The probability of a homozygous recessive offspring resulting from a cross between two homozygous dominant individual is?
It depends on the parents. The parent could have two dominant genes which would give a 0% chance of the offspring being recessive. The only way that the offspring could have a recessive characteristic is if the both parents have one dominant and one recessive gene, a 25% chance. The chance that both parents would pass on the recessive gene (if they have one dominant and recessive gene) is also 25%, because there is a 50% chance for each parent.
What do F1 in genetics?
Genotype is a same gene type that is carried by a parent to offspring. Phenotype is appearance, lets say a parent has big ears and the child inherit the big ears.
What is the medical term meaning homozygous condition resulting in the formation of abnormal hemoglobin that distorts certain blood cells?
sickle cell anemia
If a heterozygous red eyed female fruit fly mates with a heterozygous red eyed male fruit fly the ratio of the resulting offspring that will have red eyes is while the remaining r?
If red eyes are dominant, then 75% will have red eyes and 25% will have white eyes. The genetic breakdown is: 25% will be RR (homozygous red eyes), 50% will be Rr (heterozygous red eyes) and 25% will be rr (homozygous white eyes).
Are pure breed self fertilizing pea plants capable of producing offspring exactly alike?
Yes, pure breed self-fertilizing pea plants are capable of producing offspring that are very similar or identical to their parents. This is because they are genetically homozygous, meaning they have two identical copies of each gene, resulting in a high degree of genetic uniformity. However, small variations can still occur due to genetic mutations or environmental factors.

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 would mating between a true breeding purple flowered pea plant and a true breeding white flowered pea plant produce?
Make a Punnet Square:White HETEROZYGOUS---WwRed HOMOZYGOUS--ww (this one is recessive because the white characteristic dominated in the heterozygous type)So:W ww Ww www Ww wwThese four are the potential types of the offspring, they will either be HETEROZYGOUS WHITE or HOMOZYGOUS RED, no homozygous white
If you breed a cremello mare to a homozygous black stallion the resulting foal will be?
Buckskin or Smoky Black
What would happen if the gene for a curled tail was not passed from a pig to its offspring?
Straight tails are the wild type configuration. Straight tails are recessive and curly tails are dominant. So a Pig would have to be Cc (heterozyous) or cc (homozygous) for the strait tail characteristic to be passed on to it's offspring. The resulting offspring would only have the potential for straight tails if the other parent carried the recessive, straight tailed gene or was straight tailed.

What is the dominant trait when a red-eyed fly mates with a blue-eyed fly resulting resulting in offspring that all have red eyes?
red eyes

What does it mean if a plant is true breeding?
Mendel started out with plants that "bred true". That is, when tall plants were self-pollinated (or cross-pollinated with others like them), plants in following generations were all tall; when the short plants were self-pollinated (or cross- pollinated with others like them) the plants in following generations were all short.
What is the number of offsprings from a genetic cross the closer the resulting offspring numbers will expected values?
liter
