Lesson 9 - Multiple Alleles and Polygenic Inheritance

Question 1

multiple alleles

Answer 1

many genotypes and phenotypes for a single trait

Question 2

antigen

Answer 2

carbohydrate on the red blood cell

Question 3

genotypes and phenotypes of the four blood types

Answer 3

O - ii
A - IAIA and IBi
B - IBIB and Ibi
AB - IAIB

Question 4

which blood would cause which to clot, which are universal donors and universal acceptors

Answer 4

O - A,B,AB
A - B, AB
B - A, AB
AB - none

universal donors - O
universal acceptor - AB

Question 5

antibody

Answer 5

proteins that protect you when an unwanted substance enters your body

Question 6

how can blood infusions go wrong

Answer 6

if given the wrong blood your immune system could see the new blood as a foreign and will try and destroy it.The immune system will use antibodies to bind the new blood together and cause a clump

Question 7

examples of environmental factors effecting inheritance

Answer 7

leaves and flowers of plants - living conditions (sun, nutrients)
animal coats - black fur for colder climates, white fur for warmer climates

Question 8

polygenic traits

Answer 8

many traits controlled by more than one gene
