Answer correctly 50 Points
Natali [406]

1. The main aim of the Human Genome Project was to determine the DNA Sequence of every human gene.

2. Variation in skin colour is an example of polygenic inheritance

This Human Karyotype is unusual because it has an extra chromosome at chromosome 21.

Klinefelters syndrome is shown in the second figure

Explanation:

1. The Human Genome Project's main goal was to sequence all the 30,000 genes and 3 million base pairs in their makeup for the early detection of diseases, gene therapy and molecular level studies.

2. Human skin colour is determined by the pigment melanin. The Dominant allele is responsible for dark colours as it produces more melanin. The melanocortin 1 receptor (MC1R) gene and Tyrosinase enzyme codes for the human skin colour. Polygenic inheritance are the traits which are controlled by one or more genes.

<u>figures:</u>

<u>The extra chro</u>mosome at the 21st chromosome pairs is called trisomy 21 or Down's Syndrome. It is due to the abnormal cell division/meiosis resulting in an extra X chromosome. This leads to thechanges the in physical development of  the individual.

Klinefelter's Syndrome: There are 47 chromosomes and 2 or more X chromosomes in this syndrome of males. The resulting male suffering from Klinefelter would be sterile and have poorly developed testicles.

faced a struggle for survival

comparative profile for covid-19 cases from china and north america: clinical symptoms, comorbidities and disease biomarkers
Hatshy [7]

Different people are affected by COVID-19 in various ways. The symptoms experienced by infected individuals have ranged widely, from little discomfort to serious sickness.

  • The susceptibility to and prognosis of severe acute respiratory syndrome caused by coronavirus 2 or coronavirus disease 2019 (COVID-19) have been found to vary greatly amongst individuals and populations.
  • Intervention in public health must take into account these variations and how they affect susceptibility to infection and the severity of disease.
  • The distinctions between the COVID-19 case profiles from China and North America may be due to regional variations in host, environmental, and healthcare-related factors.
  • These inter-population variances, together with intra-population variability, highlight the need to identify how health inequities and inequalities affect the public health response to COVID-19 and can help with preparing for the epidemic's resurgence.
