In a cross between two black guinea pigs what is the probability that an offspring will be black?
So I took the worksheet and found that in Punnett Square A (if you have the same worksheet) It has the pairs BB, Bb, Bb, and bb. B= black and b= white. The probablility of a black guinea pig is likely and white is unlikely since there is only 1 trait with 2 recessive alleles.
What else can I help you with?
What is the probability that an offspring will be black in the cross shown in punnett square B?
If you want to ask questions about something that is "shown", then I suggest that you make sure that there is something that is shown.
What is the probability of getting a diamond and a black 7?
The probability of getting a diamond and a black seven is zero. Diamonds are red.
What is the probability of drawing a black card and a 7?
To calculate the probability of drawing a black card and a 7 from a standard deck of 52 cards, we first determine the total number of black cards and the number of 7s in the deck. There are 26 black cards (13 spades and 13 clubs) and 4 sevens in the deck. The probability of drawing a black card and a 7 is calculated by multiplying the probability of drawing a black card (26/52) by the probability of drawing a 7 (4/52), resulting in a probability of (26/52) * (4/52) = 1/26 or approximately 0.0385.
What is the probability of picking a black ace?
The probability of picking a black ace in one random draw from a normal pack of playing cards is 1/26.
What is the probability of getting a black face card?
There are 6 black face card in a deck of 52 cards, so the probability of getting a black face card is 6/52 = 3/26
What is the probability of two black guinea pigs having black offspring?
depends on the two guinea pigs genotypes. could be anywhere from 75 to 100 percent.
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%.
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(:
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.
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.
What kind of cross might tell you if a black guinea pig is BB or Bb?
A test cross with a homozygous recessive guinea pig (bb) would reveal the genotype of the black guinea pig. If all offspring are black, then the black guinea pig is most likely homozygous dominant (BB). If both black and white offspring are produced, then the black guinea pig is likely heterozygous (Bb).
Calculate the probability that an offspring will be black in the cross in punnet square b what is the probability it will be white?
In a monohybrid cross with black as dominant (B) and white as recessive (b), the probability of an offspring being black is 75% (3/4) and the probability of being white is 25% (1/4) according to the Punnett square ratios.
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
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
Can two black-coated guinea pigs produce an offspring with a whit coat?
Yes
In rabbits the allele for black fur B is dominant over the allele for brown fur b. Calculate the probability of a homozygous dominant (BB) offspring resulting from a cross between two parents with the?
To calculate the probability of a homozygous dominant (BB) offspring from a cross between two rabbits, we need to consider their genotypes. If both parents are heterozygous (Bb), the possible offspring genotypes would be BB, Bb, Bb, and bb, giving a probability of 1 out of 4, or 25%, for a homozygous dominant (BB) offspring. If one parent is homozygous dominant (BB) and the other is heterozygous (Bb), the probability of BB offspring is 1 out of 2, or 50%.
What Guinea pig coat color is determined by a single gene. The allele for black coat color is dominant to brown. In a cross between two black-haired guinea pigs 20 offspring are born. If both parents?
If both parents are black-haired guinea pigs and the black coat color is dominant, they could either be homozygous (BB) or heterozygous (Bb) for the black coat gene. If both are heterozygous (Bb), the offspring ratio would typically be 25% homozygous black (BB), 50% heterozygous black (Bb), and 25% brown (bb). Therefore, among the 20 offspring, we would expect around 15 to be black (BB or Bb) and about 5 to be brown (bb) if the parents are Bb. If both parents are homozygous (BB), all offspring would be black.
