A series of two point crosses is carried out between genes for brown eyes (bw), and arc wings (a), vestigial wings (vg) , ebony body color (e), and curved wings (cv). The following number of nonrecombinant (NR) and recombinant progeny (R) were obtained from each cross.

Genes in cross Progeny (NR) Progeny (R)
a,bw 2224 117
a,cv 2609 823
a,e 3200 3200
a,vg 5172 2379
bw,cv 4614 1706
bw,e 4150 4150
bw,vg 2796 1434
cv,e 3116 3116
cv,vg 2102 305
vg,e 4559 4559


Required:
Using these data form two-point crosses, create a genetic map for these genes, providing the order of the genes and your best estimates of the distances between them.

Which of the following diseases causes dogs to have a chronic cough?

You remove pus from a wound and try to identify the pathogen multiple ways. The multi-locus gene tree showed your organism was most closely related to Streptococcus pyogenes but the 16S tree said it was most closely related to Streptococcus pneumoniae. Describe why this might be the case and other ways you should try to identify this organism.

What enables neighboring water molecules to hydrogen bond with eachother

Carbon is getting stuck in reservoirs (atmosphere and ocean) which is leading to climate
change. Which of the following is not a reason for this issue?
O Decrease in plants means more carbon in the atmosphere
Increase in plants means more carbon in the atmosphere
O Less organisms in the oceans prolongs decomposition trapping carbon in the ocean
O Increased use of factories and burining of fossil fuels increases amount of carbon in the
atmosphere

Which of the following is an example when an uncontrolled experiment is best?

When testing the effect of water on a lawn
When working with the human body
When testing the effect of sugar on a starch
When testing plant growth

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.

What are photosynthesis’s main inputs and outputs of matter and energy?

What is a map? How are maps used, and what is their purpose?

A cold front creates what kind of weather?

In humans, the dominant allele N causes an abnormal shape of the patella in the knee, whereas n is the recessive normal allele. A separate gene is concerned with finger length, and the dominant allele B causes abnormally short fingers, whereas b is the recessive normal allele. A study focused on people who have both abnormal patellae and short fingers. These individuals were N/n . B/b in genotype, having inherited the N allele from one parent and the B allele from the other parent. These N/n . B/b people mated with normal spouses, producing 40 progeny classified as follows: Normal 3 Abnormal knees and short fingers 2 Abnormal knees only 17 Short fingers only 18

Explain why the four types of children were found in the proportions shown.

Draw the chromosomes of (i) the parents of the N/n . B/b individuals; (ii) the N/n . B/b individuals; and (iii) the four types of children, showing the proper positions of the alleles based on the data above.
