∙ 11y agoIf the trait is sex linked the carriers are generally female. If the trait is not sex linked the alleles are carried by both males and females equally.

What is a trait that needs two factors in order to be expressed?
Actually, it is the recessive.................................................................UR WELCOME! :)
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
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.
What the different between a dominant and recessive trait?
In simple Mendelian genetics, there may be several alleles (variations) for a given trait. since organisms generally have two pairs of chromosomes, they have two alleles. A dominant allele is one that when it is present, always shows itself. A recessive allele only shows when there are two copies of the recessive allele. For example, suppose brown hair is dominant and black hair is recessive. If there are any copies of the brown hair allele, the person's hair will be brown. A person's hair will be black only if they have two copies of the black hair allele. In reality, genetics is much more complicated than simply dominant and recessive as many genes may influence one trait.
How do you describe homozygous and heterozygous individuals?
Homozygous is a term used to describe an organism that has two of the same alleles for a trait. If a person's alleles for eye color are BB (dominant dominant) or bb (recessive recessive), they are homozygous.
What types of alleles are expressed only if 2 identical copies exist on the homologs of the offspring?
Two copies of the recessive allele are the only way a recessive trait is expressed phenotypically.
What type of alleles are expressed only if two identical copies exist on the homolgs of the offspring?
Recessive because...

How long can a recessive gene stay hidden in a person?
A recessive gene will stay with a person for their entire life. Whether it will become obvious that the person is carrying a recessive gene is dependant upon how many copies of the recessive gene the person carries - the effects of a recessive gene will only become obvious if two copies of the gene are carried. Excluding the option of undergoing DNA testing for the recessive gene in question, it is perfectly feasible for a person to live the whole of their life whilst never knowing they carry a recessive gene for a certain condition.
What type of alleles are expressed only if two identical copies on the homologs of the offspring?
A recessive gene A recessive gene makes it harder for genes(or traits) to be passed on from parents to daughters.

Why are some parents traits expressed in their offspring and others are not?
Some traits are recessive and some are dominant. The recessive trait could be masked/hidden because of the dominant trait. Two copies of recessive alleles are needed to be shown in the phenotype.

What is the difference between heterozygous and homozygous alleles?
You're looking at a gene which contains 2 alleles (meaning variations of that gene). Let's call it "A."Remember that you get 2 copies of EACH gene (one from mom, one from dad).
