Answer:
In classic research, Dweck (1975) found that boys tend to attribute their poor performance in math to unstable internal factors, whereas girls tend to attribute their poor performance in math to stable internal factors.
Explanation:
Here, we are talking about motives related to attribution. Notice that Dweck found that boys attribute their success in math to unstable internal factors, and girls to stable internal factors.
External and internal are related to the locus of the attribution, the "location" of the cause of success or failure. For instance, an external attribution may be the fact that the test was easy. An internal one may be our own ability in math.
Unstable and stable are related to the stability of the attribution. For instance, cramming for the exam is an unstable attribution, since the effort we put into studying may vary each time. Ability, on the other hand, is a stable one, since it lasts and has consistency.

Explanation:
Concordance: This is a term used in genetics. This term is used to imply the presence of the same trait/characteristic in both the members of a pair of twins.
Twins can be of 2 types. They are monozygotic twins and Dizygotic twins.Monozygotic twins are identical twins, i.e. they are formed from one zygote that later splits into two forming two embryos.
Dizygotic twins are non-identical twins or fraternal twins formed from the fertilization of two different eggs with two different sperm cells.
Concordance values can be calculated as:
C = Number of concordance pairs/(number of concordant pairs + number of discordant pairs)
Monozygotic twins generally have a concordance value of 44% for a specific trait.
Dizygotic twins have a concordance value of less than 5 % for a trait.
For identical twins the number of concordant pairs would be 50 out of 100.concordant pair would be
For non-identical twins, the number of concordant pair would be 17 out of 100.
For a recessive trait to be expressed, both the parents should be heterozygous for that trait.
