Introduction The genes of an offspring can be determined by the characteristics shown which are called phenotypes Once the phenotypes have been observed then the genotypes of the offspring can then be determined These traits or characteristics are inherited from the parent The different genes that are given to the offspring by the parent have two factors known as alleles for each gene Information in the two alleles may be different These alleles can either hold a recessive gene or a dominant gene This will then define the offsprings phenotype Barley plants contain a gene controlling pigment that shown by different alleles If the barley plant produces green plants then the dominant pigment is present in one allele But if the plant is whitealbino then it shows that there is a recessive gene and no pigment was produced If a green plant is produced then it is able to photosynthesise rather if an albino plant was to be produced the plant would lack chlorophyll and will therefore die as a young seedling Aim--HypothesisIt is expected that the plants containing pigmentation chlorophyll will have a higher and faster growth rate compared to the plants that do not contain pigmentationEquipmentPunnet squareBarley seedsWaterMatch sticks paddle pop sticksSpray bottleSoilGrowth matRulerRisk assessmentRiskLevel of Risk 1-10ManagementInhaling Potting Mix Legionnaires disease8Wear a maskMethodCollect all equipmentFill punnet with potting mix place two seeds in each individual punnet squarePush seeds deep into the potting mixAdd layer of potting mix over the top then waterNominate four plants to measure for the weekWater each day and measure the four nominated plantsPut all measurements in a table for each dayResultsTable 1 Growth resultsMondayTuesdayWednesdayThursdayFridayGreen 17 cm76cm8cm82cm88cmGreen 216cm165cm17cm173182cmAlbino 18cm 83cm89cm93cm94cmAlbino 281cm85cm87cm88cm89cmTable 2 Year 10 punnet square resultsNumber of dark green plantsNumber of light green plantsNumber of albino plants of dark green plants of light green plants albino plantsYAB6701186014BIM - A7601584016WIS7001880020BIM - D670889011Total 28005284301566DiscussionIt is evident from the phenotypes of the barley plants in the group
