In garden peas, the allele for tall plants (T) is dominant over the allele for dwarf plants (t). A true-breeding tall plant is bred with a true-breeding dwarf plant to produce heterozygous tall plants. The F1 heterozygotes then self-fertilize to yield F2 offspring. Complete the Punnett square for this monohybrid cross using the F1 gametes with the appropriate genotype and placing the correct F2 genotype/phenotype combination in the Punnett square. Male gamete TT Tall Tt Tall Female gamete Tt Tall tt Dwarf For each of the following. determine the probability that a child will be affected with the given condition. Consider the following genotypes and phenotypes:BB, Bb, yellow(normal) urinebb, beeturia(red urine after eating beets)HH, Hh, colored eyelidshh, normal eyelidsEE, Ee, brachydactyla(short fingers)ee, normal fingers1. If a man and woman both have a genotype Ee, then what is the probability that their child wii have normal fingers?2, If a man has a normal urine and genotype Bb and woman has beeturia and genotype bb what is the probability that the child will have beeturia fingers?3. What is the probability that their child will have colored eyelids?4. What is the probability that their child will have colored and beeturia eyelids?

Explanation:

TT ×tt

I

Tt Tt Tt Tt

Where Tt Tt Tt TT are the genotype for the first filial generation.

To generate the 2nd filial generation, we self the 1st generation.

Tt × Tt

I

TT Tt Tt tt

We have TT Tt Tt tt as the second filial generation.

If a man and a woman both have Ee the probability that the child will have normal finger is 1/4

Ee × Ee

I

EE Ee Ee ee

Where EE, Ee is brachydactly and ee is normal finger.

When a man with normal eye is crossed with a man with beeturia the probability of having a child with beeturia 2/4

Bb × bb

I

Bb bb Bb bb

Where BB Bb is normal eye and bb is beeturia

When a man with colored eye lid HH is crossed with normal eyes lid hh the probability of having a child with color eyes lid is 1

HH × hh

I

Hh Hh Hh Hh

Where Hh represent normal eyes lid

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)

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
