What Makes Us Who We Are
You're unique. No two people are exactly alike.
Your genes contain DNA which determines all your traits, and exactly what you will be like.
Parents to offspring
You get half your DNA from your mom and the other half from your dad.
What Are Chromosomes and How Are They Passed Down?
When DNA Passed Down to Offspring Is... Well... Different!
Maria and Lucy Aylmer
There are many twins that are born to their parents that have different races, while their parents share different races two. But aren’t the children supposed to be a mixed race? in Lucy and Maria Aylmer were born on January 1997, as a 2015 study stated that the twins who are born not as identical to their sibling inherit different genes as they come from separate eggs. Their mother, Donna, carries genes for black and white skin, but the offspring have inherited separate genes for color.
The Durrant Family
News from another family in March 2015, the Durrant family had two sets of twins, which were seven years apart, that had different colored skin (mixed-race twins). Scientists say that this a 2 in a million occurrence, and that their genes were separated based on their family gene pool.
- Prophase I- The chromosomes condense, and the nuclear envelope breaks down. crossing-over occurs.
- Metaphase I- pairs of homologous chromosomes move to the equator of the cell.
- Anaphase I- Homologous Chromosomes move to opposite polls of the cell.
- Telophase I and Cytokinesis- Chromosomes gather at the poles of the cells. the cytoplasm divides.
- Prophase II- a new spindle forms around the chromosomes
- Metaphase II- Chromosmes line up at the equator.
- Anaphase II- Centromeres divides and chromatids move to opposite polls of the cells.
- Telophase II and Cytokinesis- a nuclear envolope forms around each set of chromosomes. The cytoplasm divides.
Diseases Linked With Genetics
Components that make up genetic code are common to all organisms, but there are a lot of diseases that are linked with genetics. The most common types of genetic diseases are cystic fibrosis, Down syndrome, Huntington’s disease, and hemophilia.
Every male gets an X chromosome from his mother and a Y from his father. Diseases inherited in an autosomal dominant pattern require only one genetic mutation to cause symptoms. Diseases inherited in an autosomal recessive pattern require two genetic mutations (one from each parent) to cause symptoms. Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured. However, approaches may be available to treat or manage some of the associated signs and symptoms. When disorders are passed down to twins,
