Answer:
A. homologous structures
Explanation:
The answer is homologous structures.
A male cat and a male dog both have masculine penile <em>structures. </em>
They are are two different organisms, but the two penises are in a similar form because they are both penises.
Same Structures = Homo Structures
Same with any other parts
Answer and Explanation:
cross: BbTt x bbTt
<u>Cross for B gene</u>
Parental ) Bb x bb
Gametes) B b b b
Punnet square) B b
b Bb bb
b Bb bb
F1) Genotypic proportion: 2/4=1/2 Bb : 2/4=1/2 bb
Genotypic ratio 1:1
Phenotypic proportion: 2/4=1/2 B- : 2/4=1/2 bb
Phenotypic ratio 1:1
<u>Cross for T gene</u>
Parental ) Tt x Tt
Gametes) T t T t
Punnet square) T t
T TT Tt
t Tt tt
F1) Genotypic proportion 1/4 TT
2/4 Tt
1/4 tt
Genotypic ratio 1 : 2 : 1
Phenotypic proportion: 3/4 T-
1/4 tt
Phenotypic ratio 3 : 1
Answer:
In mammals, oxygen is carried through the red blood cells called hemoglobin. The reason is that the oxygen is very important for the cell for releasing energy. This energy is used by the cell in different processes.
2) These adaptations are adapted by the organisms in order to perform different functions. In slow twitch skeletal muscles having high number of mitochondria because it requires more energy while fast twitch skeletal muscles contains less amount of mitochondria due to low requirements of energy. These characteristics are adapted according to the performance of the body parts.
Answer:
12 : 3 : 1
white : yellow : green
Explanation:
Given that genes A and B control the fruit colour in following ways:
A_B_ or A_bb = white
aaB_ = yellow
aabb = green
The genes undergo independent assortment so:
AaBb X AaBb =
A_B_ : A_bb : aaB_ : aabb
9 : 3 : 3 : 1
white : white : yellow: green
12 : 3 : 1
Hence, ratio of white : yellow : green is 12: 3: 1
