Variations of Mendelin Inheritance.

Question 1

What are homozygous traits?

Answer 1

The same

Question 2

What are heterozygous traits?

Answer 2

Different

Question 2

Describe genotype vs. phenotype

Answer 2

Genotypes are the letters (Rw, RW, RR, etc) and location for the alleles. The phenotype is the expressed trait from the alleles.

Question 3

Explain codominance

Answer 3

Codominance is when both alleles are expressed in the trait. They are both present equally in the trait. This is when both traits are dominant (ex: RW).

Question 4

Explain incomplete dominance

Answer 4

Incomplete dominance is when one trait cannot completely mask or dominate the other. This is when the white flower and red flower becomes pink. They blend together and show both.This uses this same letters as typical dominance (Rw)

Question 5

What is a lethal allele?

Answer 5

alleles that cause the death of certain alleles.

Question 6

What are polygenic traits?

Answer 6

inheritance of a trait governed by more than one gene.

Question 7

what is an allele

Answer 7

a gene variant

Question 8

document

Answer 8

only one allele needs to be there to have the expressed trait.

Question 9

recessive

Answer 9

two alleles have to be there to have the expressed trait

Question 10

hemizygous

Answer 10

this means you only have one copy of the allele. (sex trait stuff)

Question 11

Name all of the blood types with their genotype

Answer 11

AO, AA,

Question 12

sex linked traits

Answer 12

An allele on the sex chromosome (color blindness)

Question 13

sex limited traits

Answer 13

Sex limited are genes that occur in both sexes on the autosomes but are expressed only in the gender

Question 14

An example of an X-linked sex influenced trait

Answer 14

color blindnes

Question 15

why are lethal alleles recessive?

Answer 15

because you need a pair of identical alleles that are both present in an organism that ultimately results in death of that organism
