AB because A and i are codominant. It is type A because i is dominant and A is recessive. It is type A because A is dominant and i is recessive.
