Mendel and genetic diagrams/disorders

Question 1

Who was he?

what was the height ratio?

Answer 1

Austrian monk experimented on pea plants different heights,leaf colours,flowers etc
foundation of modern genetics
3:1 tall:small

Question 2

Name the 3 things he found out?

Answer 2

Each trait determined by gene
Each characteristic is inherited separately
You inherit 1 gene from each parent and the intensity of the trait depends on the whether the gene is DOMINANT or recessive.

Question 3

Why did some ppl ignore his work?

Answer 3

no background knowledge to properly understand it-no one knew about genes DNA chromosomes
new and advanced for them

Question 4

Name some sex linked disorders and explain why it happens?

Answer 4

conditions that affect males more than females
genes for these conditions are carried on X chromosomes as Y chromosome shorter there is no matching allele to prevent the condition

Question 5

Name the allels controlling blood groups?
explain these keywords
codominant
gamete
haploid
diploid
gene
mutation
meiosis
mitosis
allele
zygote
phenotype
genotype

Answer 5

A,B,O
A B codominant neither allele is dominant over the other

haploid cells produced thro meiosis e.g sperm egg
normal num of chromosomes in an organism
half the normal num of chromosome in organism
a section of DNA
a rare random change in DNA code that alters message carried by that gene
cell division ,4 haploid daughter cells are produced
cell division ,2 new daughter cells produced g identical to parent cell
diff version of the same gene
a fertilised egg
the affect alleles have on you determine characteristics
combination of alleles you have
