red flowers (R) are dominant to white flowers (r). The offspring of a cross between two red-flowered plants show the fallowing phenotype ratio:
3 red-flowered plants to 1 white-flowered plant

what are the genotypes of the parent plants?

I'm really struggling with this genetics concept, I figured if someone could walk me through the steps of these practice questions, it could help me to learn this. How do I set up the punnett squares for these and ratios?



1) In cats the genotype (BB) is black. Bb is tortoise shell, and bb is yellow. The gene is on the X chromosome. A tortoise shell female is crossed with a black male. What offspring would be expected? Would you normally expect to find any tortoise shell males?

2) Occasionally a tortoise shell male is found, and when found in sterile. Suggest an explanation for the occurrence of tortoise shell males.

3) A couple with a newborn baby are troubled that the child does not appear to resemble either of them. Suspecting that a mix up occurred at the hospital, they check the blood type of the infant. The baby has type (O) blood. Because the father is type (A), and the mother is type (B), they conclude that a mistake must have been made. Are they correct?

In a town, many people have a lethal gene causing clotting blood at birth. It is present in 1 out of 500 births. It kills ONLY when homozygous dominant. If population is 12,000 compute gene frequency for normal and for lethal.


I tried but got lost!

Assume that the trait in accompanying pedigree is due to simple Mendelian inheritance.
a) Is it likely to due to a dominant allele or a recessive allele? Explain.
b) What is the meaning of the double horizontal line connecting 111-1 with 111-2?
c) What is the biological relationship between 111-1 and 111-2?
d) If the allele responsible for the condition is rare, what are the most likely genotypes of all of the persons in the pedigree in generations 1, 11 and 111? (Use A and a for the dominant and recessive alleles, respectively)?

I thought bees were frozen and died in the winter and somehow new bees were born? They say bees are fed sugar water instead of honey ...would it help to put out a feeder with honey for bees?How can bees disappear and no one knows anything about it?
