The Planning ,Research and Development , Corp. is seeking grant money to continue their investigation on the relationship between DNA and heredity.
This is the way my textbook answered it "using the product rule(because the inheritance of each gene is independent), she can make 2x1x1x1= 2 different types of gametes. Please explain.
In humans, red-green color blindness is recessive and X-linked, while albinism is recessive and autosomal. What types of children can be produced as the result of marriages between two homozygous pa
Four Hfr stains of E. coli are known to transfer their genetic material during conjugation in different sequences.
Estrogen receptor (ER) is an important transcription factor, which is up-regulated in 70% of all breast cancers. Using the known ER motif to scan the genome yields many thousands matches.
A population of iguanas on the Galapagos Islands has 20 individuals with webbed feet and 180 individuals with the dominant trait of non-webbed feet. What are the frequencies of webbed feet and non-w
Two pigs whose tails are exactly 25 cm in length are bred over 10 years and they produce 96 piglets with the following tail lengths: 6 piglets at 15 cm, 25 at 20 cm, 37 at 25 cm, 23 at 30 cm, and 5
fur color in rabbits is determined by a single gene locus for which there are four alleles. Four phenotypes are possible: black, Chinchilla (gray color causes by white hairs with black tips), Himala
I believe the answer to this problem is 1/200 females are colorblind. I found the following on the internet: using the information below I determined an approximate incidence to be 1/192.
How does the idea of a lottery apply to your genetic makeup and its expression? In what way? Or does it apply.
A third gene pair on a separate autosome determines whether any color will be produced. The CC and Cc genotypes allow color according to the expression of the A and B alleles. However, the cc genoty
In humans, the ABO blood type is under the control of autosomal multiple alleles. Red-green color blindness is a recessive x-linked trait. If two parents who are both type A and have normal vision p
In cats, yellow coat color is determined by the b allele, and black coat color is determined by the B allele. The heterozygous condition results in a coat pattern known as tortoiseshell.
Each mating results in one of the five offspring shown to the right (a-e). match each offspring with one correct set of parents, using each parental set only once. Is there more than one set of corr
The Human Genome Project began with two goals: to know the sequence of genes on all the human chromosomes and to know the sequence of bases on all the human chromosomes. With this, individuals with
In pings, coat color may be sandy, red, or white. A geneticist spent several years mating true-breeding pigs of all different color combinations.
Workers have long known that mutations cause cancer. A mutagen (substance or form of energy that causes mutations) is usually a carcinogen (substance or form of energy that causes cancer).
Consider a genetic locus that could hold either of the alleles P or p (where P is dominant, p is recessive). Consider a second genetic locus (for some other unrelated trait) that could hold either o
State what difference there would be in the product cells at telophase 2 of meiosis if there had been one crossing over position halfway between the Huntington disease gene and the centromere.
In humans, brown eyes (B) are dominant over blue (b)*. A brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one of whom is blue-eyed.
All living organisms contain genetic information that provides several functions inherent to the individual organism and the perpetuation of its species.
In frogs, being spotted is dominant over striped, and you can tell heterozygotes by their foot structure. Provide allele and expected genotype frequencies for a population containing 74 homozygous s
In a particular species of guppy, tails can either be long or short and either feathered or straight. A cross between a true-breeding long, feather-tailed male guppy and a true-breeding short, strai
How does one's food pattern over time contribute to the development of diseases. What do you think is the interplay between genetics and eating habits.
A short-tailed mutant of mouse was discovered. Multiple crosses of this mouse to normal mice produced 27 normal, long-tailed mice and 25 short-tailed mice.
