Go to the OMIM website (http://www.ncbi.nlm.nih.gov/omim) and locate the Search button at the top of the page. Use the Search function to look up, one by one, the following three human hereditary diseases that are relatively common in certain populations: 'Tay–Sachs disease' (select OMIM number 272800 from the search results list); 'cystic fibrosis' (select OMIM number 602421 from the search results list); and 'sickle cell anemia' (select OMIM 603903 from the search results list). For each of these diseases, look through the information and provide the following details:
On which chromosome is the gene for the disease located?

Breeding two pure-lines of yellow-seeded flowers will always produce yellow-seeded offspring
A
True
B
False

1
Understand the concept of pure-line breeding: Pure-line organisms are homozygous for a particular trait, meaning they have two identical alleles for that trait.
Identify the genetic makeup of the yellow-seeded flowers: If the flowers are pure-line, they are homozygous for the yellow seed trait, which can be represented as YY.
Consider the inheritance pattern: When two homozygous organisms (YY) are crossed, all offspring will inherit one allele from each parent, resulting in offspring that are also homozygous (YY).
Recognize the dominance of the trait: If yellow is the dominant trait, all offspring will express the yellow-seeded phenotype.
Conclude the outcome: Since both parents are homozygous for the yellow trait, all offspring will be yellow-seeded, confirming the statement as true.
