Question

I am somewhat new to this site although I am a member, so I havethese questions I have answerd most of them my self yet I wouldlike to see if any experts, or people with some knowledge couldcould go ahead and do them so i can see if I am correct or not. Idont actually expect anybody to be able to make a punnet square, asI myself had to make my punnet squares on paper. But these are thequestions below, I will put my answers the ones I have gotten in () but if you are either able to tell me if im correct or if notshow me some sort of steps to becoming correct? Thanks ZackCross.

Solve all of these problems using a Punnett Square. ( I Havedone this mostly on paper)

In certain bacteria, an oval shape (A) is dominant over round(a) and thick cell walls (B) are dominant over thin (b). A bacteriaheterozygous for both oval shape and a thick cellwall was crossed with a round bacteria with a thin cell wall.Describe the phenotype of the offspring.

(My answer not sure if correct but I got : Oval Thick wall: Oval Thin wall : Round thick wall: Round thin wall

1:1:1:1)

2. The ability to roll the tongue sideways (A) is dominant overthe inability to roll one's tongue (a). In humans, non-attachedearlobes (B) are dominant over attached earlobes (b). Two parentswith attached earlobes can roll their tongues. They are bothheterozygous for the tongue rolling trait.

1. What is the genotype of the mother? ( I got Bb Aa)
2. What is the genotype of the father? ( I got Bb Aa)
3. What are the possible gametes from the mother? ( I gotBA Ba Ab ab)
4. What are the possible gametes from the father? ( I got BA Ba Abab)
5. Draw the Punnett square, and combine the gametes to produceoffspring( I did on paper)
6. What is the phenotypic ratio of these offspring? (Didn'tunderstand?)

1. A man heterozygous for non-attached earlobes can roll histongue. A woman with attached earlobes can roll her tongue. Assumeboth are heterozygous for the tongue-rolling trait.
   1. What is the genotype of the mother?
   2. What is the genotype of the father?
   3. What are the possible gametes from the mother?
   4. What are the possible gametes from the father?
   5. Draw the Punnett square, and combine the gametes to produceoffspring
   6. What is the phenotypic ratio of these offspring?
      
      
2. In summer squash, white fruit color (W) is dominant over yellowfruit color (w) and disk-shaped fruit (D) is dominant oversphere-shaped fruit (d). If a squash plant purebreeding for whiteand purebreeding for disk-shaped fruit is crossed with a plantpurebreeding for yellow, sphere-shaped fruit, what will thephenotypic and genotypic ratios be for:
   1. the F₁ generation?
   2. the F₂ generation?

Any Help would be greatly apretiated I don't understand how thepoint system works but I did purchase the membership package thingso I do believe I will be able to award someone with these karmapoints which I purchased.
