What is an allele

a form of a gene apex

What happens during interphase

the chromosomes are duplicated.

What is the difference between a homozygous trait and a heterozygous trait and can you please provide an example for each

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.

Is color blindness a dominant or a recessive trait

Color blindness is a recessive sex linked trait.

If an organism has five pairs of chromosomes how many different gametes could it produce without crossing over

Ill tell you when your older

Why do more people have attached rather than unattached earlobes

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

What is the role of microfilaments in cell division

They pull the cell membrane in.

They Split The Cell During Cytokinesis.

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.

What happens directly after prophase

Metaphase

In Mendel's experiment why did wrinkled seeds show up in the F2 generation even though they were not present in the F1 generation

Wrinkled seeds are recessive

The F1generation carried recessive alleles.

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

Why deos A mother has one allele for dimples and one allele for no dimples What is the probability that she produces a gamete with the allele for dimples

Answer is 50% :: Apex
