Monohybrid Cross

Monohybrid Cross

________ is a genetic mix between two individuals who have homozygous genotypes, or genotypes that have completely dominant or completely recessive alleles, which result in opposite phenotypes for a certain genetic trait.

Predation

________ Is when one organism eats another organism to obtain nutrients.

Commensalism

________ Is a symbiotic relationship where one organism benefits and the second is neither harmed nor helped.

Skin color

________, height, fingerprints Epistasis results when an allele of one gene hides or masks the visible expression of phenotype of another gene.

Milk production

________ in females and Growth of beard in males Sex- influenced traits traits that are expressed differently in the two sexes due to the influence of sex hormones.

Chromosomes

________ are thread- like structures located inside the nucleus of animal and plant cells.

field of biology

Genetics Is a(n) ________ that studies how traits are passed from parents to their offspring.

reproductive cells

The alleles separate from each other in the process called segregation during which ________ are formed.

Autosomal Recessive It

________ skips generation Unaffected parents can have an affected child.

X

________- linked Recessive All sons of affected mother are affected Unaffected father will never have an affected daughter Y- linked Disease Y- linked traits never occur in females, and occur in all male descendants of an affected male.

Symbiosis

________ The act of living together Two organisms that live together Temporarily or for a longer time At least one of the organisms benefits from the relationship Different types of Symbiosis Mutualism Is biological interaction between two species wherein both species benefit from each other.

Blood Type Multiple Alleles

________ A non- Mendelian inheritance pattern that involves more than just typical two alleles that code for a certain characteristic.

Dihybrid Cross

1 trait ________ is a cross between two different lines /genes that differ in two observed traits.

Polygenic traits Polygenic traits

________ are traits controlled by more than one gene and thus, their inheritance can be complicated.

Genes

________ for one trait are not inherited together with other traits.

LAW OF DOMINANCE

________ if an organism inherits different alleles for the same trait, one allele may be dominant over the other.

Codominance Non

Mendelian pattern of inheritance in which the hybrids show the phenotypic characteristics of both alleles

Blood Type Multiple Alleles A non

Mendelian inheritance pattern that involves more than just typical two alleles that code for a certain characteristic
