Answer:
The correct answer is - 2 genes.
Explanation:
The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:
suppose there are only two gene - TT dominant over tt and CC dominant over cc
then the cross would be - RRCC - rrcc
gametes - RC and rc
Cross F1: RrCc
Self cross in F2:
offspring by Punnet cross are:
RRCC -->1/16
RRCc, RrCC .---> 4/16
RrCc, RRcc, rrCC--->6/16
rrCc, Rrcc--->4/16
rrcc ----> 1/16
thus, the correct answer is 2 genes

Answer:
The correct answer is: Fragile X Syndrome.
Explanation:
Fragile X Syndrome is a genetic condition that has an X-linked dominant inheritance, which means that this disorder is carried in a gene in the X chromosome (23rd pair) and will affect any child with one allele.
Given that males only get one X chromosome, while females get two, this condition tends to affect males on a deeper level.
People with Fragile X Syndrome suffer from intellectual disability (the average IQ in males is under 55), characteristic physical features such as a long and narrow face, big protruding ears, flexible fingers and large testicles. Autism and hyperactivity are also common.
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.
A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.
The property of water called high specific heat (it takes water a really really long time to absorb and release heat) caused this difference.
