Genetics Study Guide- Bio 2023 Flashcards
heredity passed from parent to child made up of sequences of DNA and arranged one after another
Gene
one of different forms of a gene
allele
Aa or Dh
heterozygous
AA
homologous
the offspring of two plants or animals of different species or varieties
Hybrid
1/2 of a chromsome
Haploid
full chromosome
Diploid
what did Mendel use for his experiments
pea plants
Mendels 4 big ideas
1) inheritance is determined by genes
2) some alleles may be dominant and others are recessive
3) law of segregation
4) alleles for different genes usually segregate independently of each other
Mendels 4 big ideas

3) law of segregation
4) alleles for different genes usually segregate independently of each other
idea that genes are inherited independently of each other which means that if one parent carries a gene dominant over the other than there’s nothing the other parent can do about it.
law of assortment and how it affects inheritence
the presence of a dominant allele will always mask the presence of a recessive allele
principle of dominance
dominance affects the phenotype derived from an organisms genes, but it doesn’t affect the way these genes are inherited
how does the principle of dominance relate to geno and pheno types
a measurement tool that helps predict the chances of an offspring being inherited with a particular trait of interest.
probability and how its used in genetics
gamete
reproductive cell of an animal or plant
