All long (Ll) but carrying the recessive for short.

Does a cactus have leaves?
No. Some may be considered as leaves but not really. Christmas cactus for instance grows in thin segmented stalks reminiscent of leaves. Cactus flowers have petal that are leafy and green like leaves but not really leaves. barrel cactus and saquaros obviously have no leafy protrusions beyond their flowers.
How does the range of phenotype differ between single-gene traits and polygenic traits?
Single gene traits are either one type or another,for example everyone is either (ABO System) group A,B AB or O with no intermediates - this shows discontinuous variation. In polgyenic traits, continuous variation is shown and there is a range with no discrete categories - height
How can an organism with a genotype Gg could have the same phenotype as an organism with the genotype GG?
Dominant alleles are expressed, even if a recessive allele is also present. In the notation used, a capital letter means a dominant allele - therefore the presence of a P (in either PP or Pp) means the organism will display the trait P creates.
How can two plants that have different genotype have the same phenotype?
No they do not. Say for example we are looking at the the colour of pea plants where R represents the allele for the colour red and, and the other allele r represents green. The plant will be red with the genotype RR AND Rr which are different genotypes.
Given Mendelian dominance and recessiveness how can parents with two phenotypes say eye color give rise to a few offspring with three phenotypes if a dominant needs a recessive to form a phenotype?
Eye colour is not controlled by a single gene, it is a combination of different genes that will ultimately dictate your eye colour. To understand this, we will first consider one of the genes involved. There are two alleles for this one gene, either 'blue' or 'not blue' eyes. A person who inherits a 'blue' allele from both parents will have blue eyes, ie we say that their phenotype (how they appear)is blue. A person who inherits a 'blue' allele from one parent and a 'not blue' allele from the other will have a phenotype (appearance)of 'not blue' eyes because 'not blue' is dominant over 'blue'. Then we must consider another gene that is involved. if you inherit 'not blue' eye colour then this other gene that you inherit will kick in and give your eyes some colour. A small amount of colour (melanin pigment) will make your eyes grey. More and more of this pigment can make them green, then hazel and then brown. eg - A blue eyed man (both his parents therefore must have had blue eyes) , married to a brown eyed woman (who had one parent 'blue' and the other 'not blue') could have children with blue, grey, green, hazel or brown eyes.
A cactus can either have long needles (L) or short needles or short needles (l) a cactus grower crosses two cacti .the cross is shown in the Punnett square apex?
D: Three long, one short
What type of cactus is the fishhook cactus?
The fishhook cactus may be either the fishhook barrel cactus (Ferocactus wislizenii) or Mammillaria dioica, also called the strawberry cactus or California fishhook cactus.
What is rainstick made from?
A dried up cactus with its needles driven into it, and either seeds, rice, pebbles or beans are filled inside, which is what makes the sound of falling rain. That is what the original rainstick is made from, but u can make it from nails and a tube of some sort with seals at the ends. :)
How do you get cactus needles out of skin?
soak the finger or body part with the thorn in vinegar. It can be either white vinegar or cider vinegar, they both work the same. Or place cotton saturated with vinegar where the thorn is , and leave it in there for 20-30minutes. The thorn will just fall out.
How does the roots of a cactus adapt to the desert?
Cactus roots have adapted by burrowing deep to reach water that is not quickly evaporated by surface heat. The stems grow very thick to act as a sort of insulation against evaporative loss. And the leaves have evolved as needles which have a low surface area to reduce evaporation and to deter animals and insects that would pierce the stem to suck moisture from the plant.
When one trait is not completly dominant over another?
This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.
What is it called when one trait is completely dominant over another?
This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.
What is an individual with genotype AAA described as?
An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
What are Turntable needles are called?
The plural form of a turntable needle can be either styli or styluses.
What is a phenotype-?
A phenotype is the physical trait or feature of an organism that is the effect of a particular genotype. Flower color of snapdragons is one example of a phenotype, and the color is determined by which alleles comprise the genotype. Plants that are homozygous for the flower color alleles are either white or red. Heterozygous snapdragons are pink.
What is the phobia of being frightened of hypodermic needles?
It's simple...needlephobia (I didn't expect that either)
Dominance that occurs whenever the hybrid genotype produces a new intermediate phenotype?
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.
