Answer: "sexual dimorphism" .

Answer - Codominance
Reasoning - Codomance since the black cat and tan cat is combined when it was breed in turn making its both able to co-dominance together. Rather having a black cat only as a dominance or tan cat.
The name of the group that consists only of modern humans and their direct ancestors is known as Hominidae. It is also called by the name of Hominids or great apes. Originally the term Hominidae referred to only the humans and their closest relatives. There are still people that continue to use this term in its restricted sense, rather than the modern sense.<span />
The first geneticist has identified an obese allele that he or she believes to be recessive. We will define his or her allele as o1 and the normal allele as O1. The obese allele appears to be recessive based on the series of crosses he or she performed.
Cross 1 with possible genotype:
Obese (o1o1) × Normal (O1O1) F1 All normal (O1o1)
Cross 2 with possible genotypes:
F1 normal (Oo1) × F1 normal (O1o1) F2 8 normal (O1O1 and O1o1)
2 obese (o1o1)
Cross 3 with possible genotypes:
Obese (o1o1) × Obese (o1o1) All Obese (o1o1)
A second geneticist also finds an obese mouse in her colony and performs the same types of crosses, which indicate to her that the obese allele is recessive. We will define her obese allele as o2 and the normal allele as O2.
The cross of obese mice between the two different laboratories produced only normal mice. These different alleles are both recessive. However, they are located at different gene loci. Essentially, the obese mice from the different labs have separate obesity genes that are independent of one another.
The likely genotypes of the obese mice are as follows:
Obese mouse 1 (o1o1O2O2) × Obese mouse 2 (O1O1o2o2)
F1 All normal (O1o1O2o2)
