Study guide for chapter 10.2 and 10.3

trait, homozygous, heterozygous, hybrid, genotype, phenotype, law of segregation,
law of independent assortment, genetic recombination, polyploidy, chromosome

Be able to do a one trait cross, especially a monohybrid cross.
Be able to do a two trait cross, especially a dihybrid cross.
Be able to do these crosses using a Punnett square or algebra.
Know the difference between probability and ratio.
Be able to determine if genes are linked on the same chromosome from
experimental data given. If they are linked, then be able to determine the
distance between genes in map units.
Study guide for chapter 11.1 and 11.2 (plus small section of 11.3)
Know the following vocabulary: carrier, pedigree, incomplete dominance,
codominance, multiple alleles, epistasis, sex chromosomes, autosomal
chromosomes, sex-linked trait, polygenic trait
1. Be able to design and interpret a pedigree chart for autosomal dominant,
autosomal recessive, sex linked dominant, and sex linked recessive traits.
2. Be able to understand when a trait is incompletely dominant.
3. Be able to explain why the allele for sickle-cell trait has existed for so long in
the human population.
4. Be able to determine blood types given parental blood types. Be able to
determine if the individual is a good donor or recipient for a particular type
of blood.
5. How does polygenic inheritance work? Examples?
6. What is a karyotype? When are the chromosomes photographed?
7. Why do people survive with a polygenic 21st chromosome yet do not when it
is one of the first chromosomes?
8. How are fetal tests done? What can each of the three do? Risks?
