Other types of inheritance

Question 1

Incomplete inheritance

Answer 1

The phenotype of a heterozygous individual is intermediate between that o parents. One allele (dominant) isn’t comp dom over other (recessive) showing a physical blend of both

Question 2

Codominance

Answer 2

Both alleles in a heterozygous organism are expressed and contribute to the phenotype.
The two alleles don’t blend but are rather both present in the offspring alongside each other.
Examples- Checkered chickens, roan horses, roan cows, variegated clover. or in the human’s blood group, BM and BN are anti m and, neither is om so possible alleles are BM BM, MN MN, OR BM MN (both anti)

Question 3

multi alleles

Answer 3

more than 2 alleles for a particular characteristic, the position of that gene on a chromosome is called multiple allelic. Multiple alleles can only be studied in populations since each individual only has 2 alleles for a trait.

Question 4

ABO BLOOD

Answer 4

blood groups are inherited and based on the fact that an individual can possess 2 of 3 alternative alleles; IA, IB, or i (found in the same position along chromosome 9). IA and IB are co-dominant and i is recessive

Question 5

POLYGENIC INHERITANCE

Answer 5

determined by more than one pair of genes.
phenotypes exhibit continuous variation, each different gene permutation results in small phenotypic change.
autism, cancer, and type 2 diabetes are polygenic.
Polygenic inheritance is responsible for many phenotypic traits.
Examples: skin pigmentation, height,
