Eric and janelle are both carriers of the recessive allele causing tay-sachs disease, which is lethal in early childhood. if they have a baby, what is the probability that this child would have tay-sachs disease?

25% would have tay-sachs disease, 25% normal, 50% carriers

hey, what do you need . just post the question and i may be able to you : )

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)
