Southwest CTA. The research was organized to find the allele and genotype frequency of people who use their right hand versus their left hand. The data showed that the dominant allele was more frequent than the recessive‚ and the genotype frequencies amongst the three were not equal. After studying the chi-squared tests‚ we have decided to reject the null hypothesis because there was a significant difference across the three genotypes. __________________________________________________________________________

Answer: Genotypes: FF ¼‚ Ff ½‚ ff ¼ Phenotypes: Freckles ¾‚ No freckles ¼ Part 2: Dihybrid Cross—Predicting Flower Color and Seed Shape Imagine that you are crossing two plants that are heterozygous for flower color and seed shape. The dominant and recessive alleles for these traits are as follows: purple flowers: P white flowers: p round seeds: R wrinkled seeds: r (2 points) 1. Determine the genotype of each parent

Abstract The plant Brassica rapa is a fast plant most commonly known as the field mustard. The plant itself particularly well known for its extremely fast rate of growth‚ making it easy to breed and cross pollinate several generations. Due to its ability of rapid growth it has become a favorite for scientist to test the theories of inheritance on. In our case we tested to see if we could affect the overall hairiness of different generations. F1 seed was ordered‚ germinated and cross-pollinated

Fill in the genotype of the offspring in each box by combining the genotype of sperm in its row with the genotype of the egg in its column. (Multiply the fraction of sperm of each type in the row headers by the fraction of eggs of each type in the column headers.) 5. Count the number of offspring with each genotype. (Note that Pp is the same as pP.)

The two techniques that were used to create a DNA profile in this experiment were PCR and gel electrophoresis. The PCR is used to amplify the several DNA samples and gel electrophoresis is performed to separate the DNA fragments according to their size. [6] In the first part of the experiment‚ PCR amplification of the DNA templates was performed and the products obtained were used to perform gel electrophoresis. The process of PCR allows for the amplification of the DNA samples and the components

and meiotic drive. Frequency is the proportion of individuals in a certain category relative to the total number of individuals considered. The frequency of an allele or genotype is expressed as a decimal proportion of the total alleles or genotypes in a population. For example‚ if 4 individuals in a population of 16 are genotype Bb‚ the frequency of Bb is 0.25 (calculated by dividing 4 by 16). If 75 out of 100 alleles in a population are B then the frequency of allele B in the population is 0.75
