Answer: Half of the black F2 progeny is expected to be heterozygous.
Explanation: I used a Punnett square to predict the next generations’ alleles.

<span>The words are synonyms, if you look it up in a dictionary you can find that a fetus is "an unborn or unhatched offspring of a mammal, in particular an unborn human more than eight weeks after conception". However, in organisms that reproduce sexually, an embryo develops from a zygote, the single cell resulting from the fertilization of the female egg cell by the male sperm cell. The aforementioned zygote possesses half the DNA of each of its two parents. Moreover, for plants, animals, and some protists, the zygote will begin to divide by mitosis to produce a multicellular organism, which in turn will create and embryo.</span>

Answer:
Genes aren't eradicated from natural selection, but the chances of getting the phenotypes (the physical attributes of an organism based on the genes) go down as the organisms with those phenotypes die out.
Explanation:
Recessive genes are still present in, for example, a heterozygous genotype. but since there is a dominant, it covers the recessive gene and the phenotype won't have anything to do with the recessive gene (unless we are talking about incomplete or codominance).
