What does “Mendel's laws” actually mean in Principles of Inheritance & Variation, and why does it matter for NEET?
the laws of dominance, segregation, and independent assortment govern how traits pass to offspring.
I keep getting “Mendel's laws” questions wrong in Principles of Inheritance & Variation. What's the trap?
thinking both alleles blend rather than segregate.
What does “Monohybrid ratio” actually mean in Principles of Inheritance & Variation, and why does it matter for NEET?
a cross of one trait gives a 3:1 phenotype ratio in the F2 generation.
I keep getting “Monohybrid ratio” questions wrong in Principles of Inheritance & Variation. What's the trap?
confusing the 3:1 phenotype ratio with the 1:2:1 genotype ratio.
What does “Incomplete dominance” actually mean in Principles of Inheritance & Variation, and why does it matter for NEET?
heterozygotes show a blended, intermediate phenotype (red × white → pink).
I keep getting “Incomplete dominance” questions wrong in Principles of Inheritance & Variation. What's the trap?
confusing incomplete dominance with codominance.
What does “Sex-linked inheritance” actually mean in Principles of Inheritance & Variation, and why does it matter for NEET?
genes on the X chromosome (like those for haemophilia and colour blindness) affect males more often.
I keep getting “Sex-linked inheritance” questions wrong in Principles of Inheritance & Variation. What's the trap?
thinking sex-linked traits affect both sexes equally.
What is the difference between genotype and phenotype?
Genotype is the genetic makeup (e.g. Tt); phenotype is the visible trait it produces (e.g. tall).
What is the difference between homozygous and heterozygous?
Homozygous means two identical alleles (TT or tt); heterozygous means two different alleles (Tt).
