5 Helpful Tips for Teaching Genetics

Here is #2 for my “5 Helpful Tips” series. If you missed the first one, check out 5 Helpful Tips for Teaching Photosynthesis. Genetics is one of my favorite things to teach *cue sparkly harp music*. I really look forward to teaching genetics! And one thing that makes it so fun for me is discussing human genetics. Here is a complete list of human genetic myths that you can read for your consideration. Busting Student Misconceptions: Students tend to struggle with some terminology — it can be really difficult for students to differentiate between terms such as DNA, gene, and allele.

Six creative ways to teach genetics. Genetics. Introduction to Heredity and Traits. The 2004 publication Investigating Safety: A Guide for High School Teachers by Texley et al. has raised an alarm in the teaching community about the usefulness and safety of PTC taste testing.

Introduction to Heredity and Traits

This has led to PTC being banned from many schools and districts - we believe unnecessarily. Yes, PTC is toxic. In rats, the most sensitive animals tested, the oral LD50 of PTC (the amount that killed 50% of test animals) is 3 mg/kg. However, PTC is so intensely bitter that tasters can detect it in miniscule quantities. A single test paper from Carolina Biological Supply contains just 0.007 mg of PTC. First identical twins with different skin colour born in the UK  Identical twins Amelia and Jasmine are thought be the first black and white twins born in the UK, despite coming from the same egg.

First identical twins with different skin colour born in the UK 

The girls were born to mum Libby Appleby, 37, from West Rainton, County Durham who is white and her partner Tafadzwa Madzimbamuto, 40, who is black. They are identical or monozygotic twins, meaning they developed from the same zygote, which split and formed two embryos. Scroll down for video Libby Appleby, 37, from West Rainton, County Durham was told she wouldn't be able to tell her identical twin babies apart. But Jasmine (left) and Amelia were born with contrasting skin tones Elder twin Amelia (right) has dark skin, black hair and brown eyes, her sister Jasmine has fair skin, blue eyes and mousey curls Monozygotic twins are always the same sex, share identical blood groups and genetic make-up and always closely resemble each other.

When the girls were born Libby and her partner were flabbergasted, and even the doctors couldn't believe it. Loaded: 0% Why Women Are Stripey. Sex determination: More complicated than you thought - Aaron Reedy. Most mammals, like humans have an XY genetic system for determining sex where XX produces females and XY produces males.

Sex determination: More complicated than you thought - Aaron Reedy

However, sometimes when sex chromosomes are dividing during meiosis, non-disjunction occurs and embryos are formed with numbers of sex chromosomes different from those that are typical. For example on occasion males have the sex chromosomes XXY or XYY. There are also sometimes females with a single X chromosome or an XXX combination of sex chromosomes. There are even sometimes individuals who are genetically XY, but due to male hormone insensitivity, develop some or nearly all female characteristics. Research some of these cases in humans.
