Answer:
Explanation:
Lets Tan seed be TT
Red seed be tt
A cross between TT ×tt will produce 4 Tt
TT× tt
!
F1 Tt Tt Tt Tt
a. Tan seed is dominant with an allele TT. It effect dominate that of red seed indicating it is a dominant traits while red seed is a recessive traits.
A dominant trait is a traits that is expressed in the phenotype of an organism the F1 generation are all Tan seeds this shows that the trait is dominant.
The genotype of the F1 melon is Tt in a dominant form
The F2 result follows the mendelian principle where segregation occur leading to a phenotypic ratio of 3:1
72Tan seeds:24red seeds
Where the 72 tan seed has the highest ratio and 24 red seeds has the smaller ratio.
Tt ×Tt
!
F2 TT Tt Tt tt
Phenotypic ratio 3:1
Answer:
sufficient root system that can support the plant's growth
The changes in foot structure in a bird population over. Evolution leads to less complex organisms. And also the lock-and-key model.
The evolutionary advantage that offered the creation of plant flowers was to attract organisms to help pollinate. It also helps to produce genetically variable seeds.
The flowers of angiosperms are specialized plant organs that attract organisms (e.g., bees) in order to help pollinate.
In angiosperms, these specialized organs (flowers) help to the pollination and thus create seeds to be spread across large land areas.
Pollination help to increase biodiversity by crossing different plants, i.e., by using the pollen from a given plant to pollinate others, thereby increasing genetic diversity.
