Inheritance Flashcards
What is inheritance controlled by
Alleles
What did Gregor Mendel propose
He proposed that the mechanism of inheritance gave a rise in science genetics
What happens if the alleles are the same
The characteristic is shown by the plant
What happens if the alleles are different
The characteristics are shown by the dominant alleles
How many alleles do gametes carry
Two
What is a genotype
The genetic make up of an individual I.e. which alleles it has
What is a phenotype
The way the gene is seen or expressed
What does dominant mean
Their character which shows the heterozygote
What does recessive mean
The character which is masked in their heterozygote
What does F1 and F2 mean
Their first F1 and the second F2 generations in a genetic cross
What is selfing
Self fertilisation
What is heterozygous
I need individual that has two different alleles of a particular gene
What is heterozygote
A heterozygous individual
What is a Punnett square used for
To predict the genotypes and phenotype that result from a particular cross
