The barley plant has seven pairs of chromosomes. For a gamete, the number of genetic combinations that are possible through independent assortment is _. For a zygote produced by two barley parents, the number of possible genetic combinations is _. Answers:
1. 128
2. 16,384

I hope this helps.

1. 128

2. 16,384

Explanation:

Imagine there were two pairs of chromosomes:

A paired with B

C paired with D

A gamete could have the following combinations:

A + C

A + D

B + C

B + D

Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities

With seven pairs of chromosomes, there are  (2⁷) possibilities. 2⁷  = 128

For a zygote produced by two barley parents, there are two gametes fused. So we must multiply the number of combinations for each gamete. Therefore, number of possible genetic combinations is 128 x 128 = 16,384

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
