Homework Answers
17. Option c is the correct answer.
The homozygous recessive individuals will always have recessive character and the genotype will be always homozygous recessive while heterozygous individuals and homozygous dominant individuals both will have dominant character and thus genotype of such individuals is not known.
18. Option c is the correct answer.
If both alleles are different it is known as heterozygous while if both alleles are same they may be homozygous dominant or homozygous recessive.
19. Option d is the correct answer.
Each gamete contains only one allele out of two alleles for a particular character. Since here both alleles are different half of the gamete will have dominant allele and half will have recessive allele.

what is the difference between heterozygous and homozygous individuals
What is the difference between heterozygous and homozygous individuals? Homozygotes have one chromosome while heterozygotes have two similar chromosomes. The homozygote will express the dominant trait and the heterozygote will express the recessive trait. All of the gametes from a homozygote carry the same version of the gene while those of a heterozygote will differ. Heterozygotes carry two copies of a gene while homozygotes only carry one.
