Difference between law of dominance and law of segregation
Answers
Answer:
Explanation:
Law of segregation-according to the law of segregation during the gamete formation the two forms of each character separate or segregates.
Law of dominance-every individual have two forms for each characteristic the form which can expect it safe alone is dominant form and the form which cannot Express itself alone is and recessive form.

Answer:
Law of Segregation
Meiosis is the process of creating sperm and egg gametes. Each gamete contains half (haploid) the number of chromosomes an individual needs, so fertilization results in the offspring receiving one allele for a trait from each parent. The law of segregation states that the parental genes must separate randomly and equally into gametes during meiosis so there is an equal chance of the offspring inheriting either allele. No allele is favored or has an advantage over another.
Mendel observed segregation in his experiments when parental pea plants with two traits produced offspring that all expressed the dominant traits, but their offspring expressed dominant and recessive traits in a 3:1 ratio. As part of this work, Mendel discovered that he could predict the color and height of the offspring.
Law of Dominance
This law says inheriting an allele has nothing to do with inheriting an allele for any other trait. The alleles from parents are passed on independently to the offspring. After fertilization, the resulting zygote(s) can end up with any combination of chromosomes from the parents and all the possible combinations occur with equal frequency.
Like segregation, independent assortment occurs during meiosis, specifically in prophase I when the chromosomes line up in random orientation along the metaphase plate. Crossing over, the exchange and recombination of genetic information between chromosomes also occurs in prophase I and adds to the genetic diversity of the offspring.
