Answer:

Similarity of structures due to common ancestry is called homology.

Explanation:

Homology is the relationship that exists between two different organic parts when their genetic determinants have the same evolutionary origin or a common ancestry, that is, it is a feature or characteristic that is shared by all descendants of a common ancestor, and not shared with other groups. For example, the arrangement and structure of limbs in vertebrates are similar, these similarities then come from a common ancestor to all vertebrates.

STatiana [176]

Answer:

b) True.

c) False.

d) True.

e) False.

f) True

g) True.

Explanation:

a) The main characteristic of homologous chromosomes is that they have an equal size. There is a difference in size on both chromosomes.

b) In number one, two chromosomes are homologous. In number two also two chromosomes are homologous. On the other hand, the chromosomes at number one and two are different. Each chromosome has two sister chromatids.

c) A DNA molecule has a double helix, that is, two chains. When a DNA chain is broken and a chromatide has a DNA chain, then two chromatids make up a chromosome and a DNA chain, in this way there are eight dsDNA molecules

d) If each chromosome contains a centromere, therefore, there are four centromeres on all four chromosomes.

e) If a chromosome contains four telomeres, therefore there will be sixteen telomeres.

f) The function of cohesin is to regulate the separation of chromatids in the cell division process. When DNA replication is complete, the DNA compacts and condenses to form mitotic chromosomes.

g) The CENPA protein is encoded by the CENPA gene.
