There is a 1:4 chance of getting JjQq. The parent JjQq can produce four genotypes: JQ, Jq, jQ, and jq. the parent JJQq can produce two genotypes: JQ and Jq. When we do a punnett square: 
JJQQ, JJQq, JjQQ, JjQq, 
JJQq, JJqq, JjQq, and Jjqq
There are two JjQq.

These chromosomes carry different variations of similar genes in them. In humans there are 46 chromosomes in total. These chromosomes are paired and form 23 homologous pairs. Among these 23 homologous pairs, 22 pairs are autosomes and one pair are the sex chromosomes which are either (XX or XY). The sex chromosomes determine the sex of an individual. XX chromosomes represent a female and XY chromosomes represent a male.

omeli [17]

Answer:

<u>A. red blood cells containing malaria</u>

Explanation:

Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite <em>Plasmodium sp.</em><em>,</em> which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.

When they multiply within the red blood cell, they <u>burst the red blood cell open</u>, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.

Malaria is a deadly illness, causing harm to its hosts, and in many cases death. <u>Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.</u>
