There are two possible variants of this gene—an allele for long eyelashes (> 1cm) and an allele for short eyelashes (1 cm or less). The allele for long eyelashes is dominant (L) and the allele for short eyelashes is recessive (l). An individual who is heterozygous for eyelash length would produce which of the following gametes? A. None of the gametes would have the eyelash gene; gametes do not have eyelashes. B. The proportion of gametes receiving each allele would be random; the process of meiosis is very disorganized and chromosomes are not separated in an ordered fashion. C. All gametes would have the l allele. D. Half of the gametes would have the L allele and half of the gametes would have the l allele.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
