Selective Breeding
Humans choosing organisms with desired traits to reproduce is called this.
What is selective breeding?
This structure is where DNA is found in eukaryotic cells.
What is the nucleus?
A rabbit with white fur (a recessive trait) most likely has this genotype.
What is homozygous recessive?
This structure is found inside eukaryotic cells and controls cell activities.
What is the nucleus?
Differences in traits among individuals of the same species are called this.
What is variation?
When breeding poodles and Labrador retrievers, what are humans trying to get?
Desired trait
This molecule carries instructions for traits like eye color and freckles.
What is DNA?
What is the allele for heterozygous using the letter r?
Rr
This molecule is found inside the nucleus and carries genetic information.
What is DNA?
In a sunflower field, taller plants reproduce more successfully because of this process.
What is natural selection?
How can humans reduce hip dislocation in future dog generations?
Choosing dogs with less hip dislocation traits.
Segments of DNA that code for specific traits are called these.
What are genes?
A homozygous dominant parent cannot pass on this type of allele.
What is a recessive allele?
This is where a gene is found.
What is on a chromosome (on DNA)?
Sexual reproduction increases variation because of these processes.
What are meiosis, crossing over, and random assortment?
This determines how amino acids are arranged to form a protein.
What is the sequence of bases (nucleotides) in DNA?
If absent-mindedness is a dominant trait, this percent of offspring are likely to inherit it.
What is 75%?
This is the smallest unit of life that can carry out all life processes.
What is a cell?
Selective breeding differs from natural selection because of this key factor.
➡️ What is human control of reproduction?
The best long-term strategy to protect corn from a new disease affecting the Zea species involves doing this.
What is increasing genetic variation by breeding with wild varieties?
This is the correct order from smallest to largest: gene, DNA, chromosome, nucleus.
What is gene → DNA → chromosome → nucleus?
A cross between a homozygous dominant and heterozygous parent produces offspring with these possible genotypes.
What are homozygous dominant and heterozygous?
This is one of the chemical building blocks of DNA that pairs with another base to form the genetic code.
What is a nucleotide base?
Having low genetic diversity in crops can lead to this major risk.
What is increased vulnerability to disease and environmental change?
