How do these effects on the gene pools lead to speciation

Biology
1 answer:

7 0

Answer:

Over time, genetic changes add up in each population.

These changes may prevent individuals from each population from being able to mate successfully with each other. If this happens, the two populations are considered to be distinct species.

Answer:

Engine is very much similar to the muscular system in a car.

Explanation:

The system is made up of the tissues which work with skeltal system to control the movement  of the body is called Muscular System. In a car the engine is very much similar to the muscular system. They both help their systems to move. Without them the car or body would not going to operate.Like the human body car parts are also specialised & perform specific tasks, but they all depend on each other.Many would compare the engine of the car with heart of human body.The heart is the engine of the body just like the car. Our brain is very much similar to the the car's computer system or CPU.Every car  is powered by an engine and most cars use an internal combustion engine which runs on gasoline.A car's overall power is a function of the size of engine as well as the factors such as timing of combustion and the type of transmission used.

Which of the following is true about offspring resulting from a cross that yielded TT, Tt, TT, ans Tt?
Vera_Pavlovna [14]

Additional detail found elsewhere: (T = Tall and t = short)

Answer:

All are expected to be tall

Explanation:

We are told that the T allele produces the tall trait, and the t allele produces the short trait.

Because the tall allele is denoted by an uppercase letter, it means it is the dominant allele, meaning if it is present even in one copy, the trait will be expressed. This is in contrast to the recessive short allele, 2 copies are needed for the trait to be expressed.

Individuals have 2 copies of every gene. Offspring that are TT, Tt, TT, and Tt all have at least one copy of the T (tall allele). Because this is the dominant allele, that means all of these offspring would be expected to be tall.
