Answer: genus, specific epithet.
Explanation:
The first part is the genus, it's always capitalized, while the second half is always in <em>italics </em>
e.g.<em> </em>Homo<em> sapiens </em>
Comparing DNA
Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor. Look at the diagram in Figure 9.3
Of what there are plenty of things that can be aged in many different ways
B and C are correct - A is incorrect as natural selection affects any generation of species. D is also incorrect as any species population change in an ecosystem inevitably affects another, even if it isn't a predator-prey relationship.
Q1. The answer is 53 chromosomes
Zebra has 44 diploid chromosomes (2n = 44). Zebra's gametes are haploid, so they will have 22 chromosomes (n = 22).
Donkey has 62 diploid chromosomes (2n = 62). Zebra's gametes are haploid, so they will have 31 chromosomes (n = 31).
After fusion of zebra's gamete (n = 22) and donkey's gamete (n = 31), the zonkey's zygote will have 22 + 31 = 53 chromosomes
Q2 and Q3. In the meiosis, the number of chromosomes is reduced by half. Since zonkey has 53 chromosomes, after meiosis it should have 53/2 chromosomes, which is not the whole number. This is the reason why they cannot produce normal gametes that will result, after the fusion, in the production of normal diploid zygote
