n cattle, an autosomal mutation called Dexter produces calves with short stature and short limbs. Embryos that are homozygous fo

timofeeve [1]

Answer:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Explanation:

Dexter is deleterious in homozygous condition, hence, phenotypes are heterozygous.

Roan are also heterozygous.

If dexter allele is represented by D, non dexter individuals will be DD dexter individuals will have the genotype Dd.

If colour in cattle is represented by R, red individuals will be RR, white will be rr, then roan colour will be Rr.

Hence, roan dexter cow and roan dexter bull will both have DdRr genotypes.

Crossing the two: DdRr x DdRr

Progeny:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Others that are either aborted or stillbirths include:

1 ddRR

2 ddRr

1 ddrr

HURRY!!! TELL ME EVERYTHING U KNOW ABOUT HURRICANES (lol i almost put hypnosis)

Hurricanes are large, spiraling tropical storms that can pack wind speeds of over 160 mph and unleash more than 2.4 trillion gallons of rain a day.[1]
The deadliest U.S. hurricane on record was a Category 4 storm that hit the island city of Galveston, Texas, on Sept. 8, 1900. Some 8,000 people lost their lives when the island was destroyed by 15-ft waves and 130-mph winds.[2]
Over 1/3 of cat and dog owners don't have a disaster preparedness plan in place for their animals. Help neighbors and friends come up with a hurricane plan for their pets. Sign up for Save Our Pets.[3]
In the Atlantic, hurricane season starts June 1, while in the Pacific it starts May 15. Both end on November 30.[4]
When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge.[5]
40% of the hurricanes that occur in the United States hit Florida.[6]
The difference between a tropical storm and a hurricane is wind speed – tropical storms usually bring winds of 36 to 47 mph, whereas hurricane wind speeds are at least 74 mph.[7]
Hurricanes rotate in a counter-clockwise direction around the eye. The rotating storm clouds create the "eye wall," which is the most destructive part of the storm.[8]
Hurricanes are classified into 5 categories, based on their wind speeds and potential to cause damage. Names can be "retired" if a hurricane has been really big and destructive. Retired names include Katrina, Andrew, Mitch and most recently Sandy.[9]
When the National Hurricane Center began giving official names to storms in 1953, they were all female. This practice of using only women’s names ended in 1978.[10]
The costliest hurricane to make landfall was Hurricane Katrina, a Category 5 storm that slammed Louisiana in August of 2005. Damages cost an estimated $108 billion.[11]

If the DNA code is CCA, what is the complementary mRNA code?

ELEN [110]

Answer:

The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain. The anticodon is the complementary three nucleotide sequence in the appropriate tRNA.

An individual heterozygous for eye color, skin color, and number of eyes mates with an individual who is homozygous recessive fo

sukhopar [10]

Answer:

B) 1 black eyes, green skin, two eyes : 1 black eyes, green skin, one eye : 1 black eyes, white skin, two eyes : 1 orange eyes, green skin, two eyes : 1 orange eyes, white skin, two eyes : 1 orange eyes, white skin, one eye

Explanation:

Parentals: BbGgCc x bbggcc

The punette square diagram of the cross of these two parents is attached.

B = black eyes, b = orange eyes;

G = green skin, g = white skin;

C = two eyes, c = one eye

Progeny with BbGgCc genotype → black eyes, green skin, two eyes = 8

Progeny with BbGgcc genotype → black eyes, green skin, one eye = 8

Progeny with BbggCc genotype → black eyes, white skin, two eyes = 8

Progeny with bbGgCc genotype → orange eyes, green skin, two eyes = 8

Progeny with Bbggcc genotype → black eyes, white skin, one eye = 8

Progeny with bbGgcc genotype → orange eyes, green skin, one eye = 8

Progeny with bbggCc genotype → orange eyes, white skin, two eyes = 8

Progeny with bbggcc genotype → orange eyes, white skin, one eye = 8

So, if we will see them in the form of ratio then each of the genotype will be in the ratio of 1 i.e. black eyes, green skin, two eyes: black eyes, green skin, one eye: black eyes, white skin, two eyes: orange eyes, green skin, two eyes: black eyes, white skin, one eye: orange eyes, green skin, one eye: orange eyes, white skin, two eyes : orange eyes, white skin, one eye = 1:1:1:1:1:1:1:1.

So, in view of above option B is most appropriate.

Note: In a trihybrid cross, a total of 64 progeny types may be produced.
