Inheritance Flashcards
What is a alleles
It is a different form of the same gene
Like eye colour
What is mitosis
It is when a cell is split into two identical daughter cells
What is a chromosomes
Thread like structures carrying the genetic information found in nucleus
What is differentiation
It happens in early development of an embryos when the cells are unspecialised and can become any type of cell needed
Stem cells
Meiosis is ….
When four cells are made with half the genetic information
These are gametes or sex cells
They only have 23 chromosomes
Variation is caused by…..
Meiosis means that no cell is the same which introduces variety as each gamete is different
What is the function of stem cells
To form all the specialised cells we need
What are stem cells used for
Scientists hope that they will be able to create tissues and use it to replace it and grow organs
Problems with stem cells research
They come from embryos and this cases augments about when life begins
How was Mendel
Mendel was a monk
He became a monk for an education
He was the first to record his results.
What was Mendel discoveries
When he breed green and yellow peas second offspring was 1/4 green
About the genetic code
Two strands
Made out of hundred is bases
One change or mutation can disrupt the whole protein structure
Homozygous
To identical alleles
RR BB
Heterozygous
Different alleles
Dd Bb
Genotype
Describes genetic makeup regarding particular characteristics
GG Dd
