Answer:
Alternation of generations in plants permits both mitosis and meiosis but at different stages.
The zygote will undergo many rounds of <u>mitosis</u> and give rise to a diploid multicellular plant called a sporophyte. Specialized cells of the sporophyte will undergo <u>meiosis</u> and produce haploid spores.

Answer:
Green peas if it does not have a dominant allele for yellow peas.
Explanation:
In pea plants, yellow is the dominant allele color of peas and green is the recessive allele color of the pea. So the genotype that makes yellow color pea is YY or Yy and the genotype that is responsible for producing green color pea is only YY.
This shows that homozygous dominant or heterozygous dominant condition gives rise to yellow color pea and only homozygous recessive condition would give rise to green color pea plants.
Therefore if a pea plant has the recessive allele for green peas it will produce green peas if it does not have a dominant allele for yellow peas.
<u>Answer:</u>
An example situation of artificial selection is "More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory".
<u>Explanation:</u>
- The process of breeding animals to acquire the desired characteristics by the external means other than natural selection and behavior of animal itself is called as artificial selection.
- The first artificial selection was carried out by Darwin when he mated penguins that would have a higher chance of breeding.
- The practice of artificial selection was existing in human civilization a long time ago.
- This process was used to use wild animals and domestic animals in battles and other household works.
