What are the genotypes and phenotypes of the offspring of a cross between a TT and a TT plant?
Offspring inherit the genes for particular traits from their parents. The offspring with the genotypes TT and Tt will have a phenotype of tall; the offspring with the genotype of tt will have a phenotype of short. If the two alleles are the same (TT or tt), the genotype is considered purebred.
What is the phenotypic ratio of the offspring if both parents are heterozygous for the trait?
If both parents are heterozygous in a monohybrid cross, the offspring will have a phenotypic ratio of 3:1.
What is the genotype of the black guinea pig?
In Guinea pigs, the genotype (BB) is black, and the genotype (bb) is white color, and (Bb) is grey color, The gene (Bland bare sex-linked.
What is the genotype for guinea pigs?
The genotypes of 2 guinea pigs, for 2 traits are represented as AABB and aabb. The guinea pigs are mated and the offspring eventually mate with eachother.
What is the genotypic ratio of a guinea pig with black fur?
If Bb also gives the guinea pigs black fur then 3 in 4 or 75% of them will be black. If only BB does then only 1 in 4 or 25% will be born with black fur. Paul decides to cross his long haired guinea pig with a short haired guinea pigBoth were homozygous for their traitWhat is the genotypic ratio of the offspring?
Is a guinea pig homozygous or heterozygous?
A guinea pig is homozygous if its two alleles are both dominant or both recessive. Usually, the homozygous parent is the one with either the two capital letters in the genotype or the two lowercase letters. Heterozygous is when there is one uppercase letter and one lowercase letter in the genotype.
Can you cross breed a guinea pig with a possum?
No, guinea pigs and possums can’t be crossed. Guinea pigs are Eutherians while possums are marsupials. Species as far apart as these simply can’t be crossed. A brown guinea pig is crossed with a white one. All of the offspring are brown.
How many dominant alleles does a white guinea pig have?
The brown guinea pig had two dominant alleles for brown color and the white guinea pig had two for white. Since offspring get one allele from each parent they have one dominant brown allele and one recessive white allele.
