Video Exam


  • Survival of the fittest is shown in a couple of ways in the clip. 
  • A pack of lionesses attack the slowest, youngest buffalo for food.
  • The faster buffalo get away because they are faster. 
  • When the buffalo returned, they outnumbered the lionesses, which allowed them to rescue the baby buff.
  • The buffs were heavier which made it difficult for the buffalo to obtain and kill one. 
  • Both, the buffalo and lionesses, almost lost the baby buff to the crocodile which was swimming in the lake.

CHAPTER 14 SUMMARY

14.1 
karyotype-a picture of chromosomes arranged in a certain way.
Sex chromosome-two of the 46 chromosomes in human body.
Autosome-thermae 44 chromosomes in the human body.
pedigree-shows the relationships within the family.

What is the difference between an auto zone and a sex chromosome?
Sex ones determine if it's male or female
What is a karyotype and how was it used?
Biologist photographs cells in mitosis and cut them into them together.
What is the pedigree? How does it explain inheritance type?
It shows how we treat is transmitted through three generations of the family.

14.2
Sex-linked genes-special pattern of inheritance for genes located on the X and Y chromosomes.
Colorblindness-an inability to distinguish certain colors.

Down syndrome.

14.3

Restrictions on-protein the breakdown the DNA even me
Gel Electrophoreses-a way to separate DNA fragments
Gene therapy-in gene therapy and absent or faulty gene is replaced by normal working.

to decode the human genome
What is gene therapy?
genes that was broken are replaced with healthy worrking genes.
