AB blood type in humans as well as, red and white striped flowers are examples of this type of inheritance pattern.
Sati [7]

Answer:

The inheritance pattern is CODOMINANCE

Explanation:

Codominance is a type of non-mendelian inheritance i.e. does not follow Mendel's principles of inheritance, in which two alleles of a gene are both dominant, hence, they are both simultaneously expressed in that gene.

Examples or cases of codominance are the AB blood type in humans where alleles A and B are both expressed in the gene. Also, red and white striped flowers in certain plants is an example of codominance as red and white alleles are both expressed.

If 1000 f2 offspring are obtained, how many flies of each phenotype are expected?
aniked [119]
<span>In Drosophila + indicates wild-type allele for any gene, m is mahogany and e is ebony. Female parents are m+/m+ and males are +e/+e. F1 are m+/+e, all wild type. F1 females are crossed with me/me males - the test cross. Offspring will be : non recombinant m+/me, mahogany wild type or +e/me wild type ebony. OR recombinant me/me mahogany ebony or ++/++ wild type. As the two genes are 25 map units apart, the percentage of recombinants will be 25% and therefore percentage parental types will be 75%. 75% 1000 is 750. There are two parental types, so you would expect 375 of each. Therefore, you would expect 375 m+/me and 375 +e/me. 25% of 1000 is 250 split between two recombinants =125 of each. Therefore you would expect 135 me/me and 125 ++/++</span>
