Chapter 7 - Mendel and Monohybrid Inheritance Flashcards
1
Q
Who was Mendel?
A
A monk from the Czech Republic, the father of genetics
2
Q
What were the principles behind his work?
A
- reproducing lots of experiments
- controlled pollination
- tracking which characteristics were reproduced
- using maths to prove ratios of characteristics
3
Q
How did other scientists rediscover his work?
A
publishing articles and peer reviewing
4
Q
What are alleles?
A
alternatives forms of genes e.g brown eyes vs blue eyes
5
Q
what does monohybrid inheritance mean?
A
1 type of characteristic
6
Q
what does homozygous mean?

same allele (e.g. tt or TT)
7
Q
what does heterozygous mean?
A
different alleles (e.g. Tt)
8

dominant gene
9
Q
What does a lowercase letter represent?

recessive gene
10
Q
what is a phenotype?
