Lab Activity Blood Type Pedigree Mystery Answer Key Upd Link

The blood type and earlobe analysis allows for the exclusion of other family members. As from sources like Brainly confirm, the conclusion often points to a grandchild who is not a direct blood relative, making them jealous and the most likely culprit.

An AB parent can never have an O child, and an O parent can never have an AB child.

Here is the updated pedigree:

Let's check the Smith Family: Mr. Smith (Type A) x Mrs. Smith (Type B). If Mr. Smith is heterozygous ( IAicap I to the cap A-th power i ) and Mrs. Smith is heterozygous ( IBicap I to the cap B-th power i ), they can produce an IAIBcap I to the cap A-th power cap I to the cap B-th power For the Rh factor: If Mr. Smith is heterozygous and Mrs. Smith is , they have a 50% chance of producing an Rh- child Baby Y belongs to the Smith Family . Matching Baby X (O-) Baby X's Genotype: lab activity blood type pedigree mystery answer key upd

connecting a male and female indicate a mating pair (parents).

| Blood Type (Phenotype) | Possible Genotype(s) | | :--- | :--- | | | IAIA or IAi | | B | IBIB or IBi | | AB | IAIB | | O | ii |

Arthur and Eleanor can produce a child with any blood type. The blood type and earlobe analysis allows for

The updated answer key differs from older versions in several key ways:

Can you determine the genotypes of each family member?

To solve the mystery, you must apply the genetic rules for both the ABO blood system and earlobe attachment: ABO Blood Types: This is a multiple-allele system showing codominance cap I to the cap A-th power cap I to the cap B-th power are both dominant over cap I to the cap A-th power cap I to the cap A-th power cap I to the cap A-th power i cap I to the cap B-th power cap I to the cap B-th power cap I to the cap B-th power i cap I to the cap A-th power cap I to the cap B-th power Rh Factor: Follows simple Mendelian dominance where is dominant over Earlobe Attachment: Typically treated as an autosomal trait where free-hanging ) is dominant over 2. Construct the Family Pedigree Here is the updated pedigree: Let's check the

A family pedigree shows blood types for several individuals across two generations. You must determine possible genotypes and trace inheritance of ABO blood groups and Rh factor to identify the likely parentage and explain contradictions.

Conclusions:

Before delving into the mystery, one must master the rules of the game. Human ABO blood types are determined by a single gene with three alleles: ( I^A ), ( I^B ), and ( i ). The ( I^A ) and ( I^B ) alleles are codominant, meaning both are expressed when present together (resulting in type AB), while ( i ) is recessive to both. Thus, six possible genotypes yield four phenotypes:
