Answer:
Duplication of Hox genes made increased morphological complexity possible.
Explanation:
- The hox gene cluster consists of a group of related genes that function to controls the basic body plan of an embryo and also define the head to the tail axis.
- These are mainly responsible for ensuring the correct position of al the structures in the body.
- Since the anterior-posterior axis all the vertebrates are established by these hox genes this points out to the fact that common information is needed amongst all he vertebrates to define the various morphological variations that occurred.
- The hox genes have shown duplication in the course of evolution and they have undergone a four-fold duplication which has led to the generation fo different structures in the various organism and is thus responsible for the increased morphological complexity.

Answer with Explanation:
The large sample size allowed Gregor Mendel to make comparisons quantitatively. The <em>"margin of error"</em> is narrower and it allowed him to<em><u> detect statistically significant results</u></em> through its statistical power.<em> Large sample sizes have a greater statistical power.</em> However, it takes a lot of t<em>ime, effort and money.</em> Mendel was very persistent and had the driving force. This allowed him to develop the<em> "Three Principles of Inheritance." </em>
A smaller sample size doesn't give a significant difference because the samples are quite random. This has a<em> tendency to mask the result.</em>

What is a bacterial chromosome called?
Bacterial chromosome is called nucleoid. It is an irregularly shaped and contains genetic material. It is also called as genophore.
What is meant by eukaryotic chromosome?
- Eukaryotic chromosomes are found in the cell's nucleus.
- The DNA inside the nucleus is organized into chromosomes. At the most basic level, a chromosome is a molecule of DNA that is tightly coiled around proteins called histones.
What is the difference between bacterial and human chromosome?
- Bacterial chromosomes are circular in contrast to human chromosomes, which are linear.
- Furthermore, bacterial circular chromosomes are found in the nucleoid area rather than the nucleus, an organelle that is membrane-bound.

A) no. the man can’t be a carrier
b) his father
c) no. the colorblindness has to show up on both X and Y chromosomes to be colorblind. So if the mother is not colorblind nor a carrier, then most likely it won’t happen since it’s a recessive gene.
