In mendelian genetics, how many dominant alleles are needed for a particular trait to show up?

1

When one parent has a homozygous dominant genotype and the other has a homozygous recessive genotype, what are the chances they have a child with a dominant phenotype?

100%

100

When both parents are homozygous dominant genotype, what are the chances they have a child with a recessive phenotype?

0%

This is the study of how traits are passed from parent to offspring

What did Gregor Mendel cross-pollinate in his genetics experiments?
Plants / pea plants

An organism with 2 different alleles for a trait is called a ______.
Hybrid/heterozygous
300
This shows all of the possible outcomes of a genetic cross.
Punnett square
300
This type of organism has 2 different alleles for a trait
Heterozygous

In Mendelian genetics, what happens when a recessive allele is paired up with a dominant allele?

It is hidden / doesn't show up

400
This is a number that describes how likely it is that an event will occur.
Probability
400
This type of organism has 2 dominant alleles for a trait.
Homozygous dominant
400

When one parent has a homozygous dominant genotype and the other has a homozygous recessive genotype, what are the chances they have a child with a recessive phenotype?

0%

400

This process causes organisms with better adaptations to survive and pass on their traits without human involvement.

Natural Selection
400
This type of organism has 2 recessive alleles for a trait
Homozygous recessive
500

This process involves humans choosing which organisms get to reproduce based on desired traits.

Selective Breeding

Different forms of a gene.

This process involves using technology to modify the genetic code for an organism to produce desired traits.

Genetic Modification
