Question

i need help, i have a final tomorrow and I don't know gregors laws of heredity, can anyone help explain them?

Answer 1

There are three laws of Inheritance. They are as follows:

1. The Law of Dominance: In a cross between contrasting homozygous individuals, only one form of the trait will appear in the F1 generation - this trait is the dominant trait.
2. The Law of Segregation: during the formation of gametes, alleles responsible for a trait separate; this allows for recombination during fertilization.
3. The Law of Independent Assortment: alleles responsible for different traits are distributed to gametes (and thus the offspring) independently of each other.

Hope this helps in some way.

Answer 2

ok, whats a allele

Answer 3

Answer 4

ok

Answer 5

Allele: one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

Answer 6

ok explain autosomes?

Answer 7

Easier to understand version of an allele: any of several forms of a gene, usually arising through mutation, that are responsible for hereditary variation.

An autosome is any chromosome that is not a sex chromosome.

Answer 8

ok, whats incomplete dominance

Answer 9

Incomplete dominance refers to a genetic situation in which one allele does not completely dominate another allele, and therefore results in a new phenotype. Examples are on this website that might help you understand more: http://examples.yourdictionary.com/examples-of-incomplete-dominance.html
