In alley cats, the coat color is determined by a gene carried on the X chromosome. At the same time, the alleles are expressed as intermediate (nondominance) inheritance. Genotypes and colors are as follows: Females: XXb = yellow Males: XbY = yellow %3D XBXB calico XBY = black XBXB black 17. A calico cat has a litter of eight kittens: one yellow male, two black males, two yellow females, and three calico females. What is the color of the father of the litter? 18. A black cat has a litter of seven kittens: three black males, one black female, and three calico females. Comment on the probable paternity of this litter and explain. A yellow cat has a litter of four kittens: one yellow, and three calicos. Assuming a single father for the litter, what is the sex of the yellow kitten? 19.

Communication

Communication is a method of transferring information between two persons or organisms. Communication is possible using mutually understood behaviors such as signs, symbols, or language. In the year 1980, S. F. Scudder proposed communication theory. According to his ideas, all living beings on the earth communicate, but the methods of communication differ. Communication skills are now part of soft skills.
