The offspring that will be produced in the cross would have tortoiseshell fur.
<h3>X-linked traits</h3>
In cats, the male is XY while the female is XX.
Assuming that black fur is caused by the allele B and the orange fur is caused by A
A black female will have the genotype 
An orange male will have the genotype 
Crossing the two:
x 
Offspring:
,
,
, and 
= tortoiseshell fur female
= tortoiseshell fur male

Growth factors are hormones, proteins, or steroid molecules that regulate many cellular functions. They can stimulate the cell division by giving the signal to the cell to progress in the cell cycle.
<u>Explanation</u>:
Growth factors are naturally produced within the body and travels through the body to bind to their receptors present on their target cells. These growth factors are capable of signalling the cell to divide, proliferate, or heel. Their main aim is to signal or tell other cell when to do and what to do. Due to the binding with the receptors the growth factors activates specific genes.
