3:4 or 75%
The probability is 3/4 or 75%. If both parents are heterozygous for the seed shape trait (e.g., Rr), there is a 50% chance that each parent will pass on the dominant allele (R) for round seeds to the offspring. The probability of inheriting the dominant allele from both parents and producing round seeds is therefore (1/2) x (1/2) = 1/4 or 25%. Since there are two possible ways to inherit the dominant allele (from either parent), the total probability is 2 x (1/4) = 1/2 or 50%.
Heterozygous parents have the same odds of identical twins as the general population. Identical twins do not run in families and, therefore, twinning is not related to genetics. Comparisons among different ethnic groups rule out an ethnic cause-no difference. Only mother's age correlates with twinning: the older the mother, the greater the likelihood.
offspring will be produced in following AA :Aa:aa and is in the ratio of 1:2:1 so the probabiltiy is 50%
A monohybrid cross is a cross between parents who are heterozygous at one locus; ... The results The wrinkled trait --- which had disappeared in his hybrid ...of them produced both types of seeds in the F3 and - once again - in a 3:1 ratio

3:4 or 75%
It is a 75% chance that the seeds will be round.
It can happen when both parents are a heterozygous
75% because the recessive and dominant genes are corresponding and in a Punnett square it takes over.
75%
A purebred organism is the offspring of two homozygous parents, having either two dominant alleles, AA or two recessive alleles, aa. A hybrid is the offspring of two heterozygous parents, Aa.
Both of the parents were heterozygous with the blonde hair allele, which is recessive. When there are two parents that are heterozygous, there is a 25% chance their offspring will get two of the recessive alleles. A punnett square can be useful when determining the different phenotypes and genotypes possible in offspring
They R pretty wierd!
A cross between two homozygous parents will form a 100 percent chance of a heterozygous offspring. One homozygous parent must have the dominant allele, and the other must have the recessive allele. So, if the circumstances are correct, these characteristics will make for a 100 percent chance of a heterozygous offspring.
It is identical to the parents.
By the process of hybridization, breeders cross two genetically different organisms. The purpose is to have the best traits of both parents.
