Human Genetics

This would make both of his parents Dd genetypes.
Bob's sister could either not have the disease at all, DD, or be a carrier, Dd. If she was a carrier she then poses the chance of passing the disease on through child birth. Her father was unaffected, which means he must have been DD, which would make his mother probably Dd, so the chances are equal of Bob's sister being either DD, or Dd, with a fifty percent chance of being either of the genotypes.
Both DNA and RNA are made up of different tiny particles of information, often referred to as nucleotides. The nucleotides of Adenine, Guanine, Cytosine, and Thymine all make up DNA. In RNA however, Thymine is displaced and Uracil takes its place. It is these four proteins which help make up the coding and information of our bodies. Various proteins can then used these nucleotides, and based on the order they are in, read the information stored there. For example, the order of these nucleotides varies from species to species, and is always different for members of one species to members of another species.
The DNA is copied into RNA, which is almost identical to the original coding of the DNA. ...Show more

Summary

B. As demonstrated by the pedigree, no females have ever seen to be effected by the disease. The most likely cause of this would be the disease being sex linked, and linked to the X chromosome. If a female did happen to inherit the bad gene, she would end up with the genotype for the gene but would only be a carrier, and not actually develop the disease.

Genetics and Evolution
This phenomenon is clearly an evolutionary controversy. If phenotypic characters only are taken to be granted for discerning species, there really is no discerning phenotype between these species. This also means there are no clear-cut differentiating phenotypic features between the species of these geographic areas arranged in the form of a ring.

However, all plants produced in F1 generation would be heterozygous for their trait unlike their parents that were homozygous for their respective trait. If the F1 generation is further paired among itself by a yet another monohybrid cross than an F2 generation of plants will be produced.

Genetic material can also be passed between un-related individuals (e.g. via Transfection, or on viruses). Genes encode the information necessary to construct the chemicals (proteins etc.) needed for the organism to function. Parkinson's disease is one of a larger group of neurological conditions called motor system disorders.

This gives the phenotypic ration of 9:3:3:1, white disc, white sphere, yellow disc, yellow sphere. The genotypic ratio is 1:2:2:1:4:2:1:2:1. All combinations are represented and would therefore occur.

In order for such a procedure to be done, two RAD51 targeting constructs that contained either neomycin or blasticidin first had to be prepared. Once these targeting constructs were prepared, the RAD51 neo constructs were transpected into DT40 cells, and heterozygous clones were isolated for the RAD51 gene.
