Arm and hand movements start in the brain, in an area called the motor cortex, which sends a signal to the spinal cord that's translated into a motion. The researchers found that while the fetus is growing in the womb, up until about 15 weeks, the motor cortex and the spinal cord are not yet connected, but right- or left-handedness has already been determined.

Answer:
Explanation:
The genetic determination of coat colors in calico cats is linked to the X chromosome wherein calicos are nearly always female, with one coat color allele linked to the maternal X chromosome and a second coat color allele linked to the paternal X chromosome.
Since, the females possess two X chromosomes (XX), they can be either homozygous for each coat colour or be heterozygote (calico). But in the males, since this trait is X- linked and males have just the one X chromosome (XY), they can only possess either of the coat colour and not be an heterozygote. But an XXY male cat can be a calico due to the presence of the two X chromosomes.
