Genetics

the chromosomes are duplicated.

The crime scene investigators use the biotechnology and genetis technology for solving their case. They collect every sample from the crime scene and perform the laboratory tests on it which gives them clue about what would have happened on the crime scene and then DNA and the fingerprints are used to prove the identity of the person associated with crime scene

Using the Polymerase Chain Reaction, scientists can amplify even the smallest amount of DNA, by constant cycles of separation and replication.

a homozygous trait is when an offspring has either both dominant genes or both recessive genes from its parents. a heterozygous trait is when an offspring has both dominant and recessive genes. for example: a long-tailed cat is dominant and a short-tailed cat is recessive. the long-tailed cat (homozygous dominant) had offsprings with the short-tailed cat (homozygous recessive). by doing the punnett square, 100% of their offspring will be heterozygous.

what combination of sex chromosomes is shown in the image: XY (APEX)

Color blindness is a recessive sex linked trait.

Cause attached earlobes are the dominant trait. Unattached earlobes are reccessive.

The more samples you use, the closer your results will match probability.

Chloes best friend is Paige they are called the twinnies and they do everything together.:)
