1. Genetics - ANSWER ✔ The study of heredity and the variation of inherited
characteristics.

present in a cell or organism.
3. Genotype - ANSWER ✔ The genetic makeup of an individual organism,
including all of its genes and alleles.

determine inherited traits.
5. Allele - ANSWER ✔ Different forms or versions of a gene found at the
same locus on homologous chromosomes.
6. Expression (Gene Expression) - ANSWER ✔ The process by which
information from a gene is used to synthesize a functional gene product
(e.g., protein); includes transcription and translation.
,7. Animal Breeding - ANSWER ✔ The selective mating of animals to increase
the occurrence of desirable genetic traits in offspring.
8. Chromosomes - ANSWER ✔ Thread-like structures of DNA and protein
that carry genetic information in the form of genes.
9. DNA (Deoxyribonucleic Acid) - ANSWER ✔ The molecule that carries
genetic instructions used in growth, development, functioning, and
reproduction of organisms.
10.Transcription - ANSWER ✔ The process in which a segment of DNA is
copied into mRNA by the enzyme RNA polymerase.

ANSWER ✔ Tertiary/ graafian follicle
13.match the following anatomical features of the ovary with the destructive
term that best matches that structure - ANSWER ✔ corpus hemorrhagic=
bloody body
corpus luteum= yellow body
corpus allicins = fading remnant of corpus luteum

animal
____ is one member of a gene pair (allele) that is expressed to exclusion of
another allele
_____ is the member of a gene pair that is only expressed when the
dominant allele is absent from the genome - ANSWER ✔ gene expression, a
dominant allele, a recessive allele
, 19._____ is an example of a sex-linked recessive trait in humans - ANSWER ✔
Red/green colorblindness
20.____ is the allele frequency of the dominant allele in the population -
ANSWER ✔ 0.5
