Animal Reproduction Ag Science

What advantage has asexual reproduction over sexual?

• Rapid colonisation

• Genetic diversity

• Needs gametes

• Less competition

Organisms that may reproduce asexually

• Animals

• Fungi

• Bacteria

• Plants

The advantage of sexual reproduction

• Fast

• Needs two parents

• Increases genetic variation

• Overcrowding

When offspring produced as a result of crossbreeding two dissimilar animals is genetically superior to either of its parents

• Inbreeding

• Hybrid vigour

• Heterozygous

• Heterosis

A somatic cell is

• haploid

• diploid

• triploid

• polyploid

Gametes are produced by

• mitosis

• interphase

• meiosis

• genetic engineering

The primary reproductive organs of either system are called

• uterus

• penis

• gonads

• vas deferens

Function of the epididymis

• Transports sperm from testes to urethra

• Carries urine out of the body

• produces male gamete

• stores and matures sperm

The cervix is located

• At the funnel end of the fallopian tubes

• Between the uterus and fallopian tube

• At the opening of the uterus

• At the exit of the urethra

A gilt should not be served for her first oestrus as

• She is too young

• She will prematurely terminate pregnancy

• Lower litter size

• Mammary glands are undeveloped
