Question

spongebob and bikini bottoms genetics worksheet scientists at bikini bottoms have been investigating the genetic makeup of the organisms in the community information provided and your knowledge of genetics to answer each question 1. for each genotype below, indicate whether it is a heterozygous (he) or homozygous (ho). tt he bb he dd ho ff he tt ho dd ho dd he ff ho tt he bb ho bb ho ff ho a. which of the genotypes in #1 would be considered purebred? b. which of the genotypes in #1 would be hybrids?

Explanation:

Step1: Recall pure - bred and hybrid definitions

Pure - bred genotypes are homozygous (two identical alleles), and hybrids are heterozygous (two different alleles).

Step2: Identify pure - bred genotypes

Homozygous genotypes from #1 are TT, DD, tt, dd, rr, bb, BB, FF.

Step3: Identify hybrid genotypes

Heterozygous genotypes from #1 are Bb, Ff, Dd, Tt.

Answer:

A. TT, DD, tt, dd, rr, bb, BB, FF
B. Bb, Ff, Dd, Tt
