Answer:
TT * Tt
Tt, Tt, TT, TT
Explanation:
Given -
Patrick is homozygous for tall head
Patricia is heterozygous for her tall head
The little baby Patty has a short head
Let us assume that the traits for short head is represented by "T" and trait for tall head is represented by "t"
Genotype of Patrick is "TT"
and genotype of Patricia is "Tt"
On crossing Patrick and Patricia, following offspring are produced -
TT * Tt
Tt, Tt, TT, TT
Out of four two are heterozygous tall headed and two are homozygous short headed.

Answer:
Due to early flowering in the mustard plant.
Explanation:
The scientists discovered that the flowering time of the field mustard had changed by observing more mustard plants which produces earlier flowers. The behaviour of the mustard plant change due to the change that occur in the environmental conditions that leads to early flowering in mustard plant. If this early flowering occurs for more generation, then the mustard plant will adopt this type of behaviour in normal environmental conditions that experience by the mustard plant.
