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 probability that one of the offspring mice will have black fur?
The answer depends on how big the litter is: as the litter size increases the probability of one black fur increases. But as it gets larger still, the probability falls because two or more black furs become more probable.
A homozygous dominant black bear is mated with a recessive brown bear what phenotype will probably result in the offspring of the two bears?
Phenotype: Black Bear x Brown Bear Genotype: BB x bb Possible gametes: B B b b Possible B B crosses: b Bb Bb b Bb Bb Phenotype of offspring: Only Black bears
What is the probability of drawing black cards from a deck?
The probability is one half.
What the probability of drawing a black card?
0.5
What is the probable phenotype and genotype of offspring of a cross between a horse homozygous for black color and a horse homozygous for chestnut color?
The probable phenotype of the offspring would be black, as black color is dominant over chestnut color. The genotype of the offspring would be heterozygous for black (Bb), since one parent is homozygous black (BB) and the other is homozygous chestnut (bb).
In guinea pigs black hair color is dominant B and white hair color is recessive b What hair color are the guinea pigs offspring?
To determine the hair color of the guinea pigs' offspring, we need to know the genotypes of the parents. If one parent is homozygous dominant (BB) and the other is homozygous recessive (bb), all offspring will be heterozygous (Bb) and will have black hair. If both parents are heterozygous (Bb), approximately 25% of the offspring are expected to be homozygous dominant (BB), 50% heterozygous (Bb), and 25% homozygous recessive (bb), resulting in a 75% chance of black hair and a 25% chance of white hair.
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 female quinea pig homozygous dominant for black fur color is mated with a male homozygous for white fur In a litter of eight offspring there would probably be?
All offspring would inherit one black allele and one white allele, resulting in a heterozygous genotype. Therefore, all eight offspring would likely have black fur, as the black color allele is dominant over white in guinea pigs.
Show the cross between 2 heterozygous dogs. black fur B is dominant to brown fur b?
The Punnett square for crossing two heterozygous dogs (Bb x Bb) would result in a 25% chance of offspring with homozygous dominant black fur (BB), a 50% chance of offspring with heterozygous black fur (Bb), and a 25% chance of offspring with homozygous recessive brown fur (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.
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
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).
What be true to have offspring with black fur?
To have offspring with black fur, both parent dogs must carry the gene for black fur. This gene is usually dominant, meaning that if at least one parent carries it, there's a high chance the offspring will have black fur. If both parents have black fur, then their offspring will also have black fur.
In sheep the allele for white wall parentheses A is dominant over the allele for black wall parentheses a how do you determine the genotype of a white ram or male sheep?
To determine the genotype of a white ram, breed him with black females. Black females are homozygous recesive for the black trait, a. If the ram is homozygous dominant, all offspring will be white (and heterozygous). If the ram is heterozygous, approximately half of it's offspring will be white and half will be black.
How can you tell whether a black guinea pig is homozygous or heterzygous when black fur is dominant over white fur?
To determine if a black guinea pig is homozygous or heterozygous for black fur, you would need to cross it with a white guinea pig. If the offspring are all black, then the black guinea pig is homozygous. If any white offspring are produced, then the black guinea pig is heterozygous.
What is the probability that one of the offspring mice will have black fur?
The answer depends on how big the litter is: as the litter size increases the probability of one black fur increases. But as it gets larger still, the probability falls because two or more black furs become more probable.
