Biology

The cloning process copies genes and chromosome pieces to generate identical material through nonsexual means. Cloning an organism creates a new organism with the same genetic information as a cell from the existing organism. What are two techniques used to clone an organism, thus making an exact copy of cells in the origina ...continues

Mendel/Punnett Square/Genotypes

Having a problem understanding Mendel's theory, would like help answering these scenario's. Have to write an report based on these questions please help Assume that “S” represents the dominant trait of having long leaves, and “s” represents the recessive short-leafed trait in a plant. In the parental generation, you cross ...continues

Is it the paternal or maternal X that is missing in the Turner's syndrome female?

2. An individual with Turner's syndrome and afflicted with the X-linked recessive trait nystagmus is produced by parents that are both phenotypically normal. The individual has a brother that is also afflicted with nystagmus and a brother that is phenotypically normal. Is it the paternal or maternal X that is missing in the Tur ...continues

Genetics Problems

1) Consider a genetic locus that could hold either of the alleles P or p (where P is dominant, p is recessive). Consider a second genetic locus (for some other unrelated trait) that could hold either of the alleles R or r. Listed below are some genotypes of individuals for each of these loci: a) PPRR b) PpRR ...continues

Chromosomes

How would a pair of sister chromosomes differ from homologous chromosomes? If the reproductive cell only has 23 chromosomes, then how come all of our body cells (somatic cells) have 46 chromosomes? Briefly describe the constituent molecules found within a chromosome. You may use a diagram to illustrate your answer. Refer ...continues

Genetics and questions about rosalind franklin, structure of the DNA, and DNA replication

What happened to Rosalind Franklin with respect to her career following the discovery of the chemical nature of DNA? Describe the structure of DNA in detail. Provide an additional image or images which clearly illustrate this structure. Reference your source. With your knowledge of the chemical nature of DNA, briefly sum ...continues

Hardy Weinberg Law

Of a certain population of 5,000 individuals, 450 of them have blue eyes. The rest have brown eyes. The gene for blue eyes is recessive. How many people in this population can be estimated to carry the gene (not expressed) for blue eyes?

MONOHYBRID CROSS for brown eyes and blue eyes in humans

In humans, brown eyes (B) are dominant over blue (b)*. A brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one of whom is blue-eyed. Draw the Punnett square that illustrates this marriage. What is the man’s genotype? What are the genotypes of the children? (* Ac ...continues

Genetic Material

All living organisms contain genetic information that provides several functions inherent to the individual organism and the perpetuation of its species. a) Describe how genetic material contributes to the regulation of physiological function and development b) Discuss how the nature of genetic material both perpetuates ...continues
