How are mitosis and meiosis similar

they both produce new cells(apex)

they both have prophase and metaphase (anaphase)

They both involve duplicating chromosomes.

they both have simular steps.

What happens during interphase

the chromosomes are duplicated.

What is the purpose of a punnet square

rffvvfwe

What does polymerase chain reaction enable scientist to make

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

What happens during S phase

DNA is replicated.

Chromosomes are duplicated.
During S Phase, there is the occurrence of DNA replication.

The force that is used to separate DNA fragments on a gel in the process of electrophoresis is what

Gel Electrophoresis

What is the third step in making DNA fingerprints

The third step in making DNA fingerprints is to scan the fingerprint that you took in step two.

What is the purpose of a punnett square

A Punnett Square is a diagram used by biologists and geneticists to analyze crossbreeding, i.e. to determine the probability of the possible types of offspring which would result from crossing parents of similar or different genotypes and phenotypes. It is used to show every type of combination possible when one or more maternal and paternal alleles interact, for each gene being studied in the cross.

Though not always accurate, this diagram also generally teaches students that are studying genetics how receiving one allele from two different parents does not always have a straightforward outcome. It shows students that there are a large number of possibilities when paternal and maternal alleles interact, especially when one or more parent has an unknown allele.

The inheritance pattern of a trait controlled by two or more genes is what

A polygenic inheritance pattern.

Which is a reason cells divide

They divide so the can make NEW cells to replace the ones that died.

To reproduce

To replace damaged cells~

Why did Mendel study such a large sample of pea plants to determine the probability of inheritance

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

Are restriction enzymes and restriction endonucleases the same thing

No restriction endonucleases is one of the examples for restriction enzymes.

Why does sex linked traits follow different patterns of inheritance than other traits

Males and females have different sex chromosomes.

What best describes the the law of independent assortment

The factors for each trait are separated independently when sex cells form.

How are meiosis and mitosis different

mitosis only has to do with celluar reproduction

meiosis has to do with sex cells reproducing
Mitosis creates new cells that are used for development, repair, asexual reproduction and growth. Meiosis creates cells in order for organisms to reproduce sexually.

A plant can have green (G) or yellow (g) leaves. It can also have a long (K) or short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross of a plant with a genotype GGKk. What pos

Gk, gk

What is the probability that a father produces a gamete with the allele for attached earlobes if he has one allele for detached earlobes and one allele for attached earlobes

50%

Which best describes a gene

A piece of a chromosome. -Apex

Why can gel electrophoresis separate dna fragments

DNA fragments are negatively charged, :: Apex

A scientist uses material in her lab to separate dna fragments by size .what process is she using

Gel electrophoresis.
