Genotypes & Phenotypes
If a trait is dd or DD, what is it?
What is Homozygous?
If there is a heterozygous dad, and a homozygous recessive mom, what is the probability for an offspring to be homozygous dominant? (DD)
What is 0%?
What is the definition of genetics?
The study of heredity and the variation of inherited characteristics.
What is breeding?
The process of sexual reproduction.
What is a dominant gene?
What is D?
What is the difference between genotypes and phenotypes?
Genotypes are inherited, while phenotypes are expressed.
Do certain combinations of traits end up in a 50/50 split?
Yes/True.
What is the definition of a trait?
An inheritable characteristic or feature determined by DNA and genes.
What genotype is DD?
What is Homozygous dominant?
What does a recessive trait look like?
lowercase letters (rr, ii,)
If gray fur represents dominant (D), and black represents recessive (d), what fur will you have if you're Dd?
Grey fur/D
True or False: Is there a chance for a combination of traits (like Dd and DD) to have 100% of only one trait
True
What is the definition of a gene?
Segments of DNA that give your cells instructions for specific traits or body functions.
What genotype is Dd?
What is Heterozygous?
Why does the dominant trait always mask the recessive trait?
Thet recessive trait always produces a weakened or non-functional protein
True or False: The phenotype provides the instructions and code for the genotype?
False, it's the other way around.
If the parents are Dd and Dd, what are the chances of not having an offspring with dd?
What is 75%?
What is the definition of a allele?
A varient or alternative form of a specific gene.
True or False: If a homozygous dominant dad and a heterozygous mom have offspring, is there a chance to have a heterozygous offspring?
What is True?
True or False: Does a combination of DD and Dd have a chance of making a DD offspring?
True.
True or False: Phenotypes isn't determined just by genotypes.
True.
What are the chance of having a Dd offspring with DD and Dd parents?
25%
What's the definition of selective breeding?
The intentional process where humans choose to breed plants or animals with specific traits to mate and produce offspring with said specific traits.
What are Mendal's three fundamental laws of inheritance?
What is the Law of Segregation, the Law of Dominance, and the Law of Independent Assortment?
Is blue eyes considered a dominant trait?
No.
