The probability that an individual heterozygous for a cleft chin and an individual homozygous for a chin without a cleft will produce offspring that are homozygous recessive for a chin without a cleft is fifty percent.
You can calculate this by making a Punnet square.
Its a 50% chance. According to the Punnett square, the possibilities for the offspring of a homozygous recessive parent and a heterozygous to be a homozygous recessive are "Aa", "aA", "aa", or "aa", making it 50% possible.
Only if the generations before were homozygous recessive as well. When doing the punnett square and you see there is a chance of having a heterozygous trait then that specie is not a purebred. The organism's offsprings must have the same physical traits.
A test cross helps to predict the probable, not actual, outcome of a genetic cross. This is what a Punnet Square is used for. You can cross just one gene, or you can do more complicated crosses that involve many genes. For example, if your genotype is heterozygous brown eyes and homozygous blonde hair, your spouse has homozygous blue eyes and heterozygous brown hair, and you want to see the chances of your kids having blue or brown eyes and blond or brown hair, you could do a test cross to see all the possibilities.
A monohybrid cross is a cross between two individuals that are homozygous for different alleles of the same gene. An example is a cross between a red-eyed (RR) fruit fly and a white-eyed (WW) fruitfly.
The offspring's genotype will be AA. Both parents are homozygous dominant, AA, having only dominant alleles to pass on to their offspring. So each parent can pass on only the dominant allele (A) to its offspring. So the offspring will also be homozygous dominant, AA.
In general, pink flowers tend to be an example of incomplete dominance of the gene for red flowers. Therefore, the phenotypic ratio of a cross between two pink flowers would be the same as the genotypic ratio of 1:2:1. In other words, 1 red to 2 pink to 1 white.
a homozygous trait is when an offspring has either both dominant genes or both recessive genes from its parents. a heterozygous trait is when an offspring has both dominant and recessive genes. for example: a long-tailed cat is dominant and a short-tailed cat is recessive. the long-tailed cat (homozygous dominant) had offsprings with the short-tailed cat (homozygous recessive). by doing the punnett square, 100% of their offspring will be heterozygous.
punnett square
Red color being governed by a dominant gene, all offsprings from this cross will have red flowers.
It is called a punnet square.

how many offsprings do dolphins usually have
2 through 12 offsprings
The resulting offspring will have the dominant trait. It depends on if the dominant is hetero or homo...if it was homozygous then your offspring will have a hetozygous trait showing the dominant trait (to clear this up if you are confused lets say we are talking about brown eyes(BB-dominant) vs blue eyes(bb-recessive)--a homozygous would give you a brown eyed child with Bb and but if the person is heterozygous Bb and gets with a recessive you have a chance of getting Bb or bb giving you a possibility of a brown or blue eyed child)...wow i just made that way more confusing than it had to be
woolly monkeys might have 4-5 offsprings in a month.
The offspring's genotype will be AA. Both parents are homozygous dominant, AA, having only dominant alleles to pass on to their offspring. So each parent can pass on only the dominant allele (A) to its offspring. So the offspring will also be homozygous dominant, AA.
