Does a recessive allele need another recessive allele to be expressed?
I think if an allele "want" to be expressed, then it has to have a dominant allele. They don't need another recessive allele.
A gene is recessive when?
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
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
What is a trait that is overridden by another trait?
Dominant- Covers up another form of a trait. Recessive- Is covered up by a dominant trait.
When on e allele of a gene masks the presence of the other allele what form is masked?
The 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 have?

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.
If one parent has two dominant alleles and another parent has two recessive alleles the offspring will be what?
yes I don't know
Trait of an organism that can be masked by the dominant by the dominant form of a trait?
A trait that masks another trait is called dominant, or a dominant trait.
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.
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.
Can full sized dogs have miniature offspring?
yes because if it is heterozygous dog that means that it has a dominant gene ( big ) and a recessive gene ( small ) and that means the dog is Tt capital t is dominant and if they breed with another homozygous recessive dog that means that out of every 4 puppies 2 will be big and 2 will be small ( p.s homozygous means that you have all dominant or recessive genes )
When can a recessive gene assert itself?
When a parent for example has one dominant and onee recessive e.g Fe and another parent is a carrier for it e.g ee this will make the gene produce a trait of the offspring having a 50% chance of being a carrier
Does a recessive allele need another recessive allele to be expressed?
I think if an allele "want" to be expressed, then it has to have a dominant allele. They don't need another recessive allele.

What is the name for a cross between an individual of unknown genotype and a homozygous recessive?
A cross between a homozygous recessive and an individual of unknown genotype is called a test cross.The homozygous recessive can only pass on a recessive allele to the offspring, and so any recessive in the other parent will show up in the phenotype (detectable characteristics) of some of the offspring.
