Which describes the mating of organisms that have different homozygous alleles for a single trait? monohybrid cross dihybrid cross homozygous cross heterozygous cross

Answers

The term which describes the mating of organisms that have different homozogous alleles for a single trait is monohybrid cross. The 'mono' refers to the singular trait while 'hybrid' refers to the crossing of two different parents. Monohybrid cross yields offsprings that have one dominant and one recessive allele for that particular gene in question.

Monohybrid cross describes the mating of organisms that have different homozygous alleles for a single trait. Thus, the correct option is A.

What is Trait?

A trait may be defined as the phenotypic appearance or manifestation of the desired characters that are selected for the study.

A Monohybrid cross may be defined as a cross between parents that differed in a single characteristic. The F2 phenotypic ratio of the monohybrid cross is 3:1, while the F2 genotypic ratio is 1:2:1.

Therefore, it is well described above.

Is it possible for two parents that both have a recessive trait to pass off the dominant trait to their offspring???

Answers

To get a recessive trait, they have to receive one of each from each parent. So in this case, they would be getting one form each parent which would likely give an equal chance of getting either the dominant or recessive trait. Thanks my theory, but hope it helps?

Heat moves through liquid and circulates due to density

Answers

When heat moves through liquid and circulates to density, this process is called convection. This process opens the possibilities of hotter thus,less dense material to go up and the colder one, thus denser material, to go down under the influence of gravity which eventually results heat transfer.

This is called convection
