When a brown guinea pig was crossed with a white guinea pig her offspring were all brown why?

This is probably the result of the brown genes being dominant and the white genes being recessive.
this is correct.

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
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.
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?
Assuming black allele exhibits complete dominance and the white allele is recessive, the genotype is Bb.
Suppose two white flowered pea plants are crossed and produce 1000 offspring how many of those offspring would you expect to have white flowers?
224
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
A black erminette chicken is crossed with a white erminette chicken what color are the offspring?
The offspring are black feathered because the black feather gene is dominant
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(:
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!!!!!
If a homozygous black guinea pig is crossed with a homozygous white guinea pig what is the probability that an offspring will have black fur?
100% because BB is dominant over bb and all the crosses make Bb
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.
If a female fruit fly heterozygous for red eyes crossed with a white eyed male what percent of their offspring would have white eyes?
50%
purple petal color in pea plants is dominant to white petal color two heterozygous pea plants are crossed what is the ratio of the offspring with white petals to the number total number of offspring?
3:1 ratio Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio
