How did Mendel disprove the 'blending inheritance' hypothesis using pea plants? By showing that all offspring were a blend of the two parent phenotypes By proving that inheritance patterns were random and unpredictable By observing that heterozygous offspring (Rr) were as round as the RR parent By demonstrating that all offspring were identical to the wrinkled seed parent

By observing that heterozygous offspring (Rr) were as round as the RR parent

What advantages did garden peas offer to Mendel's genetic studies? They are self-fertilizing and show little variation from generation to generation They have a short life cycle and produce large seeds They can be easily crossbred with other plant species They are resistant to most plant diseases

They are self-fertilizing and show little variation from generation to generation

What are the mechanisms and ratios associated with monohybrid, testcross, and dihybrid crosses? Monohybrid: 1:1, Testcross: 3:1, Dihybrid: 9:3:3:1 Monohybrid: 9:3:3:1, Testcross: 3:1, Dihybrid: 1:1 Monohybrid: 3:1, Testcross: 1:1, Dihybrid: 9:3:3:1 Monohybrid: 9:3:3:1, Testcross: 1:1, Dihybrid: 3:1

Monohybrid: 3:1, Testcross: 1:1, Dihybrid: 9:3:3:1

How does meiosis explain the phenotypic ratios observed in monohybrid and dihybrid crosses? Each chromosome pair separates independently during meiosis Genes are linked and do not assort independently Meiosis does not affect phenotypic ratios All gametes receive the same alleles

Each chromosome pair separates independently during meiosis

How does diploidy protect organisms from recessive genotypes? Recessive alleles are always expressed in diploid organisms All alleles in diploid organisms are dominant A healthy allele can compensate for a damaged or mutated allele Diploidy prevents any mutations from occurring

A healthy allele can compensate for a damaged or mutated allele

What is the difference between incomplete dominance and codominance? Both incomplete dominance and codominance result in a blend of phenotypes Incomplete dominance results in an intermediate phenotype, while codominance results in both phenotypes being expressed Incomplete dominance results in both phenotypes being expressed, while codominance results in an intermediate phenotype Neither incomplete dominance nor codominance affect phenotype

Incomplete dominance results in an intermediate phenotype, while codominance results in both phenotypes being expressed

How does gender affect inheritance patterns, particularly for X-linked genes? Females are more likely to express X-linked disorders X-linked disorders are more common in males because they have only one X chromosome X-linked disorders are equally common in males and females Gender does not affect inheritance patterns

X-linked disorders are more common in males because they have only one X chromosome

What are the similarities and differences between various modes of sex determination? The XO system is identical to the XY system Environmental factors, Haplo-Diplo system, XO system, ZW system Only the ZW system involves environmental factors All systems involve the same number of chromosomes

Environmental factors, Haplo-Diplo system, XO system, ZW system

What is epigenetic inheritance and how does it differ from traditional genetic inheritance? It only affects traits that are visible It does not involve any genetic material It involves phenotypic traits not dependent on DNA sequences It is identical to traditional genetic inheritance

It involves phenotypic traits not dependent on DNA sequences

Why is dosage compensation necessary and how can it affect phenotype? To eliminate all genetic disorders To ensure equal expression of genes from sex chromosomes across sexes To decrease gene expression in females To increase gene expression in males

To ensure equal expression of genes from sex chromosomes across sexes

What hormone is secreted by the hypothalamus, targets the gonads, and affects sexual maturity and function by releasing LH and FSH? testosterone luteinizing hormone (LH) gonadotropin-releasing hormone (GnRH) follicle-stimulating hormone (FSH)

gonadotropin-releasing hormone (GnRH)

What hormone is secreted by the anterior pituitary, targets the ovaries and testes, and affects follicle maturation and spermatogenesis? prolactin growth hormone follicle-stimulating hormone (FSH) luteinizing hormone (LH)

follicle-stimulating hormone (FSH)

What hormone is secreted by the anterior pituitary, targets the adrenal cortex, and increases corticosteroid production? growth hormone adrenocorticotropic hormone (ACTH) thyroid-stimulating hormone (TSH) prolactin

adrenocorticotropic hormone (ACTH)

What hormone is secreted by the anterior pituitary, targets melanocytes of the skin, and increases melanin production? adrenocorticotropic hormone (ACTH) growth hormone melanocyte-stimulating hormone (MSH) thyroid-stimulating hormone (TSH)

melanocyte-stimulating hormone (MSH)

What are the two essential ingredients required for catabolic reactions? Glucose and ATP Organic molecules broken down by intracellular enzymes and oxygen Water and carbon dioxide Proteins and lipids

Organic molecules broken down by intracellular enzymes and oxygen
