Two brown guinea pigs are crossed All but one of the offspring is brown The one is white Why?
The Allele that causes guinea pigs to be brown in color is a dominant one and the white guinea pig's alleles are recessive. 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. Since the dominant trait is the one that is going to be apparent, it would only make sense for all the offspring to be brown in color.
When a black guinea pig is crossed with a white guinea pig and the litter contains a white offspring the genotype of the black haired parent contains?
4 offsprings
What if a homozygous black guinea pig BB is crossed with homozygous white pig b what is the probability that an offspring will have lack fur?
If a homozygous black guinea pig (BB) is crossed with a homozygous white guinea pig (bb), all offspring will inherit one black allele (B) from the black parent and one white allele (b) from the white parent, resulting in heterozygous offspring (Bb). Since black fur is dominant over white fur, all offspring will have black fur. Therefore, the probability of an offspring having black fur is 100%.
What is the genotype of a black guinea pig if it is crossed with a whites guinea pig and they have 4 offspring that are black and 2 offspring are white?
The black guinea pig is likely heterozygous (Bb) for coat color, while the white guinea pig is homozygous recessive (bb). The black guinea pig passes on a black allele to all offspring, resulting in 4 black (Bb) and 2 white (bb) offspring.
A black guinea pig crossed with an albino guinea pig produces 12 black offspring When the albino was crossed with a second black one 7 blacks and 5 albinos resulted What is the best explanation?
No idea i am guessing it is kinda like people. if a black and a white cross it is a 50/50 chance the child will be black or white so its unpredictable it was a 50/50 chance the baby pigs would be blacks or albinos. hope this helps YOU ARE SO RACIST!!!!!
Out of 200 offspring of heterozygous brown rabbits and white rabbits how many white rabbits would be expected?
Half of the offspring, or 100 rabbits, would be expected to be white when offspring from a heterozygous brown rabbit and a white rabbit are produced. This is due to the dominant-recessive inheritance pattern where brown is dominant and white is recessive.
Two black guinea pigs were mated together thirteen offspring were black and four were white what arithmetic ratio of black to white offspring does this approximate?
no dont let them
If a homozygous black guinea pig is crossed with a white guinea pig what is the probability that an offspring will have black fur?
depends if the black fur gene is dominant.. if it is... then yu would cross BB with bb making all heterozygous genotypes(Bb) therefore, having all possible offspring with black fur so theres a 100% probability of offspring with black fur(:
Two true-breeding pea plants are crossed one with purple flowers and the other with white. Their offspring are?
If two true-breeding pea plants are crossed their offspring will show the dominant trait. The flowers will be purple or light purple.
Is it possible that the cross between two black Guinea pigs in puberty square a would not produce a white guniea pig?
Yes, it is possible for a cross between two black guinea pigs to produce offspring that are not white. If both black guinea pigs carry recessive genes for coat color, such as the gene for white fur, there is a chance their offspring could inherit those genes and be white. However, if both parents are homozygous for the black coat color, all offspring will be black. Thus, the outcome depends on the specific genetic makeup of the parent guinea pigs.
Should a Guinea pig have a brown salt lick or a white one?
Guinea pigs should have a white salt lick, as brown or colored salt licks may contain added ingredients that are harmful to their health. White salt licks are pure and safe for guinea pigs to consume in moderation.
What is the genotype of the parent guinea pigs if they give birth to a brown guinea pig if the parents are white?
i have no idea what you are talking about!
