In grapes, the wild-type DND1 gene confers resistance to attain viruses, and strains are susceptible to viruses. The EDS1 gene confers resistance to powdery mildew, a type of fungal infection. The genes are linked, eight map units apart on chromosome 17. A third gene, IR 1. imparts resistance to certain lepidopteran leafminers and is 10 map units from EDS1 and 18 map units from UNDI The abserved double crossover rate is 0.3%. What is the interference?
a. 37.5%
b. 25.%
c. 62.5%
d. 75%
Answer:
I = 62.5%
Explanation:
Available data:

The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.
1% of recombinations = 1 map unit = 1cM. The maximum recombination frequency is always 50%.
So, if we know the distances between genes, we know their recombination percentages.
DND1-EDS1 = 8 MU = 8% recombinationEDSI-IR1 = 10 MU = 10% recombinationTo calculate interference, first, we need to know the coefficient of coincidence, CC.
CC= observed double recombinant frequency/expected double recombinant frequency
Note:
observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.CC= (0.003)/(0.08 x 0.1)
CC=0.003/0.008
CC=0.375
CC = 37.5%
The coefficient of interference, I, is complementary with CC.
I = 1 - CC
I = 1 - 0.375
I = 0.625
I = 62.5%

If 2 white dogs mate and produce a brown puppy what color is dominant
Answer:
When dogs breed, the mother and father each randomly contribute one allele from ... The production of melanin is not always at a steady rate so the tip of a dog's hair ... There are two brown alleles, B (dominant brown) and b (recessive brown). ... color patterns such as piebald, particolor, and extreme white which produce ...

1. Which of the following may not likely be possible when a tall man marries a short woman ?
A) All the progeny may be tall.
B) All the progeny may be short.
C) Some of their offspring may be short.
D) Some of their offspring may be short.
NOTE: EXPLANATION IS REQUIRED.
Answer:
The gene for having a tall stature is a recessive trait. So the man can have only as genotype "aa". The short woman can have instead as genotype either Aa or AA. in the first case, we have both tall and short children while in the second case only short children.
So the answer is A) All the progeny may be tall.

Duchenne Muscular Dystrophy (DMD) is a sex-linked trait that causes muscular weakness that gets worse as a person ages. Which is most likely true of Duchenne Muscular Dystrophy? A. DMD can only be inherited by females. B. Females with DMD always have a mother with DMD. C. The gene for DMD is located on the X or Y chromosome. D. The gene for DMD is most active in the cells of the reproductive organs.
Answer: C
Explanation:
DMD is s*x linked trait. This means that we have to consider the chromosomes XX and XY. For a male to have DMD, this means the mom must must pass down the allele for DMD. The mom can either be a carrier OR she has to have DMD and the dad can only pass down the Y chromosome. For a daughter to get DMD, this means the dad has to have the allele for DMD and so does the mom. That means that the dad has DMD and the mom can either have DMD or be a carrier. Based off of this logic, we know that the answer isn't B. Because they tell us DMD is s*x-linked trait, it means that the gene for DMD is on the x or y chromosome.

What causes coral bleaching?(1 point)
High water temperatures boil coral polyps, causing them to turn white in color.
Water acidity and high water temperatures make coral polyps more prone to infection, causing them to turn white in color.
High water temperatures and water acidity cause coral polyps to expel algae, causing them to turn white in color.
Water acidity causes coral polyps to lose their photosynthetic abilities, causing them to turn white in color.
High water temperatures and water acidity cause coral polyps to expel
algae, causing them to turn white in color.
What is Bleaching?This is the process in which a surface is whitened by the removal of its
natural color.
In coral polyps which are found in water, they experience bleaching
through high water temperatures and water acidity.
