Answer:
3 and 4 are both Aa
8 and 9 cannot be h0m0zygous.
Explanation:
Individual 3 and 4 are non-shaded, which means they are either AA or Aa.
They have three children, 9, 10, and 11. 9 and 11 are also non-shaded, meaning they are either AA or Aa.
However, 10 is shaded, which means he is aa.
For 10 to be aa, he must have gotten one a allele from each parent. Therefore, 3 and 4 must both be heterozygous Aa.
8 and 9 are both non-shaded, which means they are either AA or Aa.
They have three children, 13 is non-shaded, so either AA or Aa.
12 and 14 are both shaded, which means they are both aa. They much each have inherited an a allele from each parent.
This means it is impossible for individuals 8 and 9 to be h0m0zygous.
The answer is the mitochondria. They have their own DNA unlike other organelles.
Answer:
yes the statistics vary for example in Sub-Sahara Africa it is 2/3 more prevalent than anywhere in the world.
Explanation:
Xylem tissue helps in the transport of water and minerals. Phloem tissue helps in the transport of food. Transport in xylem requires physical forces such as transpiration pull. Transport of food in phloem requires energy in the form of ATP.
Answer:The digestive system uses mechanical and chemical methods to break food down into nutrient molecules that can be absorbed into the blood. Once in the blood, the food molecules are routed to every cell in the animal's body. There are two types of animal body plans as well as two locations fordigestion to occur.
