Consider a diploid organism. What is the genotypic ratio expected to be observed in the offspring produced by two heterozygous parents

See the answer below

Explanation:

A diploid organism is one that has 2 copies of each of its genes. When the two genes are the same, they are said to be homzygous, and when they are different, they are said to be heterozygous.

In this case, let us assume that the trait in question is represented by A for the dominant version and a for the recessive version. Since the parents are heterozygous, it means their genotypes would be Aa.

      Aa    x    Aa

   AA   Aa   Aa   aa

Hence, the genotype ratio would be 1AA:2Aa:1aa. In other words, the genotypic ratio of homzygous to heterozygous offspring would be 1:1 because AA and aa are both homzygous while Aa is heterozygous.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

answer: although many types of viruses can cause a common cold, rhinoviruses are the most common culprit. a cold virus enters your body through your mouth, eyes or nose. the virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. theres your answer
