Vg: normal wings; vg: vestigial wings
Bt: normal wings, bt: bent wings
But to simplify, I write:
V: normal wing; v: vestigial wing
B: normal wings; b: bent wings
P: VvBb x VvBb
Gametes (both) VB, Vb, vB, vb
F1 (Punnett Square)
.....|.... VB...|...Vb...|...vB...|..vb
VB | VVBB | VVBb | VvBB | VvBb
Vb | VVBb .| VVbb | VvBb | Vvbb
vB | VvBB ..| VvBb | vvBB | vvBb
vb | VvBb ..| Vvbb. | vvBb | vvbb
Phenotypic ratio: 9/16 V-B- (normal) : 3/16 V-bb (bent) : 3/16 vvB- (vestigial) : 1/16 vvbb (vestigial-bent)
The answer is polygenic inheritance.
Polygenic inheritance is responsible for traits that are controlled by two or more genes. It is also called multiple gene inheritance. Examples of polygenic inheritance are height, weight, skin color, eye color.
Since a great number of genes control one trait, it is expected that each one has<span> a relatively small effect</span>
Controll group
Controll group i just had a test like this
Answer:
A
Explanation:
Reptiles arose about 310–320 million years ago during the Carboniferous period.
Answer:
a.)It will rise faster in cooler air
a.) heat
Explanation:
i
A hot air balloon rises faster if cold air were to surround it due to density differences between the air in the two medium.
- Hot air is less dense as the average kinetic energy of the molecules is greater.
- Cold air is denser.
- This density contrast causes the balloon to move up at a high pressure.
ii. Heat
The average kinetic energy of the molecules in a substance is termed heat.
Heat is a form of thermal energy measured by the kinetic energy possessed by molecules in a substance.
