◉ determination of karyotype
Answer: amniocentesis and chronic villi sampling
◉ Turner syndrome
Answer: -X
-female
-short height
-web of skin between neck and shoulders
-underdeveloped ovaries
-some learning difficulties
◉ Klinefelter syndrome
Answer: -XXY
-male
-underdeveloped testes
,-lower testosterone levels
-development of some female features
-long limbs and slightly taller than average
◉ XYY Male
Answer: -taller than average
-moderate to severe acne
-intelligence may slightly lower than average
-sometimes called "super males"
◉ XXX Female
Answer: -may be sterile
-no obvious physical or mental problems
-sometimes called "metafemales"
◉ blending "theory" of heredity proposed that
Answer: -hereditary materials of parents are mixed in offspring
-offspring's traits are intermediate
◉ consequences of blending "theory" of heredity
Answer: -individuals in population reach a uniform appearance
, -after blending, traits can no longer be separated out to appear in
later generations
◉ Gregor Mendel
Answer: particulate theory
◉ particulate theory
Answer: parents transmit discrete inheritable factors(genes) that
remain separate through generations
◉ true-breeding
Answer: always produce offspring with the same trait as parents
when parents are selfed
◉ Mendel's results
Answer: -hereditary factors remain intact from one generation to
the next
-genes may have more than one form(alleles)
-each pea plant has two alleles, one from each parent
◉ homozygous
Answer: has two identical alleles for a character
