Answer:
The correct answer would be 2 in 4.
According to the question Xo and XO show codominance and express themselves completely when present in heterozygous condition. Cats bearing XoXO show patchwork of black and orange fur and are called tortoiseshell cats.
Xo codes for orange color fur and XO codes for black color fur. In addition, Y chromosome does not contain any gene associated with fur color.
Now, genotype of mother cat is XOXO (orange fur). So, the gametes formed would be XO only.
The genotype of father cat is XoY(black fur). So, the gametes would be Xo and Y.
The cross would lead to the formation of two male cats each having XOY as their genotype and two female cats each with XOXo as their genotype.
Hence, both the male cats would show orange fur and both the female cats would show patchwork of orange and black fur.
Therefore, we can conclude that 2 out of 4 would exhibit tortoiseshell coloring.
This is an example of microevolution.
Microevolution represents a small change in the genetic structure of the population. These changes manifest through the change in the allele frequencies of genes like in the case of dung beetles.
The causes of microevolution are evolutionary mechanisms, natural selection, genetic drift, mutations and gene flow.
I think the answer is B
Beacuse It follows the successful completion of S phase, during which the cell's DNA is replicated. Mitosis is a part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.
By examining the tree bark and recording it’s properties. I would note if the cells move and duplicate, I would also note any living organisms which lay on the surface
Answer:
Hello YOU!
Explanation:
Phrenology was a science of character divination, faculty psychology, theory of brain and what the 19th-century phrenologists called "the only true science of mind."Phrenology came from the theories of the idiosyncratic Viennese physician Franz Joseph Gall (1758-1828).
Gall believed that the bumps and uneven geography of the human skull were caused by pressure exerted from the brainunderneath. He divided the brain into sections that corresponded to certain behaviors and traits that he called fundamental faculties. This is referred to as localization of function.
Phrenology is considered pseudoscience today, but it was actually a vast improvement over that era's prevailing views of personality. ... But phrenology may be undergoing a redemption of sorts. Not the skull part—that's still considered bunk.
Phrenology was particularly popular in the U.S. because it fit so well with the idea of the American dream–the notion that we can accomplish our goals despite a humble heritage. Spurzheim believed that the brain was like a muscle that could be exercised.
