The first cloned cat, carbon copy (cc), was tabby, while the cat she was cloned from, rainbow, was calico. the surrogate mother was a tabby. select the explanation that best explains why cc would never have been identical in pattern to rainbow.

Answer: During embryogenesis, one X chromosome is randomly inactivated in each cell lineage.

This phenomenon called X-inactivation occurs in some female mammals. Furthermore, this proves that although two clones are genetically identical, they may not look the same. There are other environmental factors that may affect the activation or suppression of a gene.

While still a debated subject, phenotype (such as hair color) is the result of gene-environment interactions.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.

can i get the brainliest pls

explanation:

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
