Mendelian genetics Flashcards
(8 cards)
what are genes
information passed on from parents to offspring if information is packaged as discrete particles
how many copies of each gene does a offspring have
2 copies - one from each parent
what are alleles
different forms of a gene as genes controlling a trait can differ
what is a locus
the specific position where the genes for a particular trait resides
what is the reason for a test cross
to find the missing allele
what are Mendel’s law explained by
both laws are explained by chromosomal behavior during meiosis
what is Mendel’s 1st law
law of segregation
Genes segregate at meiosis so that each gamete contains only one one of the 2 passes by the parent
what is Mendel’s 2nd law
law of independent assortment
Alleles of different genes assort independently during gamete formation
