1 answer:
Answer:
22 map units
Explanation:
Linked genes may be defined as the genes present on the same chromosomes and they are inherited to the next progeny. The linked genes produces the recombinant progeny.
Distance between the linked gene = No. of recombinants / total number × 100.
Here the parental are 198 Tall Yellow, 192 Short Green.
The recombinant progeny are 54 Tall Green, and 56 Short Yellow.
Distance =
Distance =
Distance = 22 map units.
So, the distance between the genes are 22 map units.

If this is the picture you are talking about, the right answer is non-disjunction
Non-disjunction is the non-separation of homologous chromosomes at the time of cell division which results in the formation of ova or spermatozoa leading to an abnormality in the number of chromosomes of the egg thus fertilized by the spermatozoa.
The fertilized egg consists of either a single chromosome, what is called monosomy, or, conversely, three chromosomes, this is called trisomy. While naturally, the fertilized egg has a single pair of chromosomes.
