TYPES OF BREEDING Selective Breeding Terms * When you breed plants‚ the results are known as cultigens‚ cultivars or varieties. When there is a cross of animals‚ the results are referred to as crossbreeds‚ while a cross of plants results in hybrids. Similar methods are used in animal and plant breeding. When animals with desirable traits are selected‚ they are bred through the process of culling for particular for traits. Culling is the process of selecting livestock based on desired criteria

Genetics & Drosophila Melanogaster Lab Report Background: For two months‚ you will breed Drosphila melanogaster (fruit flies) and set up genetic crosses in order to determine the pattern of inheritance of certain mutant traits. The traits for which we will examine the pattern of inheritance are apterous (wingless)‚ vestigial (crippled wings) or white eyes. These are all mutant strains. The normal condition (winged and red eyes) is referred to as the wild type strain. Objective: The intial

Using P-element Induced Male Recombination to Generate a Deletion in the DMAP1 Gene on Chromosome Two in Drosophila melanogaster Abstract: The goal of this study was to induce a deletion in the DMAP1 gene on chromosome two in Drosophila melanogaster through P-element mobilization. The DMAP1 gene may be an essential gene‚ however not much is known about it. We attempted to uncover the function of DMAP1 by creating a series of genetic crosses and selecting for brown-eyed non-stubble male flies

letter can be together with a dominant gene or another recessive gene. For example: suppose that in bees‚ the shape of their body is dominant when shaped as a cone (S)‚ and recessive when shaped as a sphere (s). In this case the genotype would be S or s and the phenotype would be the shape of the bee. If a bee has SS or Ss‚ it will be shaped as a cone‚ but if it is double recessive ss‚ it will be shaped as a sphere. Even though the probability of having double recessive genes is lower‚ some traits

electrophoresis was conducted to see if any DNA fragments were present. A band was visible and that validates that genomic DNA has been isolated. PCR Amplification to Determine Strain of P. larvae with ERIC-Specific Primers ERIC-specific primers were used to genotype the genomic DNA of P. larvae isolated from the spore solution. A faint band present at 970 bp was present within all six lanes. Also‚ a prominent band was migrating around 1200 bp within all six lanes. Additionally‚ a double band between 1500 bp

The Theory of Evolution One of the greatest questions of all time is: "Where did we all come from?" One of the most popular answers to this question is creationism‚ the idea that everything was created by a higher being. Another popular idea is evolution‚ the idea that all living organisms descended from a less complex organism. Evolution possesses a new way of thinking that is being greatly accepted by the scientific community‚ but not by pious groups of people. Creation and evolution are diametrically

PWS occurs when there is a defect or deletion in the fifteenth chromosome from either maternal or paternal origins. Individuals diagnosed with PWS need enhanced supervision to address the
