Mendel’s research on breeding peas led him to formulate two laws. His first law, the Law of Segregation, was discovered while he was doing single-trait crosses. This law can be stated as follows:
| A. |
During mitosis, homologous chromosomes assort independently. |
|
| B. |
One allele is always dominant to another. |
|
| C. |
During meiosis, the two genes of each homologous pair separate from each other, ending up in different gametes. |
|
| D. |
Hereditary units from the parents are blended in the offspring, forming an intermediate phenotype. |
Homework Answers
Ans.) Option A : During meiosis, the two genes of each homologous pair separate from each other, ending up in different gametes.
Explanation: Law of segregation states that two alleles present at same locus on homologous pair of segregate from each other by process of meiosis and different types of gametes are produced having single copy of each form of alleles.

Which observation suppose mendel’s second law that copies of different genes assort independently? A) during prophase of meiosis, non sister chromatids will enhance genetics information b) At the end of meiosis II four haploid gametes are generated that each contain the same gene at the corresponding loci. c) At the end of meiosis I, homologous chromosomes are found in separate daughter cells d) during metaphase I, nonhomologous chromosomes will line up randomly along the equatorial plane e) none of the...

1. If two strains of true-breeding plants that have different alleles for a certain character are crossed, their progeny are called a. the P generation. b. the F1generation. c. the F2generation. d. F1crosses. e. F2progeny. 2. Mendel’s crossing of spherical-seeded pea plants with wrinkled-seeded pea plants resulted in progeny that all had spherical seeds. This indicates that the wrinkled-seed trait is a. codominant. b. dominant. c. recessive. d. Both a and b e. Both a and c 3. Segregation of...

In peas, flower location and
plant height are controlled by genes that follow Mendel’a law. One
allele at each locus is donminat to the other at that locus: (i)
AXIAL FLOWERS (A), terminal flowers (a), and (ii) TALL PLANT (T),
short plant (t). A pure breeding plant for the dominant traits is
mated with pure breeding plant for the recessive traits. What
possible gametes can F1 individuals that interbreed make?
