monogenic inheritance Flashcards
(11 cards)
what is allele
a version of a gene
what is heterozygous
not true breeding
having both dominant and recessive alleles at a gene locus on a chromosome
what is homozygous
true breeding
having identical alleles, either 2 dominant and 2 recessive alleles on a pair of homologous chromosomes.
what does monogenic mean
when something is determined/ controlled by a single gene
who begun genetic research in 1866
gregor mendel
why did gregor study pea plants
pea plants are;
easy to grow
self fertilising
cross fertilisation is easy
who created the monohybrid cross
gregor mendell
what are the three type of genotype
homozygous recessive or dominant
heterozygous
what is important to remember in a punnet square
always circle the gametes
if offspring are 100 percent heterozygous, what does that mean about the parents genotypes
1 parent is homozygous dominant while the other is homozygous recessive
what do you call the parental generation and the offspring
parent- p1
offspring- f1
