What is an allele

a form of a gene apex

This Punnett square sHow is the results of a cross between a tall pea plant and a short pea plant If tall is the dominant form of the trait what is the genotype of the tall pea plant

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.

Why do more people have attached rather than unattached earlobes

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

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.

Why did Mendel use purebread pea plants

To validate the results of his experiment.

A mother has one allele for color blindness and one Allele or normal vision what is the probability that her Gamete Will have the Allele for the color blindness

50%

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
