Genes close to each other- Strongly Linked genes

Genes on different chromosome- unlinked genes

Genes apart from each other,but on same chromosome- linked genes

Explanation:

Linkage is defined as the tendency of genes located on same chromosome to be inherited together.

Genes located on different non-homologous chromosome are called unlinked genes.

Genes located on same chromosome are called linked genes.

Genes located close to each other are strongly linked as tend to show complete linkage.

Genes located on different chromosome tend to show incomplete linkage.

Part A Why are Northeast Pacific populations of transient and resident killer whales thought to represent different ecotypes rat

abruzzese [7]

Answer:

<u>Transient killer whales prey on marine mammals, while resident killer whales prey on Chinook salmon</u>

Explanation:

Remember, the term "ecotypes" is used to refer specifically to the observable differences found in the various kinds of whales, which includes <em>their breeding populations, their language of communication, social structure, the type of food they eat, and their hunting behavior.</em>

Thus, in the case of transient and resident killer whales in the Northeast Pacific, they are thought to represent different ecotypes rather than different species the Transient killer whales prey (feed) on marine mammals, while resident killer whales prey on Chinook salmon. Also, whales are generally thought to belong to the same species.

9. Consider the below Punnett square cross. Explain how you could use it to determine which parent

kogti [31]

Answer: The father determines the biological sex of a baby

Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.

What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.
