Is eye Colour an example of continuous variation?

Is eye Colour an example of continuous variation?

Which are examples of discontinuous variation? Discontinuous: Eye colour, handedness & lobed/lobeless ears. Continuous: Hand span, arm length & height.

Is Skin Colour continuous variation?

And clearly hair color, skin color and eye color all fall under the definition of a continuous trait, because even though they dont seem to be affected by the environment, they are definitely polygenic traits and show a gradation, so they’re definitely continuous traits.

Is height a continuous trait?

Continuous traits are common in humans, who show a wide range of possibilities in characteristics such as height, skin color, learning ability and blood pressure. These traits are frequently seen in agriculture, as well.

What is variation example?

The individual members of a species also have differences in characteristics. For example, humans have different coloured eyes, and dogs have different length tails. This means that no two members of a species are identical. The differences between the individuals in a species is called variation.

Do humans have variations?

In fact, research results consistently demonstrate that about 85 percent of all human genetic variation exists within human populations, whereas about only 15 percent of variation exists between populations (Figure 4). That is, research reveals that Homo sapiens is one continuously variable, interbreeding species.

Are Momo twins rare?

Monoamniotic twins are rare, with an occurrence of 1 in 35,000 to 1 in 60,000 pregnancies.

How do Momo twins happen?

Monoamniotic twins occur when a single fertilized ovum (egg) results in identical twins that share a common placenta and amniotic sac. Monoamniotic twins are very uncommon, representing approximately one percent of identical twins and less than 0.1 percent of all pregnancies.

How common are MoDi twins?

Monochorionic twins generally have two amniotic sacs (called Monochorionic-Diamniotic “MoDi”), which occurs in 60–70% of the pregnancies with monozygotic twins, and in 0.3% of all pregnancies.

How common are mo di twins?

Monochorionic, diamniotic (MCDA) twins are the product of a single fertilized ovum (egg), resulting in genetically identical offspring. MCDA twins share a single placenta (blood supply) but have separate amniotic sacs. The occurrence of MCDA twins occurs at a rate of three to four in 1,000 live births.
