Can o father be the father of ab baby?

No because if you use the Punnet square method, no matter what blood type the mother is, there is no chance that the baby would have an AB blood type.


Why do boys have cooties?

Boys have cooties because they have one brain cell when they are born. To fill the empty space where their other brain cells should be, the bodies of boys create cooties, an undetectable mixture of scents that deflects girls without them noticing. Boys can only create one batch of cooties because of the amount of energy it takes to create it. Cooties are created in the baby boys' early stages but are not released from their empty brain cell until they turn two. As boys get older, cooties slowly seep through the pores in their heads, causing girls to call them "icky" and "gross". Soon, the boys run out of cooties, somehow manage to grow another brain cell, and end up slightly more mature then a first grader.


Predict the results of a cross between a rabbit homozygous dominant for black coat BB and a rabbit homozygous recessive for brown coat color bb?

i think you are asking for the outcome of the offspring, yes? The meathod that i know is to use a punnent square. A punnet square uses the probability to test the genotype (genetic makeup) and phenotype (physical characteristics. You can Google "punnet square" if you wish, to get a full description and how to make one. Here are my results*: there is a... 100% chance of a baby black rabbit (assuming that the black hair is domonant) 75% chance the baby will be homozygous (domonant,pure) 25% chance the baby will be heterozygous (domonant, hybrid) *these results are very general and i am assuming that there is no blending of the traits. (like a gray bunny!) Hope this helped!


Can blood type be determined before birth?

From my research I haven't found a way to know for certain your baby's blood type before birth. You can however narrow it down some if you know the father's and your blood types you could make a punnet square.


What are punnent squares and how are they used?

If you spread out the human brain how many square feet would it be?

If you spread out the human brain it would cover about 4 square feet for a baby. It would cover slightly more than this for an adult.


Can you tell the color of a baby's hair by looking at their parents?

No. However, you can tell the percentage of their eyes being green, blue, brown, or some other color that I am not aware of by looking at their grandparents. You can do so by using a punnet square which is quite easy once you have the hang of it and understand exactly what it is for. I hope my answer satisfied your question. :))


How do Beetle traits vary within the species?

well it depends if they are hetrozygous or homozygus. It could be figured out with a punnet square of 2 parent beatles such as brown could be Bb for hetrozygus and green could be gg for homozygus when u cross them it depends. the first baby would be brown and then the brown would be the dominent trait the green would disapear in the first batch of 4 beetle babies all the way the the second batch would have 3 brown and 1 green.


What will baby be if father is ab- and mother is o?

Using the Punnet square method of gene determination, (which I think is soooo fun, 'cause I'm a lab nerd) the baby's blood group phenotype will be either A or B. Naturally, this is barring some weird mutation, etc. because anything is possible in nature. But, generally if one parent is O and the other is AB, then the child will be either A or B.

How to do a punnett square with sex linked inheritance?

its 2 x's for the woman and and xy for the man and the man determines the sex of the baby because it has the y the y would make it a boy and the x from the father will make it a girl. because the mother only have x's to give the baby. so on the punnet square it would have xx in one box xx in another and xy in another xy in another
