Dad: TtBb
Mom: ttbb
You have to use distribution for dihybrid crosses. Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait. So for example with Dad, I will number the traits:
T(1)t(2)B(3)b(4)
To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb. Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.
Cross:
tb
TB TtBb
Tb Ttbb
tB ttBb
tb ttbb
The phenotypic ratio is 1 Tall Brown: 1 Tall Blue: 1 Short Brown: 1 Short Blue
Mutation is the source of differences in the dna code.
What is Mutation?
- A mutation is a permanent change in the DNA sequence of an organism.Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
- Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
- Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.

Answer:
The design of an experiment is synergistically related to the method of difference. Both are required in order to test a hypothesis and deliver a conclusion or evidence.
Explanation:
im not totally sure but hope it helps
Answer:
The student is wrong, just because the analogous structures of any two organism may have the same structure or even have the some relation between there way of operation or functions.
Explanation:
- <u>Analogous Structures:</u>
As the similarity between two or more different organisms structure or any organ does not means that they have same ancestors or have the common origin from which the evolve into two different species. Now analogous structures are very much similar in there structure physically, but two different organisms may use them for the same function, which is astonishing to see or observe in way different species.
As the structure of the flipper of a Dolphin has similarity with the phalanges of a human being and with the wings of the bat. As all of them functions for the basic need of movement or locomotion from one point to another. While, all the three species are very much different in there features and are not the same obviously.

Answer:
Plants, however, are rooted in place and must respond to the surrounding environmental factors. Plants have sophisticated systems to detect and respond to light, gravity, temperature, and physical touch.
