The information below represents two sets of data collected from the above cross.
Phenotypes Data Set 1 Data Set 2 Regular Red 26 846 Regular Yellow 15 273 Potato Red 6 287 Potato Yellow 12 94 Total 59 1 500In the previous question, you determined the expected phenotypic ratio if the genes for leaf shape and fruit colour are on different chromosomes and assort independently during gamete formation.
Convert the expected phenotype ratio into the expected probability for each of the four phenotypes and record them in the table below. (Record your answers as a value between 0 and 1 rounded to two decimal places.) (1 mark) Data set 1 and 2 are the actual data observed from the cross. Calculate the observed probability of the four possible phenotypes for each data set by dividing the number of progeny in each class by the total number of progeny and record these in the table below. (Record your answers as a value between 0 and 1 rounded to two decimal places.) (2 marks: 1 mark for each data set)Probability = Number of Progency in Phenotype class Total Progeny

Faulty Tooth Enamel Formation Amelogenesis imperfecta (AI) is a disorder of faulty tooth enamel formation that involves 2 genes. The expression of AI disorder is determined by mutations in an autosomal gene. One copy of the mutated allele (A) will cause the disorder. Thus, the expression of AI disorder is inherited in an autosomal dominant pattern. In individuals that have the AI allele (A), the severity of the disorder is determined by mutations in a gene carried on the X chromosome. The non-severe allele (XN) is dominant over the severe allele(Xn). In the absence of the autosomal dominant allele (A), the abnormality gene on the X chromosome is not expressed. In other words, individuals that are homozygous recessive for AI are normal, no matter what allele they have on the X chromosome. Question: A woman with normal teeth had four children with a man with the non-severe form of AI as follows:
a boy without amelogenesis imperfecta, a girl without amelogenesis imperfecta a boy with severe amelogenesis imperfecta a boy with non-severe amelogenesisIdentify the parental genotypes. (1 mark) Complete the Punnett square for the parental cross, and identify the possible phenotype ratios of the children. (2 marks)

Two general types of life strategies allow species to thrive in varying types of environment: r-selected strategy and K-selected strategy. Given the following biomes, identify the life strategy that would be more successful in surviving the environmental conditions and provide an explanation supporting your answer.
