INVESTIGATION OF THE INHERITANCE OF THE ROSETTE GENE IN BRASSICA RAPA By: Justine Poorbaugh Foundations of Biology 2 Laboratory Thursday 2:30 PM Professor Cheek April 21‚ 2011 ABSTRACT The Brassica rapa is a rapid growing plant that has a standard form and a mutant rosette form. Relative to normal plants‚ the rosette form is shorter and takes longer to flower. The mode of inheritance of the rosette gene was tested by crossing two true-breeding plants‚ one of each form. The F1 generation

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle

Examining Mendel’s “First Law”: Observing Anthocyanin in Brassica rapa Abstract The foundation of genetics lies with the principles that Gregor Mendel outlined after his experiments with pea plants where he discovered the relationship between physical characteristics‚ or phenotype‚ and genetic traits‚ or genotype. This experiment aimed to reproduce Mendel’s results with the Brassica rapa plant‚ noted for it’s fast generation time‚ and anthocyanin‚ a purple pigment that can be visually tracked

Abstract The purpose of this experiment was to determine the correlation between the ability to taste the bitterness of phenylthiocarbamide‚ an organic compound used in genetics‚ and the ability and response of the tasting sodium benzoate paper‚ a food preservative. It is claimed that there is a direct relationship between the genes that control the tasting abilities of these two substances‚ primarily that if you had the ability to taste PTC‚ you would have a specific taste response for sodium

Survey at least 20 people to find out what traits they have for each of the features below. Tally the numbers for each trait and record those totals in each column. When completing the survey‚ be sure to include yourself as one of the individuals surveyed. Also include at least one set of parents and offspring in the individuals you survey. Document the features of each member of the family you surveyed within the data table‚ but also make a special note of these features in the observation section

1.) In a plant having two carried alleles for the color of a flower in a gene‚ with P for purple and p for white‚ the three possible combinations which might exist in any one plant are PP making a purple plant‚ pp to make a white plant‚ or Pp resulting in a ‘hybrid’ plant. 2.) Out of the genotypes PP‚ Pp‚ pp‚ the resultant flower colors are (as described above in exercise 1) are purple (for PP‚) purple or purplish-white (for Pp- likely purple as it is dominant‚ or a mixture of the colors‚) or white

Mendel’s approach to answering scientific questions was highly focused. He chose just a handful of traits to study‚ seven to be exact‚ and by doing so was able to more easily keep an accurate mathematical record of each of the traits and how they carried to subsequent generations. The approach that he took‚ looking at a lesser quantity of traits‚ gave him an advantage because he was able to realize a higher quality of information from his research. The simplicity of it gave him more control over

Marissa Lule Isaac Cuevas Juan Arias Andres Santana per.4 4/20/15 Pedigree Lab Introduction How can you spot different pattern of inheritance? When we started this lab the question (subject) we had to try and solve was ‘Which pattern of inheritance is present in the O’Smithsteinskis and AkimGarciaChan family pedigree? If when looking at the number of people shaded in our pedigree and find that the number is increasing each generationon then we can assume that the p

Discussion: Referring to the hypothesis we predicted in the beginning of this experiment that under ideal conditions‚ we hypothesized that the results will eventually follow the Hardy-Weinberg expectations‚ which means the genotypes frequencies of the Drosophila melanogaster would remain constant; Therefore‚ no evolution had happened to the flies under the ideal conditions. After the chi-squared values were found in each week (table 1)‚ in the third generation where the chi-squared was found to

Genetics Problems 1. Brown eyes are dominant over blue. What are the chances that the first child of a marriage of two hybrid (heterozygous) brown-eyed parents will be blue-eyed? What are the chances of the second child being blue-eyed? BB Bb Bb bb There is a 25% chance that the first child will be blue-eyed and a 75% chance the child will be brown-eyed. There is a 50% chance that the trait for brown eyes will overpower the recessive trait for blue eyes. 2.In humans‚ color-blindness
