Question

Sutton and Boveri compared the behaviour of chromosomes and genes. Which of the following statements supports their study?

• A. Dominant allele masks the effect of recessive allele in heterozygous condition
• B. Both chromosomes and genes segregate at the time of gamete formation and each gamete has one member of each pair
• C. Independent pairs of chromosomes do not segregate independently of each other
• D. Any of the statements above can support their study

Answer 1

The correct option is B Both chromosomes and genes segregate at the time of gamete formation and each gamete has one member of each pair

Sutton and Boveri compared the behaviour of chromosomes with genes and found certain similarities. The pair of homologous chromosomes and pair of alleles (alternative forms of gene) segregate at the time of gamete formation and each gamete receives one of each pair.

Independent pairs of chromosomes segregate independently of each other during meiosis.

When two different alleles are present together (heterozygous condition), then one allele dominates the other. This was a finding of Mendel, not Sutton and Boveri.
