Identical twin look kinda the same. And they are basicly like the same person because they do the same thing. 
Fraternal twins do not have the same gender sometimes and they do not look alike. Also have different personalities. Also not really the same personality.

Hope I helped! :)

Identical twins are formed through the process of meiosis where a fertilised egg separates to form two identical cells with a common genetic information.
Fraternal twins on the other hand are developed from the fertilisation of two different eggs and two sperm cells. This type of twins possess unique genetic information.

Vinil7 [7]

Answer:

1.31 cM

Explanation:

Total offspring = 2205

Since two genes are involved, F1 progeny should have four types of combination. Out of them two are 17 and 12 which definitely means they are in lesser number. Since recombinants are always less than parental progeny in linkage, the given two types are recombinants.

Recombination frequency = (Number of recombinants / Total progeny) * 100

= [ ( 17 + 12 ) / 2205 ] * 100

= ( 29 / 2205 ) * 100

= 1.31 %

Map distance = Recombination frequency

Hence, distance between two genes = 1.31 cM

In-s [12.5K]

Answer:

True

Explanation:

The technique used by researchers to ask subjects to describe element of their experience is the introspection technique. The introspection involves the process by which an individual examines his own conscious emotions and thoughts by deeply looking inwards.

The introspection technique is similar to the methodology of Titchener. Titchener studied how the mind worked  and also the different components of consciousness; he made use of introspective techniques and analysis to determine this.
