Answer:
The bipedality
Explanation:
<u>One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size</u> because Lucy actually had a small skull which could indirectly be translated to small brain size.
NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.
During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs.
Answer: The female is a carrier for hemophila, since the parents are phenotypically normal and The Turners syndrome is caused by an error which caused the missing chromosome to dissapear duting oogenesis (egg prodiction) or spermatogenesis (sperm production)
Explanation:
Hemophila is an X-linked recessive disease an in this case has complete penetrance ie. The phenotype will be expressed.
Here the parents do not express hemophilia thus indicating that the mother (this is an X-like recessive disease) expressess hemophila on the recessive X chromosome
Turners Syndrome is caused by chromosomal non-disjunction during oogenesis or spermatogenesis.
