1) all the possible genotypes are also identified by color in the image below :AABBAAbB or AABbaABB or AaBBaAbB or aABb or AabB or AaBbAAbb
aAbb or AabbaaBB
aabB or aaBbaabbThere are 9 different genotypes in total. These can be achived by mixing the alleles of both genes of each parent (just like it's represented in the square).
2) there are 4 phenotypes
-one with an allele A and allele B that would dominate the other. (AABB, aAbB, for example)
- one with all alleles recessive- aabb
-one with the recessive alleles in the gene A but heterozygotic/homozigotic dominant for gene B ( for example: aaBB)
-one with the recessive alleles in the gene B but heterozygotic/homozigotic dominant for gene A ( for example: Aabb)
3) <span>probability of having offspring with the aabb genotype: 1/16
Just by looking at the punnet square, you can see that only one has the aabb genotype, in all the 16 possibilities.

Your answer would most likely be (c) or the third answer given.
The coleoptiles which tips were removed will be short and straight while coleoptiles which were cut with the tips separated by mica will be short and straight. Ceoptiles which were cut tips and separated by agar they will be tall and straight.
The set of coleoptiles which will be left in the darkness for 24 hours will be tall and bent. While the set which is in the direction of light for 24 hours will be tall and bent.
Observation is that coleoptile will grow straight if the chemical was evenly distributed and curved away from block side as if growing towards the light because dark side has the higher concentration of auxin.
Answer:
The Paleozoic involved the appearance of fish, and eventually of life moving onto land. The Mesozoic was dominated by dinosaurs. The Cenozoic started with the extinction of the dinosaurs, and included the development of birds and mammals. ... The Mesozoic Era ended with another extinction.
