In meiosis, the chromosome or chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.
Answer:
Natural selection will select the type of ostriches that can run up to 40 mph.
Explanation:
According to the theory of natural selection, organisms with favorable traits following their environment are more likely to reproduce. In doing so, they pass on the better traits to their next generation for the survival of their species.
This process allows organisms to adapt to their environment. And the survival of species is assured.
Here, the type of ostriches that run slow probably fall prey to the jackals. To maintain survival, the ostriches reproduce and lay eggs. If out of almost a dozen eggs, one or two are left to hatch than the <em><u>chances of their survival</u></em> will greatly be affected if the hatching ostriches are of the <em>slow-running type</em>.
Therefore, natural selection may stay in favor of <em>fast-running ostriches</em> to hatch.

Answer:
Farmers have been using selective breeding for improving their crop qualities and producing animals with better characteristics.
improved so that mankind can benefit from it.
Selective breeding is not okay on a bigger level where it might eradicate the natural varieties of plants and animals completely. When done on a larger level, the wild-type traits of plants and animals will change and be removed completely. This will lead to lesser genetic diversity.
