all dominant
FF means forte fortissimo in music!
my guess is that ff stands for Flip Flop ie Back Handspring
ff means 'and following', meaning that the topic of interest continues into the next verses (for a Bible reference) or onto the next pages (for other references.

Alright, I suppose I will do your homework for you.. Here is your punnet square: F F F FF FF f Ff ff Therefore, 3/4, or 75%, offspring will have the phenotype of having freckles, and 1/4, or 25% will have the phenotype of no freckles. And 2/4, or 50%, of the offspring will have the genotype for homozygous for freckles, 1/4, or 25%, of the offspring will carry a heterozygous trait for freckles, and 1/4, or 25%, of the offspring will have the phenotype for homozygous no freckles.
Punnett Squares are useful because they allow you to see the chance of what genes will be handed down to the offspring. They are a quick and easy way to determine the chance of a offspring having a certain characteristic
if you are doing 7th grade life science, it would be B)all dominant because it has FF, FF, Ff, and Ff. All of these has dominant F, so it is all dominant.
The offspring from an FF X ff cross will all have the genotype Ff.This is because they receive one allele from each parent, and in this case they can only receive an F from the FF parent and an f from the ff parent.
If all of the children have freckles, that means that both parents had dominant genotypes. (Mother; FF and Father; FF). Or, one parent could have a hybrid genotype. (For example, Mother; Ff and Father; FF). Based on the outcome of a Punnett Square, either one parent must have a hybrid and the other dominant, or both must have dominant genotypes.
FF, fF, Ff
There different genotypes and two different colors Black fur is dominant --> F White fur is recessive --> f The parents are bot Ff (heterozygotes, and because black fur is dominant they have a black fur). If they mate, you get parents: Ff x Ff Offspring: FF Ff Ff ff so 25% will be homozygous for Black fur 2x25=50% will be heterozygous, and have a Black fur and 25% wil be homozygous for White fur. Hence, of their offspring, 75% will have a black fur and 25% will have a white fur
First, to restate the question in a more comprehensible form:Feather colour in parrots is determined by a single autosomal gene. The gene has two alleles, F and f. F causes blue feather colour and f causes yellow feather colour. F shows incomplete dominance over f (i.e, a heterozygote has a mixed phenotype, green feathers). If two green parrots, genotype Ff breed, what colour will the offspring be?This is a basic Mendelian cross. A similar example, with Punnet square, can be seen in the Wikipedia page for 'Mendelian inheritance', Figure 3. This page is a good starting point for understanding the principles involved.To directly answer the question, 25% of the offspring will be blue (FF), 25% yellow (ff) and 50% green (Ff).
No. Cystic fibrosis is an autosomal recessive disease. Each parent would have to be a carrier of a CF mutation and would be Cc.
Phenotype is physical appearance of a character in a living being which depends on their genotype i.e. genetic constituents so by study of phenotype, genotype can be predicted which may or may not be exactly same but definately not wrong because every character can be homozygously dominant or hetrozygously dominant.
FF-FF-FF-FF-FF-FF
That's called the "MAC address" or "Hardware address". It's a unique set of numbers assigned to a network device. Anything that access the internet whether phones, wireless cards, computers, etc, all have a MAC address. The address with all one's (FF-FF-FF-FF-FF-FF) is the broadcast address. All devices on the physical segment will see and respond to a message with that destination.
