Assume a phenotype is determined by one gene with a dominant allele and a recessive allele. If one parent is homozygous recessive and the other is heterozygous, what is the probability that an offspring will have the recessive phenotype?

Phenotype probability

Explanation:

In the given question,let say A is dominant allele and a is recessive  allele Homozygous recessive parent(having both alleles recessive) will be denoted by aa genotype whereas heterozygous parent(one allele is dominant while other is recessive) will be denoted by AaWhen a cross is made between both the parents then the probability of offspring having the recessive phenotype will be 1/2 or we can say 50%

When the ball is rising up, it gains kinetic energy. when the ball reaches the very top, it will have all potential energy, until it falls back down and gains it kinetic energy. finally when you catch the ball or it falls back down, it would have gained its potential energy back.
