In rabbits, gray hair (G) is dominant to white hair (g), and black eyes (B) are dominant to red eyes (b). These two traits are independent of each other. In other words, a female rabbit with the genotype
GgBb
may produce eggs with the alleles GB, Gb, gB, or gb.
What is genotype of black bunny?
If a rabbit is a black color, than their B-series gene is either
“BB” or “Bb”
. Remember that even though the rabbit is black, it can still have a chocolate gene that they can pass to their offspring.
What is rabbit genotype?
Genotypes are a series of letters that represent the genes that color the fur of a rabbit. There are 5 main loci that every rabbit has:
A, B, C, D, & E
. A rabbit will receive two genes for each category from its parents, creating the color and genotype of your rabbit.
What is the phenotype of a rabbit with genotype BB?
A population of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype).
Brown rabbits
have the genotype BB or Bb. White rabbits have the genotype bb. The frequency of the BB genotype is 0.35.
What is the genotype of a heterozygous rabbit?
A heterozygous white rabbit is crossed with a homozygous brown rabbit. The parents’ genotypes are
Rr and Rr
. The offspring’s genotypes are 25% RR, 50% Rr, and 25% rr, which means their phenotypes are 75% red and 25% white. The parents’ genotypes are TT and Tt.
What is the rarest rabbit color?
American Blue Rabbit
They were first known as the German Blue Vienna, but because of World War I, it was changed to the American Blue Rabbit. It is unique to North America and has become the rarest rabbit breed in the United States.
Why is my white rabbit turning GREY?
A rabbit will have darker fur during the summer. In the winter, as the days grow shorter, less melanin is produced. This, in turn, means that a
rabbit’s new coat will lack pigmentation
. In snowy climes, it’s quite common for a rabbit’s fur to turn completely white.
What is the genotype for gray and white bunnies?
Directions: In rabbits, gray hair (G) is dominant to white hair (g), and black eyes (B) are dominant to red eyes (b). These two traits are independent of each other. In other words, a female rabbit with the genotype
GgBb
may produce eggs with the alleles GB, Gb, gB, or gb.
What color is a rabbit?
Nearly all wild rabbits are the
same light brown colour
, which means they are camouflaged in their natural habitat. The different colours of domestic rabbits have come about through selective breeding.
What is a fawn rabbit?
A fawn rabbit is
an agouti rabbit
, with the black colour genetics and the shaded ee gene marker. Its phenotype looks like this: (A_, B_, C_, D_, ee). When bred with a self rabbit, at least half the babies will have the agouti gene.
What are the difference between phenotype and genotype?
The genotype is a set of genes in the DNA which are responsible for the unique trait or characteristics. Whereas the phenotype is
the physical appearance or characteristic of the organism
. … Such traits are hair color or type, eye color body shape, and height, and many such more.
Is PP genotype or phenotype?
A simple example to illustrate genotype as distinct from phenotype is the flower colour in pea plants (see Gregor Mendel). There are three available genotypes, PP (
homozygous dominant
), Pp (heterozygous), and pp (homozygous recessive).
How do you determine phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by
its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes
.
Are floppy ears dominant or recessive in rabbits?
In rabbits, black hair is dominant to brown hair. Also in rabbits,
long straight ears are dominant to floppy ears
. 1. A male rabbit with the genotype BBee is crossed with a female rabbit with the genotype bbEe The square is set up below.
What is the genotype of a pure short plant?
+ WHAT IS THE GENOTYPE OF A PURE SHORT plant? =
TT tt
Make a cross between a HOMOZYGOUS TALL plant and a PURE SHORT plant. … 4 Theterozygous Page 5 MAKE SOME HETEROZYGOUS MONOHYBRID CROSSES A black coat (B) is DOMINANT in guinea pigs.
What is the difference between homozygous tall and heterozygous tall?
Complete answer: Heterozygous is a condition when there are two different traits of a particular gene. Homozygous is a condition when there are identical traits of a particular gene. … Heterozygous tall (Tt) is crossed with
homozygous tall
(tt) to determine the dominant and recessive trait.
