How is it genetically possible for parents with both natural brown hair, a dominant phenotype have an offspring with blonde hair, a recessive phenotype?
Both parents have blonde, but have dyed their hair brown.
Both parents have the allele for blonde hair that they passed down to their offspring.
The offspring is not their child.

If a lioness needs 13, 500 kcal to survive and can spend 15,000 kcal on a kill, which is the best food option for her to hunt?
1 Wildebeest - worth 25,000 kcal, cost -10,000 kcal
1 Warthog - worth 12,000 kcal, cost -5,000 kcal
1 Zebra - worth 170,000 kcal, cost -55,000 kcal
1 meerkat - worth 5,000 kcal, cost - 3,000 kcal
Why is it better for lions to live and hunt in groups?
Lions use more energy and provide protection in groups
Lions use less energy and are able to gain more kilocalories from food in groups
Lions raise babies together and males hunt for the family
Lionesses hunt for the family while males raise the babies
Why is inbreeding a potential problem within lion populations?
there can be too much of the same DNA in a population (especially when male lions kill cubs of different families)
there does not seem to be a relationship between inbreeding and lion populations
there are too many different alleles, so genetic diversity is great
How do DNA in lion populations and geography (map locations) relate to each other
lions that are closely related are often very far away
lions that are not related are often very close together
lions that are closely related are usually close together, but some lions migrate, causing widespread similarities
all lions are related
Do these two lion populations have any DNA in common?
Yes, the red genes
No, there are no genes in common
Yes, the green genes
Yes, the yellow genes
Was Lulu (630) the mother of all the cubs? How did we decide?
Yes, she took all of the cubs with her to another pride
No, she was not the mother of any of the cubs
Yes, her alleles matched the letters in all the cubs
No, her alleles only matched one of the cubs
