So the cells can react to the changes, and so that specialized cells can perform certain functions
Answer:
heterozygous purple pea plant and heterozygous purple pea plant
Explanation:
Suppose the gene controlling flower colour in pea is P. Allele P is dominant over allele p. So, PP and Pp produce purple flowers and pp produces white flowers. If two heterozygous purple pea plants (Pp) are crossed :
Pp X Pp :
P p
P PP Pp
p Pp pp
As evident, the progeny will have genotypic ratio of 1 : 2 : 1 ( PP : Pp : pp ) and phenotypic ratio of 3 : 1 ( Purple : white )
Hence two heterozygous purple pea plants will produce 3:1 ratio of purple to white pea plants.
For the answer to the question above asking what<span> differences would you expect to see in a population made up of individuals whose chromosomes experience crossing-over frequently compared with a population made up of individuals whose chromosomes do not cross over? My answer is that </span>I'd expect a larger gene pool and more diversity in the population whose chromosomes frequently cross-over or m<span>uch more genetic variability. </span>
<span>for example different phenotypes are most likely exhibited.</span>
Hello. Unfortunately your question is incomplete, which makes it impossible for it to be answered. However, through the context, we can see that your question is asking you to describe the cellular structures that you can see through a microscope.
To answer this question, you will need to look at biological material under a microscope to see what cells this material has and the structures it has. To do this, you will need to determine what material you will be using. This material can be a leaf, flower, a piece of fruit, or any other material that contains cells. After choosing the material, you need to search for a protocol, a tutorial, that shows how this material can be prepared so that the cells can be visualized through a microscope. This protocol can be found on the internet and in articles. You must follow the entire protocol to the letter, to be able to identify the cellular structures.
