3. In 1981, a stray black cat with unusual curled-back ears was adopted by a family in California. Suppose you were the person who owned the first "curl" cat, and wanted to develop it into its own breed. How would you determine whether the allele for curled ears is dominant or recessive? Why does it make a difference for breeders whether an allele for a trait is dominant or recessive?
It is possible to determine whether the allele for curled ears is dominant or recessive by performing a test cross. It is fundamental for breeders because desired traits show differential patterns of inheritance.
In a diploid (2n) organism, a given gene locus exhibit two different variants or forms called 'alleles'.
An individual is homo-zygous when both alleles for a given gene locus are the same, while an individual is heterozygous when alleles are different.
In cases of complete dominance, the expression of the recessive allele is completely masked in heterozygous individuals.
A breeder is a professional who performs genetic crosses between different organisms in order to obtain offspring (eg., plants, animals, etc) with desired phenotypic features.
A test cross is a type of cross that breeders use to determine whether an allele is dominant or recessive (in this case, the allele for curled ears).
In a test cross, the organism that is a carrier of the unidentified allele is crossed with another organism that is believed to be homo-zygous for the recessive trait, and then the proportion of offspring is examined.

How do limiting factors influence each other?
Answer:
In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. ... Other changes in limiting factors will cause a population to decrease.
Explanation:
hope it helps.
Answer: Two or more limiting factors may work in conjunction with one another.
Explanation: For example, parasites and disease. In this case, we have a biotic factor (parasites) combined with an abiotic factor (a disease-causing virus). Combining these limiting factors creates a deadly team that can have an even greater impact on a population's growth and survival.

Are there any differences between what we need as humans and what animals need? If so, what?
Answer:
Animal society is mainly based on instincts or reflex behavior, whereas human society is based on reason or rational behavior. There are no rights and duties in animal society. Every animal lives upon his physical powers whereas human society has a wonderful system of law and order.
Animals usually live in the wild where they have to find there own food and hunt for it, where we as humans spend money on our food and it is all at the grocery store. There are more differences but this is one main difference.
