4
When an individual has two different alleles, whether dominant or recessive
6
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
8
a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote
10
cross breed, is the result of mixing, through sexual reproduction, two animals or plants of different breeds, varieties, species or genera
11
one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
12
A trait that is controlled by a group of nonallelic genes.
14
predicting the outcome of a genetic cross or of a random experiment
15
stating that when two or more characteristics are inherited, individual hereditary factors assort independently during gamete production, giving different traits an equal opportunity of occurring together
16
is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele
19
a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring
20
A cell or an organism consisting of two sets of chromosomes: usually, one set from the mother and another set from the father. In a diploid state the haploid number is doubled, thus, this condition is also known as 2n
23
the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring
24
When an individual has two of the same allele, whether dominant or recessive
25
containing two complete sets of chromosomes, one from each parent
Down
1
a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum
2
a genetic law that states that the offspring of individuals with contrasting traits will only express the dominant trait
3
a diagram that is used to predict an outcome of a particular cross or breeding experiment
5
a distinguishing quality or characteristic, typically one belonging to a person
7
the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote
9
during the production of gametes the two copies of each hereditary factor segregate so that offspring acquire one factor from each parent
13
any one of a series of three or more alternative or allelic forms of a gene, only two of which can exist in any normal, diploid individual
17
A condition in which both alleles of a gene pair in a heterozygote are fully expressed, with neither one being dominant or recessive to the other
18
structure is an organ, system, or body part that shares a common ancestry in multiple organisms
21
the study of heredity and the variation of inherited characteristics
22
a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell
