What would the phenotype be for BB?
Phenotype. The physical appearance of the genotype is called the phenotype. For example, children with the genotypes ‘BB’ and ‘Bb’ have brown-eye phenotypes, whereas a child with two blue-eye alleles and the genotype ‘bb’ has blue eyes and a blue-eye phenotype.
What kinds of gametes would be produced by the solid black rabbit?
5. What kinds of gametes would be produced by the solid black rabbit? Solid ss and Black BB. sB gametes will be produced.
Is Black genotype or phenotype?
The appearance of an animal (or any other form of life) is considered its phenotype (think ph = physical). An animal’s genotype is its genetic make-up (think gen = genetic). Black is the phenotype of a calf with at least one black (B) allele. Red is the phenotype of a calf with two red (bb) alleles.
What is the genotypic ratio in male and female cross?
The genotypic ratio for this cross is written 1:2:1. In animals and plants, each gene has 2 alleles or variations, one from each parent. When male and female gametes come together (cross) all the phenotype variations for the offspring are predicted using the Punnett square grid.
What are the different kinds of genotypes produced?
There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).
Which gene is responsible for the albino variety of rabbit?
Mutations in the tyrosinase (Tyr) gene are known to cause recessive albinism in humans and other species. In this study, to test whether the CRISPR/Cas9 system works on the mutation of the UTRs regulatory region in rabbit, the 3′ UTR of the rabbit Tyr gene was deleted by a dual sgRNA directed CRISPR/Cas9 system.
Which is an example of a genetic allele?
Definition: An organism’s genetic makeup or allele combinations Example: An example of a genotype would be HH is the homozygous dominant trait for brown eyes and hh would be the homozygous recessive trait for blue eyes.
Which is an example of an expressed phenotype?
Definition: An allele whose trait (phenotype) is always expressed when present in the genotype. Example: A father has brown eyes with the genotype of HH. A mother has green eyes with the genotype of hh. The son has brown eyes with a genotype of Hh. and his brown eyes are the expressed phenotype, and the green eyes are the nonexpressed phenotype.
Which is the best example of a genotype?
Example: An example of a genotype would be HH is the homozygous dominant trait for brown eyes and hh would be the homozygous recessive trait for blue eyes. Example: Both Parents have blue eyes.
Which is an example of a hybrid rabbit?
Their grandchild was born with red hair. Example: HH or hh or BB or bb and so on. Example: An example of a hybrid, would be when a homozygous dominant black rabbit breeds with a homozygous recessive white rabbit, their offspring will be hybrids.
Why does the first rabbit have a dominant allele?
The first rabbit is heterozygous, so it has a dominant allele. Since it is white, the dominant allele must be for the white trait. Since the black rabbit is homozygous, and the white allele is dominant, the black allele must be recessive.
Which is dominant a white rabbit or a black rabbit?
The first rabbit is heterozygous, so it has a dominant allele. Since it is white, the dominant allele must be for the white trait. Since the black rabbit is homozygous, and the white allele is dominant, the black allele must be recessive. “What is the difference between codominance and incomplete dominance?”
Which is the dominant allele of a brown mouse?
3) A homozygous dominant brown mouse is crossed with a heterozygous brown mouse (tan is the recessive color). 4) A heterozygous white rabbit is crossed with a homozygous black rabbit. The first rabbit is heterozygous, so it has a dominant allele. Since it is white, the dominant allele must be for the white trait.
What happens if you cross a black rabbit with a white rabbit?
4) A heterozygous white rabbit is crossed with a homozygous black rabbit. The first rabbit is heterozygous, so it has a dominant allele. Since it is white, the dominant allele must be for the white trait. Since the black rabbit is homozygous, and the white allele is dominant, the black allele must be recessive.
