Name the seven contrasting traits of Mendel.
What are the reasons for Mendel’s successes in his breeding experiment?
A cross between two tall plants resulted in offspring having few dwarf plants. What would be the genotypes of both the parents?
In a testcross involving F1 dihybrid flies, more parental-type offspring were produced than the recombinant-type offspring. This indicates ______.
Mendel’s last law is ______.
In the F2 generation of a Mendelian dihybrid cross the number of phenotypes and genotypes are ______.
Assertion: When the two genes in a dihybrid cross are situated on the same chromosome, the proportion of parental gene combinations is much higher than the nonparental type.
Reason: Higher parental gene combinations can be attributed to crossing over between two genes.
Given below is a dihybrid cross performed on Drosophila.
Which of the following conclusions can be drawn on the basis of this cross? When yellow bodied (y), white-eyed (w) Drosophila females were hybridized with brown bodied (y+), red-eyed males (w+) and F1 progenies were intercrossed, F2 generation would have shown the following ratio:
