Answer 2

Which do you think it is?

Answer 3

Epistasis : is a phenomenon that consists of the effect of one gene being dependent on the presence of one or more 'modifier genes' (genetic background). Similarly, epistatic mutations have different effects in combination than individually.

Recessive : relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents, i.e., when not masked by a dominant characteristic inherited from one parent.

Polygenic : trait is one whose phenotype is influenced by more than one gene. Traits that display a continuous distribution, such as height or skin color, are polygenic. The inheritance of polygenic traits does not show the phenotypic ratios characteristic of Mendelian inheritance, though each of the genes contributing to the trait is inherited as described by Gregor Mendel. Many polygenic traits are also influenced by the environment and are called multifactorial.

Codominance : is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.

Answer 4

i still dont know what it is? @pooja195

Answer 5

it may be polygenic but im not sure

Answer 6

ill give a medal just please help

Answer 7

It is Epistatic

Answer 8

example: widow's peak masked by the baldness gene.

Answer 9

sorry for responding too late.. :(

Answer 10

i got it thanks is there any way you can help me with this one At the end of meiosis I, chromosomes in the two resultant cells are duplicated but not homologous.

True
False

Answer 11

Answer 12

True

Answer 13

Wait no i think i'm wrong.

Answer 14

so false?

Answer 15

@nincompoop can you check the answer i just gave to someone? I'm unsure. Shouldn't they be homologous? Or ahh :/

Answer 16

* shouldn't they be ; meaning the chromosomes.

Answer 17

I would go with false @18jonea

Answer 18

ok thanks

Answer 19

@Destinymasha can you check to see if what i said was correct?
It's where i first mention @nincompoop
