Single allele traits are: inherited characteristics that are controlled by only one gene form

Husband- Heterozygous since there are albino children.\nWife- Homozygous Recessive because it's the only way the recessive can show up.\nPigmented Children- Heterzygous since the dominant trait showed up but the other parent was homozygous recessive.\nAlbino Children- Homozygous Recessive for the same reasons as the mother.

In biology, a trait or character is a feature of an organism. The term phenotype is sometimes used as a synonym for trait in common use, but strictly speaking, does not indicate the trait, but the state of that trait (e.g., the trait eye colour has the phenotypes blue, brown and hazel).\n\nTrait: In genetics, a trait refers to any genetically determined characteristic. In technical terms, a genetic trait is amenable to segregation analysis rather than quantitative analysis.\n\nA dominant lethal trait is a trait that is expressed if present in the genome and therefore precludes having descendants. All such cases must necessarily be sporadic and must represent new mutations, not inherited ones (because a potential parent with the trait would die before being able to pass it along).\n\nA mendelian trait is one that segregates in accordance with the laws of genetics set forth by Gregor Mendel. Sickle cell trait is a mendelian trait. It refers to the situation in which a person has one copy (and one copy only) of the gene for sickle cell but does not have sickle cell disease (which requires two copies of the sickle cell gene). If two people with sickle cell trait have children together, each of their children has a one in four chance (25%) of having sickle cell disease.\n\nA nonpenetrant trait is a genetic trait that is in the genome but does not manifest itself in the individual. By contrast, a penetrant trait is one that manifests itself. If, for example, if 100 people have a particular genetic trait but only 80 of them express it, the penetrance of that trait is 80%.\n\nhttp://www.medterms.com/script/main/art.asp?articlekey=11705\nhttp://en.wikipedia.org/wiki/Trait_(biological)

Dominant traits are expressed in an offspring whether the individual has alleles Rr or RR while recessive is only expressed in rr individuals\n\nEven though an individual might have one r and one R, they will still exhibit dominant traits because it is a dominant allele

A chromosome is a WHOLE DNA molecule, so an allele has one molecule (one chromosome)

Each gene has to alleles and is inherited independently from other genes. Therefore for example Jj are 2 alleles of one gene and they will be inherited independently from Kk or Ll.\neach egg of a women whose genotype is JjKkLl, may have one of the following genotype:\nJKL, JKl, JkL, Jkl, jKL, jKl, jkl, jkL

There are two types of traits - Qualitative and quantitative.\n\nQuantitative traits are the ones which can be counted - e.g. your blood pressure, or your height etc, the size of the lumen of your aorta.\n\nQualitative traits are the ones which cannot be counted per se- e.g. the color of ur eyes, shape of your face, how good you feel, how successful you are, etc. However you can try to get surrogate measures for counting qualitative traits. For e.g. you can quantify how good you feel by determining the serotonin levels in the relevant parts of your brain, or something like that.

are you talking about genes? the complex arrangement of genes in numerous chains make up the characteristics of primates and most of all duel-reproductive organisms. out of the thousands, only a few have been mapped or pulled apart into single strands. the UCLA medical school has links to genetic mapping web sites. very cool!

Well if they ensure that the mate a homozygous dominant with a homozygous recessive (eg B/B x b/b, as is the case in monohybrid crosses, you can make sure the parents have this genetics by watching them over generations, mating only dominant with dominant and recessive with recessive) then you'd know that for a diploid plant/animal, as all offspring get one gene from one parent and one from the other, all of the F1 would have to be B/b - so heterozygous for that trait. So they'd all be the same genetically for that particular trait! But then if you crossed the F1 with one-another they wouldn't all be the same... crossing heterozygotes youd get some B/B, some B/b and some b/b...

Those terms are for individual genes, not people. A gene is made up of a pair of alleles, one from each gamete. These alleles can be one of many variations. If the alleles are identical, the gene is homozygous.

Traits that are genetically based can be inherited either dominantly or recessively.  Traits refer to what we call a phenotype, and the specific combination of DNA leading to this phenotype we call the genotype.  As an example, let's consider a pea plant which has two descrete and separate heights: large and small.  To analyze the inheritance of plant height, you first establish small or large plants that breed true, for example, crossing a large plant with a large plant always breeds large plants.  Then, you breed true-breeding large and small plants together.  If large is dominant (and small recessive), the offspring will all be large, because the 'large' genotype is dominanting the 'small' genotype.  If small is dominant the offspring are small.  Dominant and recessive are mutually exclusive classifications of the genotype.  \n\nTo extend this analysis further, you can cross that large x small generation (called the F1 generation) together (this is called an intercross).  Let's say large is dominant and the F1 plants are all large.  Intercrossing the F1 will lead to both small and large offspring.  If only one gene is responsible for the plant height, then the ratio of large:small plants will be 3:1.  \n\nThis is the essence of genetics, the linkage of genes to discrete, measurable characteristics.  Not all characteristics are genetic, and for complex issues such as diseases many genes play a role.  But the essence is still the same.  It works because for every person or plant, you receive one genome set from your mother and one genome set from your father, thus the inheritable characteristics you develop can then be passed down to the next generation.

There are two type of alleles: dominant and recessive.\n\nThe rule of dominance is basically that if dominant is present in the allele, the phenotype (appearance) will not show the recessive gene.\n\nIn Mendel's pea plant experiment, his dominant was purple flower  (PP) and recessive was white flower (pp). \nWhen he crossed purple with white, he got all purples, with genotype (gene) of Pp. Since purple is dominant and is present in genotype, the flower is purple.

> Allele is a gene concerned with one of the contrasting characters (Tall and Short).\n> The occurrence of more than two alleles in a population at the same loci in the chromosome is called multiple allele or repeat allele.
