BIO 305 EXAM QUESTIONS AND ANSWERS 100% VERIFIED
Central area of biological research is. - ANSWER what makes an organism the way it
is?
gene discovery - ANSWER find the subset of genes in the genome that influence a
property
single-gene inheritance patterns - ANSWER?????
gene crosses - ANSWER gene matings
mutants - ANSWER individual organisms having some altered form of a normal
property
wild type - ANSWER that which is found "in the wild"
genetic dissection ANSWER the use of mutants x wild type to analyze a gene/biological
property
how to hunt for mutants - ANSWER screen a large number of individuals,
Gregor Mendel - ANSWER determined rules for single-gene inheritance in 1860s, monk
character/trait/property - ANSWER color, height, blah blah
phenotype - ANSWER form taken by a character, ("yellow")
, pure lines - ANSWER all offspring produced by matings within the members of that line
are identical (all yellow-seeded mating produced yellow seeds)
self-mating - ANSWER flower pollinates itself
parental generation - ANSWER first cross comes from
firs filial generation (F1) - ANSWER children of first cross (progeny generation)
Chromosomal theory of inheritance - ANSWER chromosomes carry genetic material.
1902, Walter sutton watched meiosis in grasshopper cells - Mendel's ratios correlated to
chromosome segregation
Thomas Hunt Morgan - ANSWER worked with flies as a model - lots of kids, short
generation time, 4 chromosomes. skeptical of chromosome theory
studied sex-linked genes
autosomal gene - ANSWER NOT sex-linked allele (x-linked)
F1 of monohybrid cross autosomal gene - ANSWER all dominant phenotype
reciprocal cross - ANSWER 2 crosses with opposite phenotype on sexes -- used to
identify sex-linked genes
# of genes on sex chromosomes - ANSWER 30-100 on Y, about 20X more on X
how did Y chromosome evolve - ANSWER degeneration of X chromosome
