I need help with this Feel free to only do 1 or 2 questions

9. D (100%)

10. C (Round and Wrinkled)

11. C (75%)

12. B (25%)

Explanation:

9. 100% will be brown, because brown (B) is dominant. That means that if all squares have Bb or BB once you fil out the punnett square, then the offspring would have to show the dominant trait. In this example, all possibilities for the organism were Bb, so brown.

10. Rr and rr are being crossed in this example. Heterozygous is Rr, Wrinkled is rr and Round is RR or Rr. The answer id Round and Wrinkled because one parent is Rr (round) and the other is rr (wrinkled).

11. Yellow seeds are dominant, so any box that has at least one Y will be dominant. 3 of the 4 boxed have a Y, therefore there is a 75% chance the offspring will be yellow.

12. Long hair is not the dominant trait, it is recessive. This means any box WITHOUT a capital S will be recessive. There will be one box, the lower left box. It will be ss. Since one out of four are ss, that means there is a 25% chance the guinea pig will have long hair.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.

its probably to later but whats the question
