What is the result of a cross between an individual who is homozygous dominant and another who is homozygous recessive for a trait?
All the offspring will be heterozygous with a phenotype showing the dominant trait. Let the alleles be H (dominant) and h (recessive). All the gametes from the first individual will be H, and from the other, h. Thus all the offspring must be Hh.
What is two dominant alleles called?
In eyes, it would be brown is dominant, and blue is recessive. Free earlobe allele is said to be dominant over the attached earlobe allele. When an organism has two dominant alleles for a trait, it is called homozygous dominant. Two recessive alleles for a trait is homozygous recessive.
What are traits that are hidden called?
Recessive traits can be hidden if the organism inherits one dominant and one recessive allele (i.e. is heterozygous) for a gene. If a heterozygous organism mates with another heterozygous organism for the same trait, the recessive trait may be expressed in their offspring, which would mean that the offspring inherited two recessive alleles, one from each parent.
Is when one allele completely masks another?
when one allele is completely dominant over another allele, then it masks the expression of the second allele so the allele that masks the effect is called dominant allele and the allele whos effect is masked is called recessive allele
In which offspring does a dominant trait appear?
if a trait is recessive, it can only be expressed if its other trait is recessive as well. If the other trait in the genotype is dominant, it will block the recessive factor. But if both are recessive, they will be able to be seen in the offspring.
If one parent has two dominant alleles and another parent has two recessive alleles the offspring will be what?
yes I don't know

Another plant is said to be heterozygous for flower color what does this mean?
homozygous means that the alleles that make up the genotype are the same, for example homozygous dominant would have two dominant alleles (RR) or homozygous recessive would have two recessive alleles (rr). the alternative would be heterozygous, where the genotype contains both a dominant and a recessive allele (Rr). so a homozygous plant would either have two dominant alleles or two recessive alleles for the seed colour. Now the way to find out whether it is homozygous dominant or homozygous recessive is to do a cross with a homozygous recessive plant and look at the seed colour (the phenotype). if the the original genotype is homozygous dominant the offspring seed colour will show the dominant seed colour becasue it will be heterozygous. But if the original plant is homozygous recessive the offspring will show the recessive phenotype.

Are dominant traits more likely to be inheritd then recessive traits?
Yes. When looking at Gregor Mendel's laws of inheritance, the Dominant allele will always be inherited by the offspring, as it is more potent than the 'weaker' recessive allele (unless the recessive allele is present in both parents; this can be in the form of Aa or aa, but it must be present in both for the recessive allele to be present in the offspring). There are other cases, though, such as co-dominance, in which recessive alleles are more likely to be present in the offspring, but speaking in general terms, it is the Dominant (ex. AA / Aa) alleles that show up more commonly in offspring than the recessive (ex. aa) alleles.
How can a sister with the same parents have different hair colors?
Yes, this is possible. The parents may not have the same hair color as their offspring, because the offspring could have the hair color caused by a recessive allele. This allele could have been present in an ancestor, but not shown up again because its frequency is not as common as another hair color
In which offspring does a dominant trait appear?
if a trait is recessive, it can only be expressed if its other trait is recessive as well. If the other trait in the genotype is dominant, it will block the recessive factor. But if both are recessive, they will be able to be seen in the offspring.
How are two traits that have Dominant and Recessive alleles inherited?
The trait received is recessive.
When a trait has more than two alleles is that trait inherited?
If one parent has a dominant trait and and another parent has a recessive trait, then the recessive trait gets hidden while the dominant trait gets shown.
When an allele mask the presence of another allele it is said to be?
Dominent. Simple- you have two types of Alleles, Dominent and Reccessive. Imagine a punnet square for the allele that causes albinoism (A). One parent has Aa, or one dominent allele and one reccessive allele for the trait. If the dominent skin-tone gene wasn't there (A), then it would be AA and he would be an albino. But since he has a dominent allele, he has normal color. If he made a baby with another Aa combination, they would have 25% chance of having an AA baby with no reccessive allele, a 50% chance of having an identical Aa combination, and a 25% chance of having an albino baby, AA.
