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:
variables
Explanation:
Studying one trait at a time ensures that multiple variables are not changing simultaneously.
Answer:
Do plants undergo photosynthesis, cellular respiration or both? plants undergoes both photosynthesis and cellular respiration
Explanation:
Plants are autotrophs i.e they produce food for themselves through a process called photosynthesis. Cellular respiration occurs both in plants and animals, it allows the conversion of adenosine diphosphate (ADP) into adenosine triphosphate (ATP). Plants needs energy which calls for it to undergo a chemical reaction called cellular respiration
