below and answer the follow-up questions. Questions: 1. According to the pedigree‚ is cystic fibrosis inherited as a dominant or as a recessive trait? Explain how you made your conclusion using evidence from the pedigree and the principles of genetics. The pedigree shows that cystic fibrosis is a recessive trait. This is shown by having one cystic fibrosis gene and having one non-cystic fibrosis gene. Now this can mean that you may be the carrier of the disease‚ but not actually have the

pedigree‚ is cystic fibrosis inherited as a dominant or as a recessive trait? Explain how you made your conclusion using evidence from the pedigree and the principles of genetics. -Cystic fibrosis is inherited as a recessive trait. Each child of 2 carriers has a ¼ chance of inheriting 2 recessive alleles. A person with 2copies of this allele has cystic fibrosis. 2.

Explain how you made your conclusion using evidence from the pedigree and the principles of genetics. Cystic fibrosis is a recessive trait. If you have one CF gene and one non-CF gene‚ you will be a carrier but not have CF. I referred back to Mendel mentioning that the trait

Prophase 1 of meiosis When prophase I occurs the chromosomal condensation enables the chromosomes to be looked at under the microscope. Then during late prophase I the homologous chromosomes laterally pair or usually side by side which is then known to be in synapsis this is when cross connections form from Breakage and re-joining between the chromatids which can occur between the pair homologous chromosomes which then lead to genetic combination between the strands which are there. Chiasma occurs

diseases can be classified by several different things‚ such as the organ involved‚ the pattern of the symptoms‚ or the cause of the disease. There are a variety of respiratory diseases‚ such as bronchiectasis‚ chronic obstructive pulmonary disease‚ cystic fibrosis‚ empyema‚ mycoplasma pneumonia‚ pleurisy‚ and lung abscesses.

can also affect a person’s health in different ways. For example‚ if someone is diagnosed with cystic fibrosis‚ the humanistic approach says that for someone to develop‚ a person must follow through Maslow’s hierarchy of needs where they must achieve the basic necessities of life fists such as good housing‚ good quality food and health which are all included in Maslow’s hierarchy of needs. Cystic fibrosis is an incurable disease‚ which means that once an individual has been diagnosed with the disease

P2: Explain the potential effects of five different life factors on the development of an individual Fetal Alcohol Syndrome FAS is the term used to describe a number of foetal abnormalities which occur in the babies of women who have abused alcohol during the course of their pregnancy. If a woman drinks alcohol during pregnancy the alcohol goes across the placenta to the foetus through the bloodstream. The foetus’ liver isn’t fully formed‚ so it cannot metabolise the alcohol quickly enough‚ therefore
