PLZ type the answer for question one so I can read it easily. huge thumbs.

1-What are autologous cells, their benefits, and drawback

2- A man and a woman walk into a genetic counselor’s office. The woman has a brother who has been diagnosed with hemophilia, a sex-linked condition. The man has no family history of the illness. They are considering having children. Which of the following statements are appropriate and correct things to say to this couple?

1-The chance of any given child from this couple having hemophilia is approximately 50%

2-Assuming the woman and her afflicted brother have the same mother, the chance of a male child from this couple having hemophilia is approximately 25%

3-The chance of a female child from this couple having hemophilia is approximately 50%

4-An egg donor might be a good idea, if they are open to the idea

5-A sperm donor might be a good idea, if they are open to the idea

6-The two should probably adopt, and not spread their bad genes

The height of a type of bean plants is determined by five unlinked genes called A, B, C, D, and E. Each gene has two alleles: additive (uppercase letter) and nonadditive (lowercase letter).

How many phenotypic classes would you expect?

The shortest plants are 130 cm. The tallest plants are 220 cm. Estimate how many centimeters each allele contributes to the height difference.

The genotypes are known for two bean plants. Plant 1 is genotype AABbccDdEE. Plant 2 is genotype aaBBCcDdEE. What are their heights?

If the two plants from above are crossed, what is the probability they will produce a plant that is taller than either parent?

In response to shortened day length and cool temperatures in the fall, many trees begin a period of senescence when the breakdown of chlorophyll exceeds chlorophyll production. The leaves of these trees appear to change to yellow and orange. Using your knowledge of photosynthetic pigments, explain the source of these yellow-orange hues.

Distinguish between the structure of a prokaryotic cell and that of a eukaryotic cell.

9. You are studying cuttlefish and you observe that females mate primarily with larger males. You suspect that sexual selection may be influencing male size.

9a. Place a check (√) next to the pieces of information provided by your existing observations and place an X next to missing information you still need to be certain sexual selection is operating:

____Trait variation in males

____Trait variation in females

____Fitness differences in males

____Fitness differences in females

____Variation in the male trait confers a fitness benefit

____Variation in the female trait confers a fitness benefit

____Genetic basis for the male trait

____Genetic basis for the female trait

9b. Females may be choosing larger males because large size is a proxy for high __________________
