Monohybrid Crosses definitions Flashcards

Having two identical alleles for a specific gene, either both dominant or both recessive.

An allele that masks the effect of a recessive allele in a heterozygous organism, determining the organism's phenotype.

An allele that is masked by a dominant allele and only expressed phenotypically when two copies are present.

Having two different alleles for a specific gene, one inherited from each parent, resulting in a mixed genotype (e.g., Aa).

A grid used to predict the genotypes of offspring from a genetic cross, showing how alleles from each parent combine.

The initial generation in a genetic cross, consisting of two homozygous parents, one dominant and one recessive, used to produce the first set of offspring.

The first generation of offspring from a cross between two homozygous parents, one dominant and one recessive, resulting in all heterozygous individuals.

The generation resulting from the cross of two F1 individuals, typically showing a 3:1 ratio of dominant to recessive phenotypes.

The third generation of offspring in a genetic cross, derived from the mating of individuals from the second filial generation.

Refers to the offspring generation in genetic crosses, typically denoted as F1, F2, etc., indicating the sequence of generations derived from a specific set of parents.

A cross between two heterozygous organisms for a single gene, resulting in a 3:1 phenotypic ratio in the offspring.

A variant form of a gene at a specific locus on a chromosome, responsible for different traits.

Haploid cells involved in sexual reproduction, carrying half the genetic information of the parent, which combine during fertilization to form a diploid zygote.

Observable traits of an organism resulting from the interaction of its genetic makeup and environmental influences.

The genetic makeup of an organism, consisting of the specific alleles inherited from its parents, determining its potential traits.
