As you can see in the diagram presented below, the correct genotypes of the parents are TT and Tt.
Each parent give its children only one chromosome of the chromosome pair, therefore only one allele of the gene.
In our case, TT and Tt is the correct answer because one of the parents has to have the t allele to give to the Tt offspring.
But if both of the parents were Tt, one of the offspring would have tt genotype, and if the parents were TT and tt, all of the offspring would be Tt. Therefore, the TT x Tt combination is the only possible answer.

Answer:
<u>a) strong joints with restricted movement.</u>
Explanation:
Joints which are closely fitted cannot allow free movement because movement requires space in the joint so the bones can move in this space. So a closely fitted joint allow restricted or no movement at all. Weak joints with restricted movements are called weak because they are not well fitted closely. Strong joints with restricted movement is closely fitted, one of the example is joints of skull.
Because they are autorotrophs(they make their own food)so most organisms depend on them.
Answer:
No, If that was the case, then we should only be eating carbohydrates.
