Autosomal linkage

Question 1

The genes carried in the sex chromosomes are said to be sex linked. The remaining 22 chromosomes are called what?

Answer 1

Autosomes

Question 2

What is the name given to the situation where two or more genes are on the same autosome?

Answer 2

Autosomal linkage

Question 3

If autosomal linkage with same heterozygous parents, (RrYy)
what would be expected from when they reproduced?

Answer 3

RRYY, RrYY, RrYy, rryy

Question 4

What is the ratio of phenotype that presents with autosomal linkage?

Answer 4

Ratio of phenotypes would be 3:1

Question 5

Scientists can observe different results that create different phenotype ratios, why do they find these ratios?

Answer 5

This is only possible because crossing over must have occurred during meiosis to make new combinations of gametes

Question 6

What does autosomal linkage mean?

Answer 6

Autosomal linkage means alleles for each gene are linked on the same chromosome will be inherited together
