Lulu the Lion Quiz

Terms and Concepts RElated to Finding Parentage

TermDefinition
karyotype picture displaying the chromosomes of an individual
How are the chromosomes in a karyotype arranged? Chromosomes are arranged in pairs, based on the shape, size, and the genes they contain.
chromosome tightly coiled DNA proteins; contain genes, found in nucleus of all cells
gene segments of DNA that code for specific traits (Ex: eye color, hair type, etc.)
genotype two alleles of the same gene
heterozygous two different alleles (Ex: A/B. F/f, 118/126)
homozygous two of the same alleles (Ex: A/A, f/f, 118/118)
In addition to a karyotype, what is needed to determine the parentage of an offspring, such as a lion cub? To determine the parentage, it is necessary to have the alleles from both the mother and father to compare to the offspring's alleles.
A n organism has a total of 48 chromosomes in each body cell. What is the "n" number of chromosomes? The "n" number would be 24 (48/2=24).
If the "n" number of chromosomes for an organism is 19, what is the" 2n" number? The "2n" number would be 38 ( 2 (19) = 38).
How many chromosomes does each parent give when creating their offspring? "n" or "2n"? Each parent gives "n" number of chromosomes when creating their offspring, which gives the offspring a complete set.
