The angle bisector theorem is commonly used when the angle bisectors and side lengths are known. It can be used in a calculation or in a proof. An immediate consequence of the theorem is that the angle bisector of the vertex angle of an isosceles triangle will also bisect the opposite side.

One language used for scientific naming

Latin I think. It's like nomenclature, or something like that. ☺

A male is heterozygous for the trait that produces freckles on the skin, and he has freckles. if he marries a woman who is also

kakasveta [241]

F- allele for freckles
f- allele without freckles

1) The man is heterozygote and has freckles, its indicating that the allele for freckles is dominant.
A cross between him and a woman who is also heterozygote: Ff x Ff
it would result in the following probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - heterozygote with freckles: Ff
- 1/4- homozygote without freckles:ff

Their son would have a probability of 75% of being born with freckles.

2) The cross resulted in this probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - heterozygote with freckles: Ff
- 1/4- homozygote without freckles:ff
So, the chance of being born heterozygote for this gene is 2/4, which is the same as half (50%).
